摘要： An electric motor is provided. The rotor includes a rotor shaft, with a bearing rotatably supporting the rotor shaft. A bearing housing is interposed between the bearing and the motor frame assembly. The bearing housing is releasably connected to the motor frame assembly so as to be selectively secured in supporting relationship with the bearing and thereby the rotor. The motor frame assembly includes a circumferentially extending support face. The bearing housing presents a circumferentially extending engagement face which engages the support face when the bearing housing is in the supporting relationship. At least one of the faces is axially tapered to facilitate axial movement of the bearing into the supporting relationship.

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： In a motor control system, a controller generates a single control signal for a motor control unit in a first electric motor and another motor control unit in a second electric motor. The motor control units in the first and second electric motors operate the first and second electric motors at a first rate in response to the control signal being at a first level. The motor control unit in the first electric motor operates the first electric motor at a second rate and the motor control unit in the second electric motor operates the second electric motor at a third rate in response to the control signal being at a second level, the third rate being different than the second rate.
