Product note

Synchronous propulsion motors

Introducing the AMZ propulsion motor  AMZ propulsion motors are synchronous motors designed for

demanding VSD (variable speed drive) propulsion applications

in different types of vessels.

Special attention is paid to the requirements of the classifica-

tion societies as well as customer needs. These include special

bearing requirements resulting from the inclination of the ves-

sel, and requirements with regard to structure-borne noise and

vibration (especially on cruise vessels).

 The motors are des igned for the most demanding conditions

found in engine rooms (high ambient temperature). They aretotally enclosed with air-to-water heat exchangers incorporat-

ing cooling motors with fans. This ensures safe operation

throughout the speed range. The internal cabling is halogen-

free and flame-retardant. The motors have also been designed

with ample space for maintenance.

Why use an electric motor for propulsion? ABB has extensive experience as a motor manufacturer and a

solid reputation for reliability.

 

 The main benefits of ABB’s electric propulsion motors are low

maintenance costs and superior control dynamics.

Precise torque control with ABB frequency converters makes

zero-speed, starting and even the most demanding ice-going

conditions easy to handle. It is these factors that have made

 AMZ motors the world leaders in propulsion applications.
