摘要： A motor or generator assembly including a motor or generator machine and mounting structure supporting the machine on an appliance is provided. The machine presents an axially extending, radially outermost circumferential face and a pair of axially spaced apart, radially projecting axial margins. The mounting structure includes a pair of at least substantially radially extending plates and a base configured for connection to the appliance. The plates extend at least in part adjacent respective ones of the axial margins and at least in part define a machine-receiving space therebetween. The machine is mounted on the brackets so as to be positioned at least in part in the machine-receiving space. The base is positioned at least substantially radially outside the circumferential face of the machine and presents a pair of axially spaced apart side faces, with each of the plates being secured against a respective one of the side faces.

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： 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 driving waveform to the stator to cause rotation of the rotor; remove the driving waveform from the stator to cause the rotor to coast and eventually stop; apply a stop detection waveform to the stator while the rotor is coasting, wherein the stop detection waveform induces a waveform on the rotor which in turn induces a waveform back to the stator while the rotor is rotating; and monitor the stator to detect a characteristic of the waveform induced back to the stator to detect when the rotor has substantially stopped rotating.

摘要： A motor is provided for use in a machine. The motor includes a segmented stator and a resiliently flexible clip. The stator includes a core having spaced apart arms and a yoke. The arms define an opening therebetween, and the yoke spans the opening. The clip is removably retained on the core so as to apply pressure against each arm toward the yoke such that the arms are retained in contact with the yoke.
