Electric motor i.e. direct current motor, for use in electric hand tool device, has bearing bracket and stator including protrusion, which engages into recess of another bearing bracket and stator in assembled condition of bearing bracket

摘要

#CMT# #/CMT# The motor has a commutator, a stator and a rotor for driving a drive shaft. A cup shaped bearing bracket (10) is provided for storage of the drive shaft. The bearing bracket is made of plastic and fixed at the stator. The bearing bracket and the stator have a protrusion (26), which engages in a recess of another bearing bracket and stator in an assembled condition of the bearing bracket in a locking manner. The protrusion has a profile of harpoon. The bearing bracket is provided at the stator in the commutator side. #CMT#USE : #/CMT# Electric motor i.e. direct current motor, for use in an electric hand tool device (all claimed). #CMT#ADVANTAGE : #/CMT# The bearing bracket is made of plastic, thus manufacturing the bearing bracket as die casting component in a cost effective manner, and meeting the requirements of a safety class system II in accordance with DIN EN 61140and providing sufficient stability for the hand tool device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a front view of a bearing bracket of an electric motor. 10 : Cup shaped bearing bracket 12 : Carbon brush 14 : Cup base 16 : Cup opening 26 : Protrusion.
