摘要： A motor controller for an electric motor having a stator and a rotor. The motor controller includes a power input for receiving AC power from a power source; a control input for receiving a control signal from a control; and circuitry for switching power from the power source to the electric motor in response to the control signal. The circuitry is operable to: apply a braking waveform to the stator while the rotor is rotating; monitor a reactive power of the stator; detect an increase in the reactive power of the stator to determine the rotor has substantially stopped rotating; and remove the braking waveform from the stator in response to detecting the increase in the reactive power.

摘要： An electric motor control system includes a power inverter and control circuitry configured to control the power inverter either according to a target voltage in a voltage-based control mode or according to a target current in a current-based control mode. A controller is operable to switch operation of the control circuitry between the voltage-based control mode and the current-based control mode. The controller may be configured to operate the control circuitry in the current-based control mode at lower motor operating speeds where stator current margin is of greater significance, and to operate the control circuitry in the voltage-based control mode at higher motor operating speeds where stator voltage margin is of greater significance.

摘要： An electric motor control system includes a motor control circuit for generating a motor control signal and a braking mechanism for adjusting the motor control signal to augment motor losses when the motor control circuit is in a braking mode. The braking mechanism includes a difference component for receiving a first signal containing motor reference speed information, for receiving a second signal containing actual speed information, and for generating a third signal containing information indicating a difference between the reference speed and the actual speed. An integrating component integrates the third signal and generates a fourth signal representing the integrated third signal. The fourth signal may augment a voltage control signal in a voltage-based control circuit or may augment a flux-producing component of a current control signal in a current-based control circuit. The electric motor control circuit may include multiple braking mechanisms for use in different modes of operation.
