When the motor of a two-wire spring return actuator is operating, the spring?

Explanation:
In a spring-return actuator, the motor winds a spring as it operates. This stores energy in the spring so that when power is removed, the stored energy drives the return to the original position. So the spring is being wound up during motor operation. It isn’t disconnected, it doesn’t assist the motor by helping it turn, and the cam-operated switch isn’t opened by the spring itself—that action comes from the mechanism’s position after actuation.
