IE1 electric motors
Despite an increasing focus on efficiency in the maritime industry, Hoyer IE1 marine motors are still widely used for all types of marine applications.
Hoyer IE1 marine motors are still powerful despite the addition of both IE2 and IE3 motors to the range. IE1 electric motors are manufactured according to international standards under IEC.
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.
