Abstract: A motor includes a rotary shaft having at least one spray hole for spraying a cooling fluid, a rotor installed on the rotary shaft, and a stator surrounding an outer circumference of the rotor, wherein the rotor includes a plurality of rotor blocks arranged on an outer circumference of the rotary shaft. Each of the rotor blocks may include a magnet installed at a rotor core and a cooling guide may be disposed between a pair of the plurality of rotor blocks and form a spray flow path for guiding a cooling fluid that has passed through the spray hole to be sprayed in a direction toward an inner circumference of the stator.
