ABSTRACT:
An impact start assist device for an electric motor comprises a driven member coupled to a load and a drive member coupled to the motor and to the driven member. The driven member and the drive member are rotatable, relative to each other, through at least a portion of a revolution. The device further comprises an arrangement for providing a substantially instantaneous transfer of angular momentum from the drive member to the driven member after relative rotation of the members through at least the portion of the revolution. A locking arrangement is provided for locking the drive member and the driven member together at high rotational speeds. At least a portion of the locking arrangement is centrifugally actuated, and a spring is provided to disengage the locking mechanism at low speeds, or at rest. A spring arrangement is also provided to position the drive member and driven member in predetermined angular positions relative to each other when the drive and driven members slow to a predetermined low rotational speed, or to a stop. In one embodiment, the arrangement for instantaneously transferring momentum from the drive member to the driven member comprises a hammer surface and an anvil surface on the respective members which impact one another after the members have rotated through at least a portion of a revolution. The device may be constructed as a coupler to be situated between a motor and a load, integrally constructed as part of the motor or the load, or integrally designed into the rotor of the motor.
