摘　　要：目前,大部分水下推进器所使用的无刷直流电机存在体积较大、整机笨重、作业范围小等缺陷。通过分析电机设备的换流特性,提出了母线电流的相电整流控制重构方案,经过仿真试验可知,运用该方案进行电机相电流控制优化,能大幅减少电机传感器数量,缩减电机体积,可使电机性能更加符合现代化作业需求。At present,most of the brushless DC motors used in underwater thrusters have defects such as large volume,bulky overall structure,and small operating range.By analyzing the commutation characteristics of motor equipment,a phase current rectification control reconstruction scheme is proposed for bus current.Through simulation experiments,it can be seen that the optimization of motor phase current control by using this scheme can significantly reduce the number of motor sensors and motor volume,and make motor performance more in line with modern operation requirements.
