Stepper Motors

Stepper motors rely on pulses of DC for control. Control circuitry may be intolerant of power supply variation. Large amounts of ripple on the power supply can upset control signals, leading to erratic operation.

Output drivers can fail if they are open- or short-circuited. Excessive heat is a cause of premature failure. Heat sinks on control circuits should be kept clean and well ventilated.

Do not dismantle stepper motors which have a permanent magnet stator. A loss of torque results.
