20220014067 | INTERCONNECTION ARRANGEMENT FOR AN ELECTRICAL MACHINE - An interconnection for an electric machine with hairpin winding, having a plurality of connection pins, the interconnection includes connection conductors that extend over a portion of the circumference in each instance. The interconnection has a carrier that supports the connection conductors and insulates the connection conductors relative to one another. Each connection pin is electrically conductively connected to a connection conductor. The carrier has supporting arms at the outer circumference thereof, in that the supporting arms are inclined relative to a radially extending plane as well as relative to a rotational axis of the electric machine, and the supporting arms have clamping surfaces by which they are clampable between a housing or stator carrier and a bearing shield. | 2022-01-13 |
20220014068 | BUSBAR UNIT FOR MOTOR - A busbar unit that is electrically connected a motor, the motor including a coil wound around a stator, the busbar unit including: a terminal disposed at an upper side of the stator and electrically connected to the coil in an outer region of the coil in a radial direction of the stator; and a holder configured to support the terminal. | 2022-01-13 |
20220014069 | ELECTRIC MOTOR - Insulators each include a plurality of board holding claws projecting from an outer peripheral edge of the circuit board for engaging a plurality of board recesses, the plurality of board holding claws are arranged on the outer peripheral edge of the circuit board such that an interval of board holding claws on a connector-mounted side is smaller than an interval between board holding claws on a counter-connector-mounted side, and a load receiving pin, which receives a radial load, projects at a counter-connector-mounted position, which is opposite to a mounted position of a connector. | 2022-01-13 |
20220014070 | MOTOR AND BRUSH HOUSING PART - A motor includes a commutator, a brush, a first spring, a second spring, and a holder. The brush is configured to come into contact with the commutator to be electrically connected to the commutator. The first spring is configured to push the brush along the first direction toward the commutator. The second spring pushes the brush along a second direction intersecting the first direction. The holder is disposed such that the brush is located between the holder and the second spring in the second direction. The holder holds the brush between the holder and the second spring. | 2022-01-13 |
