Functional Features:
- High continuous torque for demanding servo applications
- Incremental encoder with differential line driver output
- Robust construction for harsh industrial environments
- Field-wound compatible for custom voltage/torque variants
Structural Features:
- Cast aluminum body with external finned housing for heat dissipation
- Front-mounted encoder with protective cover
- Keyed shaft with retention ring groove
- Thru-bolt mounting flange (NEMA 42 equivalent)
Working Principle: Three-phase sinusoidal commutation. External drive provides commutation signals based on incremental encoder feedback. Velocity and position loops closed externally.
Advantages:
- Proven legacy platform — extensive installed base
- High torque in 104mm frame — 4 Nm continuous
- Wide voltage range — operates from 24V to 325V DC
- Easy field replacement — compatible with AKD and S-Series drives
Applicable Industries:
- Metal cutting (lathes, mills)
- Plastics machinery (injection molding)
- Woodworking (routers, saws)
- Heavy-duty conveyors
- Press machines
Installation Requirements:
- Mount on NEMA 42 pattern flange using M6 bolts
- Shaft coupling: use flexible coupling rated for ≥12 Nm
- Ensure encoder cable shielding is grounded at drive end only
Usage Notes:
- Requires external servo drive (not compatible with AKD PnC series without adapter)
- Allow 10-minute warm-up at rated load for thermal stabilization
- Do not operate above 4500 RPM continuously
