leadshine ma860h 2 phase stepper drive with 50-110 vdc or 36-80 vac voltage and 2.4-7.2a current pure sinusoidal current control

according to the requirements of the input signal, the switching waveform signal processing of the motor under different states is generated. pwm modulation of the switching signal waveform generated by the loop distributor and filtering and shaping of the relevant waveform 3: pushing stage: amplifying the voltage of the switching signal, and increasing the current to enhance the main switching circuit direct control of each phase winding of the motor with power components
