Functional Features:
- EnDat 2.2 digital absolute encoder for zero-homing on power-up
- Integrated brake option available (EKCN2 indicates with brake)
- High torque-to-inertia ratio for fast dynamic response
- Sealed construction for dust and moisture resistance
Structural Features:
- Compact cylindrical body with integrated encoder housing
- Front-shaft configuration with keyed output
- Aluminum housing with stainless steel shaft
- Radial and axial shaft seals for IP65 rating
Working Principle: Three-phase brushless commutation driven by external servo drive (e.g., AKD series). Rotor position sensed by EnDat encoder; drive performs electronic commutation based on feedback.
Advantages:
- Zero-homing capability eliminates need for homing routine
- Compact form factor — ideal for space-constrained machines
- High continuous torque density in 42mm frame
- Field-proven reliability across millions of units deployed
Applicable Industries:
- Semiconductor equipment
- Medical devices
- Packaging machinery
- Robotics (small to medium payload)
- CNC spindle drives
Installation Requirements:
- Mount using M4 through-bolts on standard NEMA 17 flange pattern
- Ensure shaft alignment within 0.05 mm TIR
- Use torque-controlled fasteners (2.5 Nm max)
Usage Notes:
- Do not exceed rated voltage or current limits
- Ensure adequate ventilation at continuous rated torque
- Brake variant (EKCN2) requires 24V DC brake supply
