Design of Oil-filled Brushless DC Motor for Deepwater Propulsion
Abstract:In this paper, a 6kW oil-filled permanent magnet brushless DC motor is designed. The structure characteristics of oil-filled BLDC motor is presented. The calculation method of the main dimensions of the motor, the selection of electromagnetic load, the structure characteristics and design method of the stator and rotor, and the design method of the permanent magnet are studied. The basic parameters of the BLDC motor are determined by the equivalent magnetic circuit method according to the technical requirements. And then the finite element analysis model of the motor is established in Ansoft Maxwell 2D. The performance of the motor under the no-load and rated load condition is analyzed. Finally, analyze the cogging torque of the motor and present several methods of reducing it.
Keywords: brushless DC motor equivalent circuit method finite element analysis cogging torque
