Abstract: Disclosed is a rotor permanent magnet apparatus for a driving motor based on temperature distribution. The permanent magnet may enhance coercivity without a substantial decrease in magnetic flux density Br by applying a grain boundary diffusion process (GBDP) of diffusing dysprosium on the surface of the permanent magnet based on the temperature distribution of the permanent magnet.

Abstract: Disclosed is a rotor of a wound rotor synchronous motor. According to an embodiment of the present invention, the rotor of a wound rotor synchronous motor includes a plurality core blocks constituted by rotor cores. Bobbins around which coils are wound are inserted into the core blocks. Each core block is joined to each other. One upper part of one bobbin is extended from a bobbin main body to be joined to another upper part of another bobbin inserted into adjacent core blocks. A molding material is filled in each gap between each core block.

Abstract: PURPOSE: An environment-friendly motor is provided to improve cooling efficiency by using cooling medium for cooling a stator core. CONSTITUTION: A stator core(10) includes a coil(20) and a stator(30). A rotor(60) includes a permanent magnet(50) and a rotor core(40). A motor housing(70) supports the rotor core. A cooling groove(80) is formed in the housing. Cooling medium flows along a cooling pass(90). A sealing layer(95) is formed between the stator core and the cooling groove.
