BXG Series Stainless Steel Washdown Motor Overview<\/h2>\n

The BXG series represents Korea Ever-Power motor line specifically engineered for hygienic processing environments where aggressive daily cleaning with high-pressure hot water, steam, caustic solutions, or acid-based sanitizers is part of standard operating procedure. Unlike conventional three-phase motors<\/a> with painted cast iron or aluminum housings, the BXG motor uses a seamless stainless steel enclosure that resists corrosion from chlorinated cleaners, peracetic acid, sodium hydroxide, and other chemicals commonly used in food plant sanitation.<\/p>\n

The IP69K protection rating is the highest ingress protection level defined by DIN 40050 Part 9. It certifies the motor enclosure against high-pressure water jets at 80\u00b0C, delivered at 80\u2013100 bar from a distance of 100\u2013150 mm, through a spray nozzle with a flow rate of 14\u201316 liters per minute. This test condition simulates the most demanding CIP (clean-in-place) and COP (clean-out-of-place) procedures found in dairy, meat, and beverage processing facilities.<\/p>\n

The motor housing is manufactured using precision robotic TIG welding inside the frame, resulting in a completely smooth exterior with no visible weld seams, no exposed fastener heads, and no crevices where bacteria or food residue could accumulate. The terminal box is epoxy-encapsulated within the motor frame and sealed with submersible-grade O-rings, eliminating a common failure point for water ingress in conventional washdown motors.<\/p>\n

Why Stainless Steel IP69K Motors Are Required in Food Processing<\/h2>\n
\n
\n

Painted Motors Fail in Washdown Environments<\/h3>\n

Standard painted aluminum or cast iron motors rated IP55 are not designed for direct exposure to high-pressure hot water jets, caustic cleaning solutions, or steam. The paint coating cracks and peels after repeated thermal cycling from washdown temperatures (80\u00b0C water followed by ambient cooling). Once the base metal is exposed, corrosion begins rapidly. Aluminum housings are particularly vulnerable to attack by alkaline (NaOH) and acidic (HNO3) cleaners used in dairy and beverage sanitation. Motor failures caused by water ingress through degraded paint and corroded seals are one of the most common maintenance problems in food processing plants.<\/p>\n<\/div>\n

\n

Hygienic Design Prevents Bacterial Harborage<\/h3>\n

Food safety regulations (including FSMA in the United States, EC 852\/2004 in Europe, and HACCP principles globally) require that equipment surfaces in food contact and food splash zones be smooth, cleanable, and free of crevices where bacteria can hide and multiply. Standard motors with external fans, cooling fin gaps, nameplate edges, and recessed bolt heads create dozens of potential bacterial harborage points. The BXG stainless steel motor eliminates these risks with its smooth, fan-less, crevice-free enclosure that can be fully sanitized by high-pressure spray without disassembly.<\/p>\n<\/div>\n<\/div>\n

Design Features<\/h2>\n
\n
\n

TENV Cooling \u2014 No External Fan<\/h3>\n

The totally enclosed non-ventilated design dissipates heat through the stainless steel housing surface by natural convection and radiation. Without an external fan, there is no air movement that could transfer airborne contaminants between processing zones \u2014 a critical requirement in cleanroom pharmaceutical facilities and allergen-controlled food production areas. The absence of a fan also eliminates the fan cover cavity, a known harborage point for bacteria and debris on conventional motors. TENV cooling is inherently speed-independent, making these motors particularly well-suited for VFD-driven<\/a> variable speed applications.<\/p>\n<\/div>\n

\n

Robotic TIG Welded Construction<\/h3>\n

The motor frame is precision TIG-welded by robotic welding systems inside the housing structure. External surfaces are completely smooth with no visible weld beads, no grinding marks, and no surface porosity. This construction method eliminates the crevices found at traditional bolted or cast joints where bacteria, cleaning chemicals, and moisture can accumulate. The result is a motor surface with a roughness of Ra \u2264 0.8 \u00b5m \u2014 smoother than typical food-grade stainless steel pipe fittings.<\/p>\n<\/div>\n

\n

Sealed Epoxy-Encapsulated Terminal Box<\/h3>\n

The electrical connection chamber is sealed within the motor frame and filled with thermally conductive epoxy resin. This eliminates the traditional removable terminal box cover \u2014 a frequent entry point for water during washdown operations. Cable entry uses IP69K rated stainless steel conduit fittings with dual O-ring seals. The electrical connections are permanently protected from water, steam, and chemical exposure, dramatically reducing the risk of insulation failure caused by moisture ingress.<\/p>\n<\/div>\n

\n

NSF H1 Food-Grade Lubrication<\/h3>\n

All bearings are lubricated with NSF International H1 registered grease approved for incidental food contact per 21 CFR 178.3570. In the unlikely event that a trace amount of lubricant migrates past the shaft seal and contacts food product, it will not create a food safety hazard. The grease is also formulated for long service life in wet environments, maintaining lubrication performance even after repeated exposure to washdown water spray.<\/p>\n<\/div>\n<\/div>\n

