稀土永磁直流电动机三维静磁场分析

Common DC bus is mainly composed of rectification and inverter unit, with which three-phase alternating current becoming into fixed power direct current, then direct current is again converted into frequency and voltage adjustable alternating current by inverter to control motor speed.

公共直流母线技术主要由整流单元和逆变单元组成，三相交流电经过整流单元以后，变成一定功率的直流电，再经过逆变单元变成频率和电压可调的交流电源，用来控制交流电机的速度。
