The rotor is fixed to the rotating shaft. The rotor comprises a rotor core, a first end plate and a second end plate. The first end plate is provided at a first axial end of the rotor core. The second end plate is provided at a second axial end of the rotor core. The fluid cooling system comprises at least one fluid cooling pathway provided internally in the rotor. The at least one fluid cooling pathway is configured to guide cooling fluid through the rotor, and comprises at least one cooling channel and a downstream end plate channel. The at least one cooling channel extends through the rotor core from the first axial end to the second axial end. The downstream end plate channel is fluidically connected to a downstream end of the at least one cooling channel. The downstream end plate channel is restricted radially outwards by a radially outer wall portion. The at least one cooling channel is restricted radially inwards by a radially inner wall portion. A radially innermost position of the radially outer wall portion is arranged in a range about or at or radially inwards of a radially innermost position of a radially inner wall portion.

摘要： A rotor (23) of an electrically driven supercharger compressor (7) includes a rotor centre part (27) and first and second shaft end parts (31, 33). The rotor centre part (27) includes a shaft portion (29) including a permanent magnet (35), and the rotor centre part (27) is configured as a rotating armature of an electric motor (21). The first and second shaft end parts (31, 33) are arranged on opposing end faces of the rotor centre part (27) and are connected to the rotor centre part (27) in a rotationally engaged manner. A basic shape of the first shaft end part (31) and a basic shape of the second shaft end part (33) are mirror-symmetrical to one another.

摘要： A rotor for an axial flux motor with a disk-shaped rotor plate, a plurality of permanent magnets and a holding structure. The disk-shaped rotor plate has a plurality of magnet receptacles, which are distributed in the circumferential direction and introduced into the rotor plate in the axial direction. The magnet receptacles are each defined by four inner side surfaces of the rotor plate. The plurality of permanent magnets are arranged in the magnet receptacles and are each defined by four outer side surfaces. A first groove is introduced into at least one of the inner side surfaces, and a second groove is introduced into at least one of the outer side surfaces. The first and the second groove are arranged and formed in such a way that they jointly form a channel portion in which the holding structure for fixing the permanent magnets in the rotor plate is arranged.

摘要： A method of controlling a motor controlled by a motor controller that includes a complex vector flux regulator (CVλR). The method includes: receiving at a field weakening regulator of the motor controller a modulation index that is a scaled version of an available voltage available to be provided to the motor by a voltage source; comparing the modulation index to a feedback modulation index to produce an error scalar that has a magnitude in a flux domain; determining a final direction (αfinal) of the error scalar in the flux domain; and providing the CVλR with flux commands in the d and q domain based on the error scalar and the direction.
