Title:
MOTOR MODULE AND ELECTRIC TOOL APPLYING SAME
Document Type and Number:
WIPO Patent Application WO/2022/105217
Kind Code:
A1
Abstract:
A motor module and an electric tool applying same. The motor module comprises a motor, a cooling fan mounted on a rotor in the motor, and a control circuit board used for controlling the motor to operate, wherein the cooling fan is located between the motor and an impact output module. By providing the cooling fan on the front end of the motor and the control circuit board on the rear end of the motor, the rotating shaft of the motor does not need to pass through the control circuit board. Therefore, there is no need to reserve a through hole for the rotating shaft to pass through in the control circuit board, the area of the control circuit board can be larger, and electronic components mounted on the control circuit board can be more sparse, so that the heat dissipation effect of the control circuit board is better.
