Abstract
The present invention relates to a motor, a circuit board and an engine cooling module including the motor. The motor includes a stator and a rotor. The stator includes a control module and a heat sink. The control module includes a circuit board and heat generating electronic components mounted on the circuit board. A bottom surface of the circuit board faces the heat sink. The heat generating electronic components are mounted on a top surface of the circuit board. Metal heat conducting members are embedded inside the circuit board at positions corresponding to the heat generating electronic components, and extend along a thickness direction of the circuit board. The heat generated by the heat generating electronic components is conducted from the top surface of the circuit board to the bottom surface of the circuit board. The present invention improves the heat dissipation effect of the motor.
