  • Patent number: 5818195
    Abstract: A controller is provided for use with electric motors which will achieve a two mode motor operation. In this operation, a first mode is utilized having a torque configuration thus more efficiently providing high torque outputs from the motor. However, a second configuration is also used which more efficiently accommodates high speed operations albeit at the expense of some output torque. The system accomplishes this two mode operation in a low cost manner so as to minimize the overall cost of products or devices utilizing this power control system.
