发明名称 Electric motors having EMI reducing circuits and methods therefor
摘要 An electric motor having a circuit for reducing electromagnetic interference (EMI) includes a field stack such as a stator, an armature including a shaft, a commutator mounted on the shaft, and an armature core electrically connected to the commutator, whereby the armature core is rotatably mounted within the field stack. The electric motor includes a brush assembly adapted to deliver electrical power to the commutator. The circuit includes a delta capacitor network and a conductive lead electrically interconnecting the delta capacitor network and the brush assembly. In one embodiment, the circuit includes motor field windings or coils, and a power source electrically interconnectable with the delta capacitor network and the motor field windings. In one embodiment, the motor is a universal motor.
