2 phase genuine leadshine digital stepper motor drive dm882s updated from am882 match for 57hs22 60hs30 86hs35 to 86hs85 stepper

in order to further improve the high frequency response of the drive, an up-conversion boost power drive interface can be used. the voltage supplied to the winding is linear with the operating frequency of the motor. its main circuit is a switching regulator power supply, which uses a frequency-to-voltage converter to convert the frequency of the drive pulse into a dc level, and uses it to control the switching regulator power supply to form a power drive interface with frequency feedback.
