MOTOR

摘要

A motor having an improved structure to enhance durability. The motor includes a stator including stator cores and coils wound on the stator cores, a rotor disposed at the inside of the stator and rotated by electromagnetic interaction with the stator, and a motor shaft combined with the rotor so as to be rotated together with the rotor. The rotor includes a plurality of rotor cores arranged to be separated from each other in the circumferential direction of the rotor, a plurality of rotor slots formed between the plurality of rotor cores, a plurality of permanent magnets inserted into the plurality of rotor slots, molding members filling the plurality of rotor slots so as to cover the outer ends of the plurality of permanent magnets, and a plurality of reception holes provided on the plurality of rotor cores so as to be filled with the molding members.
