A motor includes a rotor, a frame accommodating the rotor, a cover provided at one of two ends of the frame in a direction of a rotor axis, an internal space formed by the frame and the cover and a partition part partitioning the internal space into two spaces. The partition part includes an insertion portion. A part of the cover is inserted into the insertion portion.

A brush holder apparatus includes a stationary support member having at least one groove and a fork electrical connector. A brush retainment member has a brush restraint apparatus having a plunger brush restraint configured to restrain a brush from sliding within the brush retainment member by pressing it against the brush retainment member. The brush retainment member has at least one rail configured to slide along the at least one groove, and a knife electrical connector configured to mate with the fork electrical connector. The brush retainment member is configured to be releasably affixed to the stationary support member. The stationary support member is configured for electrical connection to a collector mount, and the brush retainment member is configured to retain at least one brush.

The present invention provides a valve timing control device that can suppress a leakage of noise to the outside of the device and can improve reliability without needlessly increasing the volume occupied by the device. There is provided a valve timing control device for an internal combustion engine, including a driving rotary body to which rotational force from a crankshaft is transmitted, a driven rotary body, an intermediate rotary body, a speed reduction mechanism, an electric motor, and a housing, wherein: the electric motor rotates relative to the camshaft and the housing; the valve timing control device further includes a current application switching mechanism which is provided inside the housing and which includes brushes to switch current application to a coil of the electric motor, and feeding mechanisms which are provided between the housing and an external device and which include brushes to apply a current from the external device to the current application switching mechanism; electromagnetic noise emission suppression means is provided on the power supply side of the brushes of the feeding mechanisms; and the brushes of these mechanisms are disposed apart from the rotational axis of the camshaft by substantially the same distance.

The invention relates mainly to an assembly comprising a brush cage and a spiral spring (36), the spiral spring (36) comprising an axis (Y), a wound part (37) wound about the axis (Y) and an arm (39) extending from one end of the wound part (37), the brush cage comprising at least one lateral wall provided with an opening for the passage of the arm (39) through the lateral wall so that one end of the arm (39) can press against at least part of an end face of a brush, wherein the arm (39) comprises a first portion (391) of which the width (L5) measured along the axis (Y) is different from the width (L6) of the wound part (37) measured along the axis (Y) of the spiral spring (36).

A gear motor assembly includes a motor and a gearbox connected together. The motor includes a stator and a rotor. The stator has a housing, magnets attached to the housing, and brushes. The rotor includes a shaft with a rotor core, a commutator, a sleeve, a bushing and a worm mounted thereon. The bushing is slidably located between the commutator and worm. The sleeve is located between the commutator and the bushing. The rotor is balanced with the worm fix to the shaft. The gearbox includes a casing having an opening, and a worm gear received in the casing. The brushes of the motor are mounted in the casing. The shaft has a first end that extends into the gearbox. The bushing is fixed in the casing via a bushing seat.

On one side of a worm wheel (46) in an axial direction, first thinned portions (46e) recessed toward the other side of the worm wheel (46) in the axial direction are arranged. Further, on the one side of the worm wheel (46) in the axial direction, reinforcing portions (46h) reinforcing areas between the first thinned portions (46e) and tooth portions (45) of the worm wheel (46) are arranged. Therefore, it is possible to reduce a weight of the worm wheel (46) and to suppress occurrence of distortion of the tooth portions (45) by the first thinned portions (46e). In addition, it is possible to sufficiently increase the strength of the worm wheel (46) in the vicinity of the tooth portions (45) by the reinforcing portions (46h).

An electric motor for driving a motor vehicle component, such as a fan motor for cooling cooling water, has a thermal fuse with a contact spring. The contact spring has attached ends that are connected to a conducting path section between which an interruption point is formed. The springy ends of the contact spring are in soldered contact with each other in a spring-biased manner. The thermal fuse is a fuse module with a plastic support in which the conducting path sections are partially embedded in such a way that the contact spring lies in a window opening in the support. Terminals of the conducting path sections protrude from the plastic support.
