The motors are asynchronous, low voltage three-phase TEFC motors. Type MS (aluminium) size 56-132 and Y2E2 (cast iron) size 160-400. Cast iron motors Y2E2 are available on request from size 80-450. All motors over size 132 have 3xPTC in windings.

The IE1 marine series is IP55 as standard and painted RAL 5010.

440 V Y – Hoyer IE3 motors ≤ 3.5 kW
440 V D – Hoyer IE4 marine motors ≥ 3.5 kW

690V D is available on request with other non-standard voltages.

All motors are supplied with SKF or similar premium bearings. All motors from size 160-400 have heating elements for stand still protection against condensation and tropical windings.
