A new permanent magnet motor

The present invention discloses a novel permanent magnet motor, comprising a stator and a rotor, said stator core comprising a base and a base wall, provided with winding core, the stator coil is opened seat is fixed by shrink sink, the cooling water pass, both ends of the base end is connected by a bolt and end cap, said rotor shaft comprising a magnetically permeable material employed in the shaft and the mounting surface of the magnet, the magnet casing has non-magnetic materials used jacket, using both sides of the shaft has a non-magnetic material fixed end platen, platen side end plate having a smooth surface, a plurality of segment pieces on the other end side of the platen; machine of the present invention uses an enhanced cooling water cooling to cool the stator holder, using an open cooling air to cool the rotor axially, the motor running in the permissible temperature range, significantly enhanced cooling performance of the motor, improve performance and reliability of the motor.
