摘要： 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.

摘要： A medical electric tool has a grip portion and a driving portion. The grip portion has a combining protrusion, two combining channels, and a locking device. The combining channels are defined respectively in two sides of the combining protrusion. The locking device is mounted in the combining protrusion and has two locking blocks and two recoil springs. Each locking block has an engaging segment. The engaging segment is formed on one end of the locking block and extends into one of the combining channels. The driving portion is detachably mounted on the combining protrusion on the grip portion and has a bottom face and two engaging ribs. Each engaging rib has an end provided with an engaging hook selectively engaging with the engaging segment of a corresponding one of the locking blocks.
