Abstract: A power supply apparatus for a field winding motor. A brush is disposed is a holder. An armature is connected to the brush and disposed in the holder. A slip ring is electrically connected to or disconnected from the brush. A support spring surrounds the brush between the slip ring and the armature. A coil is disposed outside of the holder so as to overlap the support spring and the armature. A first power terminal is connected to the brush and supplies a first driving current. A second power terminal is connected to the coil and supplying a second driving current.

Abstract: Provided is a structure for a slip ring and a brush of a WRSM capable of reducing an axial length of a motor by increasing a contact area between the slip ring and the brush and improving reliability for smoothly implementing performance of the motor by stably supporting a shaft of the motor, the structure including: an inner slip ring combined with a rotation shaft of a motor; a brush disposed at a circumference of the inner slip ring and having a plurality of wrinkles contacting an outer circumferential surface of the inner slip ring formed therein; an outer slip ring disposed at a circumference of the brush and making in contact with the plurality of wrinkles of the brush; and a holder that supports the outer slip ring.

Abstract: Provided is a rotor for a wound-rotor induction motor having anti-spattering members. The rotor includes: a core that includes a base part having a hollow into which a shaft of the rotor is inserted, a plurality of winding parts that extend outward from a circumference of the base part and are spaced a predetermined distance from one another, and a plurality of panel parts that are provided at ends of the winding parts and are wider than the winding parts; coils wound around the winding parts; and anti-spattering members which are in contact with the panel parts and each of which is provided between the pair of winding parts adjacent to each other and prevents the coils adjacent to each other from spattering.

Abstract: An in-wheel motor system capable of maximizing the efficiency in using a wheel space by improving a mounting structure thereof, the in-wheel motor system installed at a wheel of a vehicle to transmit a rotational force including an axle installed at the wheel of the wheel and rotating together with the wheel, an in-wheel motor mounted inside the wheel and provided with a rotor and a stator that are used to generate a rotational force to drive the wheel, the rotor, and the stator disposed to face each other while having an accommodation space thereinbetween, a cycloid decelerator installed at a center of the in-wheel motor, and provided with an output shaft to transmit a rotational force at a reduced speed from the in-wheel motor to the axle and an input shaft that passes through the in-wheel motor and rotates together with the rotor, a disc installed at one end portion of the input shaft that protrudes by passing through the in-wheel motor, and a disc brake configured to provide a braking force by pressing th

Abstract: A mounting structure for an in-wheel motor system is provided. The mounting structure includes the in-wheel motor system installed in a wheel of the vehicle, and a torsion beam axle (TBA) assembly to fix the in-wheel motor system to a vehicle body, wherein a rear portion of a motor housing includes a step portion formed in a stepped manner to have a decreased diameter, and a ring-shaped fastening face vertically arranged from the step portion, and the TBA assembly includes a trailing arm provided with a through hole to surround the step portion of the motor housing, a mount integrated with the trailing arm to fix the trailing arm to a vehicle body, and a plurality of fastening bolts to fix the motor housing to the trailing arm, wherein, when the step portion is fitted and coupled into the through hole, the fastening face closely contacts the trailing arm.
