摘要： A drive unit has a first electric machine with a first rotor mounted to rotate about a rotation axis. A first stator is coaxially arranged and has a stator core lamination packet with a first coil end forming a first switching side and a second coil end forming a first counter-switching side. A second electric machine is mounted axially close to the first electric machine and has a rotatably mounted second rotor that extends in the axial direction around the rotation axis. A second stator is mounted coaxially with the second rotor and has a second stator core lamination packet with second stator coils having a third coil end forming a second counter-switching side and a fourth coil end forming a second switching side. A housing accommodates the first and second machines, where the first counter-switching side and the second counter-switching side face one another in the axial direction.

摘要： An electric motor comprises a stator presenting a first surface. A rotor is rotatable relative to the stator. The rotor presents a rotor raceway disposed in spaced relationship with the first surface of the stator. The first surface of the stator defines a plurality of slots in spaced relationship with one another to define a plurality of spaced teeth between the slots. At least one electrical conductor is disposed in each of the slots and configured to selectively create a moving magnetic field for acting upon the rotor for providing rotational movement of the rotor. A portion of the at least one electrical conductor extends substantially into radial alignment with, or past the first surface of the stator to at least partially define a stator raceway of the stator for engaging the rotor raceway of the rotor during relative radial movement between the rotor and the stator.

摘要： A vehicle includes a battery, an electric machine, a thermistor, and a controller. The electric machine is configured to draw electrical power from the battery to propel the vehicle. The electric machine has a rotor and a stator. The stator has a core, interconnected hairpins, and a neutral bar. The core defines slots. The interconnected hairpin windings are arranged within the slots and are arranged to form a plurality of electrical phases. The neutral bar is connected to each of the electrical phases and defines an orifice. The thermistor is disposed within the orifice and is configured to sense a temperature of the electric machine. The controller is programmed to control a power output of the electric machine based on the temperature of the electric machine.

摘要： An axial flux motor includes a housing; a drive shaft disposed within the housing; at least one rotor; and at least one stator. The at least one rotor includes a diametrically-magnetized single pole pair magnetic ring having a rotor aperture defined through the center of the magnetic ring, where the drive shaft extends through the rotor aperture and where the at least one rotor is fixed to the drive shaft. The at least one stator includes a number of conductive windings and a stator aperture, where the drive shaft extends through the stator aperture and where the drive shaft is rotatable within the aperture. The at least one stator is configured to generate an axial magnetic field that causes the at least one rotor to rotate, thereby rotating the drive shaft.

摘要： A vibration motor includes a movable portion and a stationary portion including a housing with a housing cylindrical portion, a housing lid at an end of the housing cylindrical portion, and adhesive. The housing lid includes a lid body portion covering an opening on one side of the housing cylindrical portion, and a lid fixing portion protruding from the lid body portion to another side and inside the housing cylindrical portion. The adhesive is in at least a portion of a bonding region between the housing cylindrical portion and the lid fixing portion in a radial direction. The housing cylindrical portion includes a cutout portion recessed from an end surface on one side of the housing cylindrical portion to the other side and penetrating the housing cylindrical portion in the radial direction. A portion of the bonding region is exposed to an outside of the housing through the cutout portion.

摘要： A brushless motor includes a motor body, a bracket, and a power supply structure for supplying power to the motor body through a through hole in the bracket. The motor body includes a stator having a core with teeth and a coil formed of a winding wound around the teeth. The power supply structure includes, for each phase, a winding pair including a first lead portion and a second lead portion of the winding, a guide part that guides the winding pair, and a connector part where the lead portions are electrically connected. The winding pair includes a first portion guided by the ide part and a second portion formed by bending the winding pair at an axially outer end of the first portion along a surface of the bracket. The first portion passes through the through hole in the axial direction. The second portion extends to the connector part.
