EM Series
Electric Motors
Three-phase squirrel cage motors for continuous plant duty.
Foot and flange mounted induction motors in IEC frames, supplied to match the gearbox range or as standalone replacements. Four-pole as standard, with two- and six-pole builds to order, and single-phase motors available alongside the three-phase range. Copper wound, Class F insulated, and available in higher efficiency classes.
- Power range
- 0.37 kW to 75 kW
- Single phase
- 0.18 kW to 2.2 kW
- Mounting
- Foot and flange
- Protection
- IP55, Class F
Built for Duty
What separates EM Series from a general-purpose drive.
Copper wound
Full copper windings for lower losses and a cooler running temperature under sustained load.
IE2 and IE3 options
Higher efficiency classes where the duty cycle makes the running cost worth the premium.
Dynamically balanced rotor
Balanced rotors keep vibration low, which extends bearing and coupling life downstream.
Inverter duty
Suitable for VFD control across the usable speed band, with forced cooling available for low-speed running.
Brake motor variants
DC and AC disc brakes for hoisting, indexing and any drive that must stop under load.
Matched to the gear range
Supplied pre-matched to RW, RH and RK units so the drive train arrives as one specification.
