ABSTRACT:
An improved regulator mechanism for a single-phase or three-phase, two-speed motor is disclosed. The regulator mechanism includes a first energizable contactor (having at least one contact) and a second energizable contactor (having five contacts) which cooperate to cycle the motor between inoperative and operative states and to configure the motor windings and power lines so as to provide first and second speed operation.
