Abstract:
A motor having improved heat resistance is provided. The motor includes a rotor comprising a rotor core, two or more slots arranged in a circumferential direction of the rotor in the rotor core, two magnets in a plate shape having a thickness in a radial direction of the rotor, and divided and arranged in the circumferential direction in each of the two or more slots, and a spacer for dividing the two magnets; and a stator disposed outside of the rotor in the radial direction with a clearance from the rotor and comprising a stator core having two or more slots wound with one or more winding wires; and the two magnets are separated from each other by the spacer, by a distance which is 10% to 50% of a circumferential length of the slot having the two magnets.
