Abstract
A motor operator for a circuit breaker is disclosed. The motor operator includes a motor drive assembly connected to a mechanical linkage system for driving an energy storage mechanism from a first state of a plurality of states to a second state of a plurality of states. The motor operator also includes an energy release mechanism coupled to the mechanical linkage system for releasing the energy stored in the energy storage mechanism. The mechanical linkage system includes a recharging cam being driven by the motor drive assembly. The recharging cam rotates a drive plate rotatably mounted to the system. A linear carriage is coupled to the drive plate and the linear carriage manipulates an operating handle of a circuit breaker. The recharging cam is disengaged from the drive plate when the energy storage mechanism is compressed into an energy storage state and the drive plate is latched into a position corresponding to the energy stored state. The drive plate is released from its latching position by the energy release mechanism and the stored energy of the energy storage mechanism is released to manipulate the handle of the circuit breaker. The recharging cam is reconnected after the energy of the energy storage mechanism has been released.
