摘要： A motor control system is provided. The system includes an inverter that adjusts a stator current applied to a stator coil of a wound-rotor drive motor and a rotor current applied to a rotor coil of the drive motor. When an abnormal starting of the drive motor is detected and a movement of the vehicle is restricted by electronic parking brakes (EPB), a motor controller adjusts the rotor current through the inverter to cancel an abnormal starting torque caused by the abnormal starting.

摘要： A stator of a driving motor and a coil connection assembly of the stator is provided. The coil connection assembly of the stator of the driving motor includes a coil connection portion that is drawn from a stator coil wound on a stator core in multiple strands. A ring terminal is electrically connected to the coil connection portion. The ring terminal includes a cylindrical connection compressing portion fitted with multiple strands of coils of the coil connection portion that are compressed by a set pressing force and connected with the coils. A bolt fixing portion is integrally formed with the connection compressing portion and has a engagement bore configured to engage a bolt. Conductive protrusions that penetrate an insulating film of coils of the coil connection portion by the set pressing force are formed on the inner periphery of the connection compressing portion.

摘要： A stator of an interior permanent magnet synchronous motor is provided. The stator spaced apart from a rotor by a predetermined gap within an interior permanent magnet synchronous motor includes a stator tooth that is circumferentially spaced apart by a predetermined distance while interposing a slot therebetween that corresponds to an exterior diameter surface of the rotor. Additionally, a stator shoe is formed at an end of the stator tooth and includes an interior diameter surface of a predetermined diameter that faces the exterior diameter surface of the rotor. A cross point between a circle has a diameter of (interior diameter of the stator shoe×1.0287×24/slot number) mm and the stator tooth is a tooth end start point of the stator tooth.