Industry Applications<\/h2>\n
\n\n\n\n
\"Stainless<\/p>\n

Food and Beverage Production<\/h3>\n

Conveyor drives, mixers, fillers, slicers, portioning machines, and packaging equipment in meat, poultry, seafood, dairy, bakery, confectionery, and beverage facilities. IP69K protection withstands daily high-pressure sanitation with caustic and acid wash cycles.<\/p>\n<\/td>\n

\"Stainless<\/p>\n

Pharmaceutical Manufacturing<\/h3>\n

Tablet press drives, granulator motors, coating pan drives, and cleanroom ventilation. The fan-less TENV design prevents cross-contamination between production zones. SS316L housing resists pharmaceutical solvents and cleaning agents.<\/p>\n<\/td>\n

\"Stainless<\/p>\n

Chemical and Water Treatment<\/h3>\n

Chemical dosing pumps, mixer drives, and agitators in corrosive atmospheres. SS316L grade provides resistance to chloride-induced pitting corrosion in coastal locations, swimming pool chemical rooms, and desalination plant environments.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

\n
\n

Dairy Processing<\/h3>\n

Pasteurizers, homogenizers, separator drives, CIP pump motors, and cheese processing equipment. Dairy environments combine high humidity, frequent hot water washdowns, and exposure to lactic acid and caustic soda \u2014 conditions that rapidly destroy conventional painted motors.<\/p>\n<\/div>\n

\n

Meat and Poultry Processing<\/h3>\n

Band saws, grinders, sausage fillers, smokehouses, and chilling tunnel conveyors. Meat processing requires the most aggressive sanitation protocols in the food industry, with multiple daily washdowns using chlorinated alkaline detergents at temperatures up to 80\u00b0C.<\/p>\n<\/div>\n

\n

Outdoor and Marine Environments<\/h3>\n

Deck equipment on fishing vessels, aquaculture feed systems, outdoor car wash machinery, and coastal industrial installations. The combination of IP69K sealing and SS316L corrosion resistance provides long service life in salt spray and high-humidity environments where standard motors fail within months.<\/p>\n<\/div>\n<\/div>\n

Stainless Steel Motor with Gear Reducer Combinations<\/h2>\n

For applications requiring speed reduction and increased torque output, our BXG stainless steel motors can be paired with NMRV worm gear reducers<\/a> or stainless steel gearboxes to create a hygienic gearmotor solution. The motor-to-gearbox connection uses an IEC standard input flange, allowing easy assembly and maintenance. For washdown-critical applications, full stainless steel gearbox options with IP69K rated housing are available to match the motor protection level.<\/p>\n

Frequently Asked Questions<\/h2>\n
\n

What does IP69K protection mean in practice?<\/h3>\n

IP69K is the highest ingress protection rating, tested per DIN 40050 Part 9. The motor enclosure withstands direct high-pressure water jets at 80\u00b0C, applied at 80\u2013100 bar pressure from a distance of 100\u2013150 mm through a flat spray nozzle at 14\u201316 L\/min flow rate. The nozzle is directed at all angles (0\u00b0, 30\u00b0, 60\u00b0, 90\u00b0) for 30 seconds each. After testing, no water penetration into the motor interior is permitted. This condition replicates the most aggressive food plant cleaning procedures including high-pressure steam cleaning and caustic foam application.<\/p>\n<\/div>\n

\n

Why is TENV cooling better than TEFC for food applications?<\/h3>\n

TEFC (totally enclosed fan cooled) motors use a shaft-mounted external fan that draws air over the motor housing. This fan can blow airborne allergens, bacteria, or particulate matter from one processing zone to another. TENV (totally enclosed non-ventilated) motors have no external fan, relying instead on passive heat dissipation through the housing surface. This eliminates the air movement risk, the fan cover cavity (a bacteria harborage point), and fan noise. TENV cooling also means the motor thermal performance is independent of shaft speed, making it ideal for variable-speed VFD operation without derating at low speeds.<\/p>\n<\/div>\n

\n

When should I choose SS316L instead of SS304?<\/h3>\n

Choose SS316L when the motor will be exposed to chloride-containing environments (brine solutions, seawater, chlorinated cleaners above 200 ppm), strong acids (sulfuric, phosphoric, hydrochloric), or coastal salt spray atmospheres. Dairy processing, meat processing with brine injection, seafood facilities, and pharmaceutical environments with chloride-based sanitizers are typical applications where SS316L provides measurably longer service life compared to SS304.<\/p>\n<\/div>\n

\n

Can a stainless steel motor be used on a variable frequency drive?<\/h3>\n

Yes, and the BXG series is particularly well-suited for VFD operation. Because TENV cooling does not depend on motor speed, there is no thermal derating at low speeds \u2014 the motor can deliver full rated torque from minimum to maximum frequency without overheating. This is a significant advantage over conventional TEFC washdown motors that must be derated below approximately 30 Hz due to reduced fan airflow. For best results, use a VFD with adjustable carrier frequency and install the motor cable length within the recommended limits.<\/p>\n<\/div>\n

