Research on Design Method and Electromagnetic Vibration of Six-Phase Fractional-Slot Concentrated-Winding PM Motor Suitable for Ship Propulsion

Blog Article

In the background of high-power propulsion application on ships and existing uncertain electromagnetic and vibration features of multiphase fractional-slot concentrated-winding permanent magnet (PM) motor, the electromagnetic design and analysis methods of six-phase fractional-slot chevy sonic rims for sale concentrated-winding PM motor are presented.Four different pole and slot combination schemes are sifted out, and air-gap magnetic field and electromagnetic force of these four motors are studied in contrast.On the basis of the above, a 20-kW prototype of six-phase fractional-slot concentrated-winding PM motor with 48 slots and 44 poles is designed and manufactured, and its electromagnetic and vibration performances are tested through experiments.The test results are in good 2334-080 agreement with calculations, which could guide the development of high-power ship propulsion.
