Description
This is a compact low-speed electric motor that is designed for the interface of a specific unit, in particular for its cooling system. The main option is water cooling of the stator per the IC70W/IC71W schemes. The outer diameter reaches 4 m, which corresponds to an IEC frame size up to 2000, and the power depends on the number of poles. The voltage is up to 1000 V, if needed with a dual winding system for supply from several converters, with class F or H insulation. The machine has high efficiency at rated and partial load, is designed for low mass, noise and vibration, is modular and has low maintenance requirements. Separate test stands are created for FAT acceptance tests with the participation of classification societies, and the design complies with IEC 60034 and IACS standards. It suits both new electrically propelled vessels and conversion to a hybrid or fully electric propulsion plant.
How to choose
The power and diameter depend on the number of poles, so the machine is calculated for a specific thruster. In the marine segment the manufacturer also supplies induction and PM synchronous machines for diesel-electric and fully electric vessels in the range of 150–8000 kW at voltages of 400–11 000 V. If you need a standard water-cooled drive, look at the MKH up to 2500 kW with IE4, and for IE5 without magnets a synchronous reluctance motor up to 500 kW.
