分析了四类常见的电动机断相运行,并由此推出和验证了断相运行状态下的电流—电压等比规律。
The digital comparator designed with FPGA generates several PWM current waveform synchronously, to realize the step angles even division control for four-phase stepping motor.并通过FPGA设计的数字比较器,同步产生多路PWM电流波形,实现对四相步进电动机转角进行均匀细分控制。
To achieve the four-phase stepper motor to start, stop control, reversing control.实现对四相步进电机的启动,停止控制、正反转控制。
