摘要：A motor having a cooling structure includes a rotor fixed to a rotatable motor shaft, a rotor coil formed adjacent the rotor, a coil protection cover disposed adjacent the rotor coil, mounted in the motor shaft, and having a coolant chamber filled with a coolant. The motor further includes a stator fixed adjacent an exterior circumference of the rotor and may include a cover in which one end portion of the motor shaft is rotatably penetrated having a cooling pin at an internal side surface opposite one side surface of the coil protection cover. The coolant filled in the coolant chamber of the coil protection cover receives heat generated in the rotor coil, and, by effectively emitting the heat to the outside through the cooling pin formed in a rear cover, durability of the entire motor can be improved, and failure of peripheral parts can be prevented.
