SPOKE TYPE PERMANENT MAGNET MOTOR

摘要

PURPOSE: A spoke type permanent magnet motor for centering a magnetic flux is provided to reduce demagnetization of a permanent magnet by inserting a magnetic material into the permanent magnet. CONSTITUTION: An inner stator(110) comprises a rotary shaft insertion hole(111) for inserting a rotary shaft, a stator slot(113) radially arranged around the center of the insertion hole, and a stator core(112) radially formed between stator slots. An outer rotor of a spoke type has a rotor core(131) and a permanent magnet(140) radially arranged between the rotor cores. A rotor housing(150) is formed on the outer rotor. A first coupling member is formed on an upper portion and a bottom portion of the rotor housing and is made of a non-magnetic material along a height direction of the outer rotor. A second coupling member is made of a non-magnetic material while passing through the rotor core and the first coupling member.
