Abstract: An electronic assembly with RFI shielding including a circuit board, a high frequency electromagnetic radiation device, and a shielding cover is provided. The circuit board includes a connector. The high frequency electromagnetic radiation device is detachably inserted to the connector of the circuit board to be electrically connected with the circuit board. The shielding cover is detachably assembled to the connector to be opened or closed relative to the circuit board. The shielding cover shields high frequency radiation generated by the high frequency electromagnetic radiation device when the shielding cover is in a closed state, and at least a portion of the shielding cover contacts the circuit board in the closed state, and the shielding cover is electrically connected to a grounding portion of the circuit board via the connector.

Abstract: A rail brush assembly for an electric motor having a commutator, comprises a brush, a spring, a pair of rails and at least one detent for retaining the brush on the rails. The brush has a groove on each of a pair of opposite sides. The rails are disposed in the grooves for guiding the brush to the commutator with the brush being freely slidable along the rails within a predetermined range of motion. The spring is arranged to urge the brush along the rails towards the commutator of the motor and is attached to an end of the brush remote from the commutator. The detent is formed between the spring and at least one rail to limit the range of movement of the brush along the rails.

Abstract: The motor of an anti-lock braking system comprises a stator having six stator poles and a rotor with a rotor core having nine teeth. The rotor is rotatably mounted to the stator with the rotor core confronting the stator poles. Rotor windings are wound about the teeth and electrically connect to a commutator fixed to a rotor shaft. A bearing is fixed onto one end of the rotor shaft. Pump pistons radially attach to the bearing. The mechanical centreline of the bearing is offset from the rotational axis of the rotor shaft so that the pistons are driven by the bearing when the rotor turns. The windings comprise a plurality of concentrated coils so that the coils do not overlap with each other. The axial length of the motor is thus reduced.
