This disclosure enables an assembly for driving an arm of a windshield wiper of a vehicle. The assembly includes a support structure in a housing that is secured against rotation relative to the housing. The support structure has an opening with a bearing surface, where the opening is configured to receive a boss of a worm wheel such that the bearing surface faces the boss of the worm wheel.

The invention relates to a wiper motor having a housing element connected to an electrical line that has an elastically deformable spring element in an end region projecting out of the housing element, wherein the spring element, in order to form an electrically conductive connection with a counterpart element on the housing element, is movable, with respect to a first, relaxed position of the spring element, into a second, elastically deformed position generating a contact force on the counterpart element.

The present disclosure provides a motor router comprising: an annular body having a first coil guide; and a guide part formed to protrude from the body, and having a second coil guide to which the first coil guide is connected, and thus the present invention reduces the number of parts and has a simplified configuration, thereby providing an advantageous effect of reducing manufacturing processes and manufacturing costs.

A sealed actuator with internal clutching assembly including an output shaft, output detent ring, moving detent ring, and a wave spring, which is fit inside a sealed housing. The moving detent ring is able to move axially to the output shaft and the output detent ring is able to rotate on the output shaft. Intermeshing ramped teeth of these rings are held together by a wave spring and allow the output shaft to rotate and transmit torque of a motor through a main gear operably coupled to an output gear mounted on the output shaft to the outside of the housing. During predetermined high loads, the output and moving detent rings ramped teeth create an axial force that overcomes the load from the wave spring, which allows moving detent ring to disengage and output shaft to rotate freely to help prevent damage to the actuator.

Sloped surfaces are formed on the side surfaces of the permanent magnets in the circumferential direction. The angle θ2 between lines L3 and lines L2 is an electrical angle of 13° or more, said lines L3 connecting outer circumferential corner portions where the sloped surfaces and the outer circumferential surface are connected to each other and the shaft center, said lines L2 connecting the radial direction outermost side of the circumferential side surface of the salient pole and the shaft center.

An electric motor module includes: an electric motor; a printed circuit board; a gear that performs conversion such that an output shaft extends is orthogonal to a rotating shaft of the electric motor; a storage portion that houses at least the electric motor and the gear; and a connector storage portion that houses the connector and attached to an opening of the storage portion. A connection portion between the opening and the connector storage portion is inclined with respect to the rotating shaft on a plane perpendicular to the output shaft. The printed circuit board includes: a first portion parallel to the rotating shaft on the plane; and a second portion extending from one end of the first portion toward the rotating shaft. A connector is disposed at another end of the first portion, and a terminal is disposed in the second portion.

A motor device and a method for producing same are provided. A connector storage unit (33d) and a substrate storage unit (33c) which are provided in a gear case (31) open in a direction (axial direction of output shaft) which intersects the axial direction of an armature shaft. As a result, when assembling a motor device (10), it is possible to store a connector member (60) and a control substrate (50) in the connector storage unit (33d) and the substrate storage unit (33c), which have comparatively large openings, by insertion therein from the same direction.

The invention relates to a geared motor comprising a first brushless electric motor part having a stator, a rotor and a drive shaft, a second part having an output shaft and a reduction gear mechanism and an electronic part. The reduction gear mechanism comprises an output shaft, a worm and a toothed wheel designed to be engaged by the worm and to drive the output shaft in rotation. The geared motor comprises at least one rolling guide bearing disposed on the drive shaft and a multipolar magnet for measuring the position of the rotor. The rolling bearing is disposed between the measurement magnet and the worm such that the electric motor can be controlled depending on the measurement of the position of the rotor.

The present disclosure discloses a modular large spherical tank internal detection device with a self-locking function, and belongs to the technical field of safety detection of large spherical tanks. The detection device includes a transmission group and a detection group. A movable pin is matched with the rotation of a second motor in an unconnected state, so that inner central shafts rotate to realize up-down movement of a detecting instrument in a vertical plane. The movable pin is matched with the rotation of a first motor in a connected state, so that the whole detection device rotates round a central axis of a large spherical tank to realize horizontal circumferential movement of the detecting instrument. All detection of a spherical surface inside the large spherical tank can be completed by combining two types of movement of the detecting instrument.
