ENGINE COOLING SYSTEM AND MOTOR THEREFOR
First Claim
1. An engine cooling system comprising:
- an engine;
a coolant tank;
a radiator;
a plurality of connecting pipes connecting the engine, the coolant tank and the radiator to form a loop; and
a cooling module for cooling the radiator, the cooling module comprises a motor and an impeller driven by the motor, the motor comprising a stator and a rotor rotatably mounted confronting the stator, the stator forming 2P stator poles and wherein P is a positive integer, the rotor comprising a shaft, a rotor core fitted to the shaft, and a plurality of windings wound around the rotor core, the rotor core comprising n teeth and forming n winding slots between the teeth, wherein the number of the winding slots n is a multiple of the number of the stator poles 2P, at least one slot having a radial depth less than that of at least one of the other slots, the windings comprising a plurality of coils, and each of the coils is wound about n/2P teeth.

Abstract
An engine cooling system includes an engine, a coolant tank, a radiator, a cooling module for cooling the radiator, and connecting pipes connecting the engine, the coolant tank and the radiator to form a loop. The cooling module includes a motor and an impeller. The motor includes a stator and a rotor. The stator forms 2P stator poles, wherein P is a positive integer. The rotor includes a shaft, a rotor core, and windings wound around the rotor core. The rotor core includes n teeth and forms n winding slots between the teeth. A slot has a radial depth less than one of the other slots. The number of winding slots n is a multiple of the number of stator poles. The windings includes coils each of which is wound about n/2P teeth.
