Abstract
A motor with a heat dissipating assembly includes a hollow block, a stator fixedly mounted in the block and a rotor rotatably mounted in the stator. A first gap is formed between the block and the stator. A second gap is formed between the stator and the rotor. Multiple through holes are longitudinally defined in the rotor. A stator separator is mounted under the rotor. A groove is defined in the stator separator and communicates with a casing. An air current formed by the rotating rotor flows into the casing through the stator, rotor and the stator separator to form a closed circuit in the motor for dissipating heat. A casing is mounted around the motor and a cooling fan is mounted on the top of the casing to generate an air current to dissipate heat from the outer periphery of the motor.
