摘要： The present disclosure relates to a motor. The motor can include a stator defining an interior space, a rotor disposed in the interior space of the stator. The rotor can include a body defining a structure and a plurality of magnets disposed in the plurality of cavities. In some embodiments, the structure defines a plurality of cavities in the body of the rotor, the plurality of cavities includes at least a first cavity and a second cavity, the first cavity is spaced radially outward from the second cavity, and a thickness of the first cavity is larger than a thickness of the second cavity. In some embodiments, at least some of the cavities of the plurality of cavities have a magnet from the plurality of magnets disposed therein.

摘要： A system for controlling plurality of synchronous motors connected in parallel including a motor drive, current sensor, and plurality of synchronous motors connected in parallel to the motor drive. The synchronous motors connected to the motor drive can include the same size and power rating to allow synchronous operation and have similar load capacity. Further, the system can operate with substantially similar loads on each of the plurality of synchronous motors. The motor drive can be a variable speed drive using vector control and a closed loop current controller to control the motors. The motor drive can be a variable frequency drive using scalar control and open loop controller to control the motors. The motor drive controls the plurality of synchronous motors by maintaining net active power and net active power, and by rejecting power perturbations, at the common node.

摘要： A rotor for an electric motor is provided. The rotor is constructed of a stack of first and second laminations. The laminations include segments and insulated regions between the segments. The first laminations include interconnections such that the first laminations are self-supporting. The second laminations are affixed to the first laminations to support the segments of the second laminations.

摘要： An electrical motor is provided to reduce torque ripple. Torque ripple is a variation in torque output as the rotor rotates. The motor has a stator and a rotor. The stator slots are used for windings. The rotor slots define a plurality of poles. The number of slots in the stator are equal to the number of slots in the rotor.

摘要： An industrial electrical machine includes a stator; a rotor in magnetic communication with the stator; a plurality of windings disposed in the rotor and/or the stator; and an embedded solid state controller. The solid state controller is operative to control the operation of the industrial electrical machine. The solid state controller includes a power semiconductor switching device coupled to the plurality of windings, and includes a communication interface. The power semiconductor switching device is operative to provide switching during operation of the industrial electrical machine, and is operative to turn the electrical machine on and to turn the electrical machine off in response to a control input received by the communication interface.
