Two-speed ship motor for positioning

Menzel Elektromotoren has manufactured a ship motor with two separate windings for different speeds.

The special motor can drive a ship's azimuth thruster at two different speeds thanks to two separate windings

The motor was commissioned by a petroleum company and is to drive an azimuth thruster. The type MEBKSW630-8/10 three-phase squirrel-cage motor is certified by Lloyd's Register. The modular series, which features IP55 ingress protection and IC 81W cooling (air-to-water heat exchanger) by default, enables flexible, cost-efficient customization while at the same time offering a tested and proven design. The ship motor was constructed for a vertical mounting.

The customer attached great importance to smooth commissioning through interchangeability with the previous motor. At a nominal voltage of 6000 V, the 8- and 10-pole rotor windings are designed for nominal outputs of 2000 kW and 800 kW and speeds of 895 rpm and 713 rpm respectively. The size 500 squirrel-cage motor weighs 12.5 tons.

The motor series is also characterized by high power density, high efficiency, high overload capacity and high-durability bearing designs. Menzel also offers explosion-proof motor designs and motors with higher IP protection classes for marine and petrochemical applications.
