The present invention discloses a driver cabinet structure, including an upper driver cabinet, a lower driver cabinet, a motor front-end cover and a motor brush rack plate, wherein the motor front-end cover is disposed on the lower driver cabinet; the motor front-end cover is provided with the motor brush rack plate thereon and screw holes on a lateral surface; the motor brush rack plate is provided with brush holders thereon and a through hole in the center; front and rear ends of each of the brush holders are both open and intercommunicated; a limit step is disposed in the through hole; lug bosses are disposed on the limit step; and the lower driver cabinet, the motor front-end cover, the motor brush rack plate and the brush holders are integrally formed. According to the driver cabinet structure provided by the present invention, the coupling precision and product consistency of the driver cabinet are improved, the assembly procedures are reduced, and the cost is saved; the two ends of each of the brush holders are open and in assembly, a rotor is pressed in first and then a carbon brush is assembled, thus preventing the damage of the carbon brush; the provided screw holes are coupled with screws to reinforce a rotor bearing, so that the bearing is prevented from axially moving; and with a damping member, the self-locking function of a driver is improved, and thus the problems of high cost and easy damage of an existing steep-lead driver having the self-locking function are solved.

A brush device includes a holder, a brush, a choke coil, and a terminal member. The holder includes a base extending in a direction orthogonal to an axial direction of an armature. The choke coil includes a core and a winding. The core extends in the axial direction of the armature and includes a first end surface in a longitudinal direction faced toward the base of the holder and a second end surface in the longitudinal direction located at a side opposite to the first end surface. The terminal member is coupled to the holder and connected to the winding. The terminal member includes a contact portion that is in contact with the second end surface of the core.

An electric working machine includes a motor, a circuit board having capacitors and choke coils for noise reduction, and a fixing tool for fixing the circuit board to a portion of a case of the motor including motor terminals for power feed. The circuit board includes input terminal members to receive an externally supplied driving power, and a ground connection member electrically coupled to the portion of the case. The capacitors couple the input terminal members to the ground connection member. The choke coils couple the input terminal members to the motor terminals. The ground connection member is arranged in a certain area of the circuit board, which is one of areas on the circuit board defined by dividing the circuit board with a straight line crossing a rotational shaft and is an area where the input terminal members are located. The capacitors are mounted in the certain area.

A motor transmission connection arrangement, in particular for use in vehicles, can comprise a motor pot, a brush holder, and a transmission housing. The motor pot, the brush holder and the transmission housing are pluggable to connect with one another, and the motor pot can include a number of centering surfaces, whereby the motor pot with respectively one of the centering surfaces comes into contact both with the brush holder as well as with the transmission housing, when the motor pot, the brush holder and the transmission housing are plugged into one another. The brush holder and the transmission housing can be concentrically oriented to the motor pot. In addition, the present disclosure refers to a sunroof for a vehicle with a motor transmission connection arrangement of this type as well as a vehicle with such a motor transmission connection arrangement.

A DC motor includes: a brush configured to be connectable with the commutator; a first terminal attached to the brush; a second terminal disposed at a position away from the first terminal, the second terminal being configured to be connectable with an external terminal; a bracket to which the first terminal and the second terminal are attached; and a positive temperature coefficient (PTC) thermistor disposed between the first terminal and the second terminal, the PTC thermistor including a first electrode bonded to the first terminal and a second electrode bonded to the second terminal, wherein the PTC thermistor is a surface-mount type thermistor in which the first electrode and the second electrode are exposed on one surface side and wherein, on the one surface side of the PTC thermistor, the first electrode faces the first terminal and the second electrode faces the second terminal.
