The present invention relates to an electric motor and an electric tool equipped with the electric motor. The electric motor includes a rotor, a stator, a coil module wound around the stator, a Hall unit and a wiring circuit unit. The Hall unit includes a Hall circuit board disposed around a rotating shaft of the rotor, and a Hall module for sensing rotation of the rotor. The wiring circuit unit is independent of the Hall circuit board and includes a three-phase power source interface. The wiring circuit unit electrically connects coils of the coil module to the power source interfaces respectively by groups. By separately disposing the Hall unit and the wiring circuit unit independently, a volume of the Hall circuit board can be reduced, and an area blocking an airflow path of a heat dissipation unit can be reduced, so heat dissipation effect of the electric motor and the electric tool can be improved.

A torque control device for an electrical tool has a switching circuit, a voltage detecting circuit, a torque detecting circuit and a processor. The switching circuit connects between a motor of the electrical tool and a DC voltage source. The voltage detecting circuit detects voltage or current variation of the motor. The torque detecting circuit based on the detected voltage or current variation data outputs an actual torque value of the motor. The processor compares the actual torque value with a default value to determine whether actual torque is greater than the default. If so, the switching circuit is turned off by the processor to prevent the motor from being damaged.
