Air Door Actuator / Motor: Description and Operation
Stepping Motor For Air-blending Damper
The stepping motor has two windings. A voltage is applied to the windings in special order with short pulses. This causes the motor to move in
short steps, hence its name. The direction of rotation can be changed. When the motor is stationary, current is applied continuously to both
windings.
