摘　　要：针对大型无人水下航行器低速大扭矩推进电机减振降噪应用需求,设计了一款额定功率100 kW、额定转速250 r/min的低速大扭矩永磁同步电机。首先基于磁路法完成电机电磁方案设计,建立电机分段斜槽有限元模型,开展空载反电势、齿槽转矩、电磁转矩等参数的仿真分析,最后完成样机的研制与试验。试验结果表明文中的低速大扭矩永磁同步电机设计方案切实可行。This study focuses on the requirement of reducing vibration and noise in low-speed,high-torque propulsion motors used by large unmanned undersea vehicles(UUVs).Furthermore,a low-speed high-torque permanent magnet synchronous motor with a rated power of 100 kW and a rated speed of 250 r/min is designed.First,a motor electromagnetic scheme is designed based on the magnetic circuit method.Subsequently,the finite element model of the motor’s segmented skewed slot is established,and the no-load back electromagnetic force,cogging torque,electromagnetic torque,and other parameters are analyzed.Finally,the prototype is developed and tested.Test results indicate the feasibility of the design scheme for achieving a low-speed,high-torque,permanent magnet synchronous motor.
