摘要: A distributed winding arrangement for an electric motor is provided that reduces brush arcing while reducing the size of the commutator. The electric motor is comprised generally of an armature having a plurality of spaced apart posts defining a plurality of spaced apart winding slots; a stator disposed coaxially with the armature; and a commutator having a plurality of commutator bars, where the number of commutator bars is an integer greater than the number of winding slots but less than twice the number of winding slots provided by the armature.

摘要: A hand-held tool that includes a housing. The housing includes a handle. A tool also includes a motor assembly, a battery assembly and a circuit board. The motor assembly includes a motor, the motor including a rotatable motor output shaft, a motor positive terminal and a motor negative terminal. The motor assembly also includes a first rigid conductive electrical connector having a first end fixed to the motor positive terminal and a second end fixed to the circuit board. The battery assembly includes a battery cell with a battery cell positive terminal and a battery cell negative terminal. The battery assembly further includes a second rigid conductive electrical connector having a first end fixed to the battery cell positive terminal and a second end fixed to the circuit board.

摘要: A power tool including a housing with an electric motor in the housing. The motor has a stator and an armature, the stator having field coils and the armature having an armature shaft on which a commutator is affixed. A pair of brush boxes are located in the housing on opposite sides of the commutator. An orbit mechanism coupled to the armature shaft and a platen is coupled to the orbit mechanism. The field coils comprise a first field coil facing a front of the sander and a second field coil facing a rear of the sander and the brush boxes are rotationally offset from the field coils with respect to a vertical axis of the sander.
