A vehicle drive device includes a first bearing that supports a second rotary member on a first rotary member so the second member is rotatable relative to the first, and a second bearing that supports the first rotary member on a case so that it is rotatable relative to the case. The first rotary member has a support outer peripheral surface that faces an outer side, and a first radial support surface that faces one side. The second rotary member has a support inner peripheral surface that faces an inner side. A support of the case has a second radial support surface that faces the first. The first bearing is arranged between the support peripheral surfaces. The second bearing is arranged between the radial support surfaces. The first bearing is arranged on the inner side with respect to a rotor at a position where the first bearing overlaps the rotor.

The present disclosure relates to the field of servos, and in particular to a high-precision miniature servo with a new variable reluctance and improved motor positioning. Compared with conventional variable reluctances, the variable reluctance of the present disclosure has a longer service life, is lower in cost and is easier to machine. The motor component is directly assembled on the housing, so that the cost and space are saved, and the difficulty in mounting and positioning a miniature motor is mainly solved. A motor brush piece and the Ball element are directly machined on a PCBA circuit board, so that the problem on the difficulty and cost control of the conventional machining technology is solved.

A scooter motor includes a stator unit, a rotor unit and a brake unit. The stator unit is fixedly mounted on the fixed shaft of the motor, and the rotor unit is rotatably mounted on the fixed shaft. The brake unit includes a friction plate component and an electromagnetic clutch component. The electromagnetic clutch component is configured to drive the friction plate component to press to brake. According to the embodiment of the present invention, the scooter motor drives the rotor unit to rotate by the cooperation between the stator unit and the rotor unit to drive the scooter, additionally, the stator unit controls the rotation of the rotor unit by using the friction plate component and the electromagnetic clutch component to realize the braking of the scooter.

The present invention relates to a generator input shaft assembly comprising a generator input shaft (160) arranged to receive a drive input to the generator, and a disconnect input shaft (120) arranged to deliver a drive input from the generator input shaft to a disconnectable drive transfer means (116). The disconnectable drive transfer means is configured to transfer rotational drive from the generator input shaft assembly to a rotor (110) of the generator. The generator input shaft assembly is configured such that the generator input shaft can: float axially relative to the disconnect input shaft and/or drive the disconnect input shaft with an axis of rotation of the generator input shaft non-parallel to an axis of rotation of the disconnect input shaft, so as to compensate for a misaligned input to the generator input shaft. Other aspects of the invention relate to a generator and a system comprising the generator input shaft assembly.