\n

How does the cost compare to a standard washdown motor?<\/h3>\n

A BXG stainless steel IP69K motor is approximately 3 to 5 times the initial purchase price of a standard painted IP55 motor in the same frame size. However, total cost of ownership over a 5-year period is typically lower due to dramatically reduced motor replacement frequency (standard motors in washdown environments often fail every 8\u201318 months), elimination of unplanned downtime costs, and reduced food safety risk. Many food processors report full payback within 12\u201324 months when accounting for replacement motor costs, labor for motor swaps, and production downtime.<\/p>\n<\/div>\n

\n

What is the maximum available power for a stainless steel motor?<\/h3>\n

Our standard BXG catalog covers 0.18 kW to 7.5 kW in IEC frame sizes 71 through 132. The TENV cooling method limits the practical maximum power because all heat must be dissipated through the housing surface without a fan. For higher power requirements above 7.5 kW in washdown environments, we recommend our standard three-phase motor with enhanced marine-grade epoxy coating (rated for regular washdown but not IP69K) or a stainless steel motor housing with an integrated water-jacket cooling system \u2014 contact our engineering team<\/a> for custom solutions.<\/p>\n<\/div>\n

\n

What is the surface temperature of a TENV motor during operation?<\/h3>\n

At full rated load in a 25\u00b0C ambient environment, the external housing surface temperature of a BXG motor typically reaches 55\u201375\u00b0C depending on frame size and power rating. This is below the burn threshold for brief incidental skin contact but should be considered in areas where personnel may come into regular contact with the motor surface. The low surface temperature also means the motor does not create localized hot spots that could affect heat-sensitive food products stored nearby.<\/p>\n<\/div>\n

\n

Are NEMA frame sizes available?<\/h3>\n

Yes. In addition to IEC metric frames, we offer BXG motors in NEMA frame sizes 56C through 215TC for installations in the United States, Canada, and other markets using the NEMA dimensional standard. Both NEMA TEFC and NEMA TENV configurations are available. Voltage ratings include 208-230\/460V 60Hz three-phase and single-phase options in fractional horsepower sizes.<\/p>\n<\/div>\n

\n

What maintenance does a stainless steel motor require?<\/h3>\n

Stainless steel motors require significantly less maintenance than conventional painted motors in washdown environments. There is no paint to inspect or touch up. There is no external fan to check for damage or debris buildup. Bearing re-greasing follows the same interval as standard motors (approximately 10,000 hours for frame 71\u201390, 8,000 hours for frame 100\u2013132). Inspect the shaft seal and cable gland seals annually. Measure insulation resistance at least once per year. The stainless steel surface should be rinsed after each cleaning cycle to remove residual chemical films that could cause discoloration over time.<\/p>\n<\/div>\n

\n

What is the lead time for stainless steel motors?<\/h3>\n

BXG stainless steel motors in SS304 with IEC frame sizes 71 through 100 ship within 15\u201322 business days. SS316L housing and larger frame sizes (112\u2013132) typically require 22\u201330 days due to material sourcing and additional machining time. NEMA frame versions require 25\u201335 days. Contact our sales team for exact lead times and pricing for your specific configuration.<\/p>\n<\/div>\n

Customer Experiences<\/h2>\n
\n
\n

We replaced 22 painted IP55 motors on our poultry processing line with BXG SS304 IP69K units. Before the switch, we were losing an average of 3 motors per quarter to water ingress failures, costing us roughly $4,200 per incident including replacement motor, electrician labor, and lost production. After 14 months with the stainless steel motors, we have had zero failures and zero unplanned downtime related to motor issues. The investment paid for itself within 10 months.<\/p>\n

Our dairy requires SS316L grade on all equipment in the raw milk receiving and pasteurization areas due to the combination of lactic acid exposure and chlorinated CIP chemicals. The Ever-Power BXG motors in 316L have been operating for 20 months with no signs of pitting or surface discoloration. The smooth housing makes sanitation verification during our BRC audit much simpler \u2014 the auditor specifically commented on the absence of bacterial harborage points on the motor surfaces.<\/p>\n

Dairy Processing Cooperative, Christchurch, New Zealand<\/p>\n<\/div>\n

\n

We operate 8 BXG motors on VFDs driving conveyor speed zones in our ready-meal production line. The TENV design means we do not need to derate the motors at low conveyor speeds during product accumulation phases. At 10 Hz, the motors run cool and smooth without the overheating problems we experienced with our previous TEFC washdown motors. The speed stability under varying product load has also improved product spacing consistency on the line.<\/p>\n

Important Technical Note<\/p>\n

The IP69K rating is verified under laboratory test conditions per DIN 40050 Part 9. Actual installed motor protection performance depends on proper cable gland installation, correct tightening torque on all sealed connections, and the condition of shaft seals and O-rings. Inspect all sealing elements during commissioning and replace them at the intervals specified in the motor maintenance manual. The chemical resistance information provided applies to short-term exposure during cleaning cycles; prolonged continuous immersion in concentrated chemical solutions is not covered by the IP69K test protocol. For specific chemical compatibility questions, contact our engineering team with the exact chemical name, concentration, and exposure duration. All specifications conform to IEC 60034 and DIN 40050 standards.<\/p>\n<\/div>\n
