Stepping motor driver with mid-frequency stability control
摘要:
In the disclosed stepping motor system a band pass filter extracts error signals from currents in a stepping motor driver, and a feedback system delays command pulses to the driver on the basis of the error signals. This suppresses mid-frequency instabilities in the operation of the stepping motor.
