Functional Features:
- 230V AC rated — connects directly to mains-fed servo drive
- Incremental encoder — 2048 lines for high-resolution feedback
- High continuous power — 2.3 kW for sustained industrial duty
- Regenerative braking capability — energy returned to DC bus
Structural Features:
- Cast iron body with aluminum end bells
- External finned housing for forced-air or natural convection cooling
- Front-mounted encoder with IP54 seal
- NEMA 42 mounting flange pattern
Working Principle: Three-phase sinusoidal commutation driven by external AKD or compatible servo drive. Incremental encoder provides velocity and position feedback. Drive performs electronic commutation and closed-loop servo control.
Advantages:
- Direct 230V AC operation — no external transformer required
- 2.3 kW continuous — handles heavy-duty applications
- Robust mechanical construction — cast iron body resists vibration
- Wide speed range — 0 to 4500 RPM
Applicable Industries:
- Metal forming (press brakes, shear machines)
- Plastics extrusion
- Heavy conveyor systems
- Woodworking (large routers, shapers)
- Textile winding machines
Installation Requirements:
- Mount on NEMA 42 flange using M8 bolts, torque 8 Nm
- Use rigid coupling rated for ≥22 Nm peak torque
- Ensure 100mm minimum clearance for airflow
Usage Notes:
- Verify drive is rated for 230V AC input before connection
- Use regenerative braking resistor if deceleration energy exceeds bus capacitor capacity
- Monitor winding temperature via drive thermal model
