Kollmorgen 60WKS-CE240/06
Product Brief:
The 60WKS-CE240/06 is a stainless-steel servo motor from Kollmorgen’s WKS series, specifically designed for washdown and hygienic environments. The “CE” suffix indicates a specific winding configuration, “240” refers to the frame length, and “06” refers to the winding variant. This motor features a fully sealed stainless steel housing and is rated for high-pressure washdown, making it suitable for food & beverage, pharmaceutical, and life sciences applications.

Functional Features:
- IP69K rated — withstands high-pressure (80 bar), high-temperature (80°C) water jets from any direction
- 316L stainless steel construction — corrosion-resistant, suitable for chemical cleaning agents
- Smooth, crevice-free housing — no areas for bacterial growth (EHEDG compliant)
- Sealed encoder — optical encoder with IP69K-rated seal
- Special shaft seal — double lip seal with food-grade lubricant
- Optional food-grade grease — NSF H1 certified lubricant available
Material Composition:
- Housing: 316L stainless steel (electropolished finish, Ra < 0.8 µm)
- Stator Laminations: Silicon steel with epoxy coating (corrosion-resistant)
- Rotor Magnets: NdFeB, hermetically sealed with stainless steel sleeve
- Shaft: 316L stainless steel, ground to Ra < 0.4 µm
- Bearings: Stainless steel bearings (AISI 440C), sealed, food-grade grease
- Cable Gland: 316L stainless steel, IP69K-rated
- Fasteners: 316L stainless steel hex socket cap screws
Structural Features:
- Cylindrical body with smooth external surface (no sharp edges)
- NEMA 23 flange mounting (4-bolt, 57 mm BCD)
- 19 mm diameter shaft with keyway (or smooth shaft option)
- M23 connector (stainless steel) for encoder and power
- Optional: IP69K-rated connector with cable gland
Operating Principle:
Standard sinusoidal brushless commutation. The servo drive supplies three-phase AC to the stator windings. The permanent magnet rotor follows the rotating magnetic field. The incremental encoder provides position feedback. The sealed construction ensures no contamination ingress during washdown cycles.
Advantages:
- Full IP69K protection — the highest washdown rating available
- EHEDG certified — meets European Hygienic Engineering & Design Group standards
- 3-A Sanitary — accepted by 3-A Sanitary Standards (dairy, food, beverage, pharma)
- Corrosion-free — 316L stainless steel resists all common cleaning chemicals
- Zero bacterial harborage — smooth surfaces, no crevices
Applicable Industries:
- Food & beverage processing
- Pharmaceutical manufacturing
- Dairy processing
- Meat processing
- Cleanroom automation
- Biotech laboratories
- Bottling and canning lines
Installation Requirements:
- Mount on NEMA 23 flange with 316L stainless steel bolts
- Use food-grade coupling (bellows type recommended)
- Cable entry: use IP69K-rated cable gland, torque to 8 Nm
- Ensure no trapped water in cable routing — slope cables downward away from motor
- Ground the motor housing to the machine frame (ground resistance < 1 Ω)
Usage Notes:
- Do not use abrasive cleaning agents — they damage the electropolished surface
- Maximum washdown pressure: 80 bar, temperature: 80°C, distance: 100–150 mm
- Re-grease bearings every 10,000 hours (or per OEM schedule) using NSF H1 grease only
- Do not operate with encoder cable disconnected — will trigger drive fault
- Verify shaft seal integrity annually in high-washdown applications
