Stainless Steel IP69K Motor: Built Tough & Clean
Huifeng’s stainless steel washdown motors are designed for demanding environments. Made with high-grade 304 & 316L stainless steel, they resist corrosion and last longer. Perfect for food, beverage, and pharmaceutical industries.
Why Choose Huifeng's Stainless Steel IP69K Motor
- IP69K Rated – Withstands high-pressure, high-temperature washdowns.
- TENV Construction – Totally Enclosed, o blades or fan cover, no places to trap dirt.
- Large Junction Box – Easy wiring access and maintenance.
- Laser-Engraved Nameplate – Permanent, clear labels for traceability.
- Smooth Surface – No crevices; easy to clean and sanitize.
- Inverter Duty Operation – Runs smoothly on VFDs:
- 4:1 Constant Torque (CT)
- 10:1 Variable Torque (VT)
- Hygienic Cable Gland – EHEDG-certified for sanitary safety.
- Low motor surface temperature – Thanks to the low losses electromagnetic design and excellent process, the surface temperature of motor is low enough, nobody will be scalded by the hot motor

What's the Cooling Principle of Huifeng's TENV Stainless Steel IP69K Motors
TENV (Totally Enclosed Non-Ventilated) motors rely on passive heat dissipation through the motor’s external surfaces. Unlike TEFC (Totally Enclosed Fan Cooled) motors, they have no cooling fan or vents, making them ideal for dirty/wet environments.
How It Works
Internal Heat Transfer
Copper windings transfer heat to the frame via direct metal-to-metal contact.
External Heat Dissipation
The enlarged housing acts as a “heat sink” – heat radiates naturally to ambient air.
In Huifeng stainless steel motors:
→Stainless steel doesn’t conduct heat well. To keep our motors cooler, Huifeng uses the low losses electromagnetic design and excellent process that create less heat.
→ Lack of fan/fan cover eliminates dust traps, improving thermal uniformity.
The Difference Between TENV & TEFC in Washdown Zones
Factor | TENV Motor | TEFC Motor |
|---|---|---|
Cooling Method | Natural convection (no moving parts) | Forced air (external fan) |
Dirt Accumulation | Zero risk (sealed surfaces) | Fan shroud traps debris |
Hygiene | Smooth surfaces survive caustic wash | Fan blades corrode/contaminate |
Motor Power | Usually no more than 1.5kW(2hp) | The max power of Huifeng's TEFC motor is 4kW(5hp) |
Motor Size | Totally round body with compact size | With a welded terminal box, size is bigger |
Real-World Example: Dairy Processing Plant
A TEFC motor failed every 6 months:
❌ Fan blades clogged with cheese residue → Overheated → Burned windings.Switched to Huifeng’s stainless steel TENV motor:
✅ No fan = nothing to clog.
✅ Survived 2+ years of daily 80°C NaOH washdowns.

常见问答
How can the motor cooled down without a motor fan?
TENV motor relys on passive heat dissipation through heat transfer from copper windings to the motor frame via direct metal-to-metal contact.
When designing motors, Huifeng uses more materials to lower the temperature rise of the motors, allowing the motors to achieve thermal balance simply by dissipating heat on the surface of the frame.
Can you make IE3 IP69K motor ?
Yes, we have IE3 IP69K stainless steel motor.
What's IP69k
Dust ingress (“6” = Dust-tight)
High-pressure, high-temperature water jets (“9K” = Resists close-range washdowns with 80°C+ water)
Do you have IP68 motor?
No, IP68 is submersible motor, our motor can not be used under water.
