摘　　要：介绍了一种基于恒流斩波的运载火箭推力调节电机细分驱动技术。运载火箭发动机推力调节功能由控制系统控制推力调节电机实现。运载火箭推力调节电机细分驱动技术采用了全硬件实现的恒流斩波控制方式,实现对电机绕组电流大小的精确控制,保证了推力调节电机的输出转矩在不同频率下的稳定。A technology of subdivision driving for the launch vehicle engine thrust regulation motor based on constant current chopping is introduced. The engine thrust of launch vehicle is regulated by the control system regarding controlling the thrust regulation motor. The technology of subdivision driving for thrust motor of launch vehicle adopts constant current chopping method by all implemented in hardware,which can precisely keep the current value of motor winding and make the output torque of the thrust regulation motor stable in different frequencies.
