摘要： A stator for an electric motor has a laminated stator core 10 formed from a plurality of stacked laminations, and a stator winding formed from a plurality of coils 20 wound on bobbins 30. The stator core 10 has a plurality of teeth 40 which extend radially and alternately spaced between and connected to circumferentially extending yokes 50. The yokes and the teeth are separately formed with each yoke 50 being a stack of yoke laminations 12 and each tooth 40 being a stack of tooth laminations 14. The teeth 40 are inserted through the bobbins 30 and arranged in a cylindrical form with each tooth 40 extending radially. Yokes 50 are then fixed between radially outer ends 144 of adjacent teeth to complete the radially outer portion of the stator core. Each tooth 40 has a radial location surface 144b which contacts an inner surface of the adjacent yokes 50. The yokes 50 and teeth 40 are fixed together by welding the yokes 50 to the outer ends 144 of the teeth 40.

摘要： An electric motor has a stator and a rotor. The stator has a housing with inlets and outlets. The rotor has a shaft, a rotor core and a commutator. A fan is fixed to the rotor. An end cap is fitted to the housing to close a first end of the housing and support electrical components, including brush gear. The brush gear includes two brush assemblies, each comprising a brush for making sliding electrical contact with the commutator and a brush guidance mechanism for resiliently urging the brush into contact with the commutator. The brush assemblies are accommodated in compartments of the end cap. Each compartment has vents on an axially facing side thereof and openings in a transverse wall thereof. An air guide guides a part of the airflow generated by the fan exiting from at least one of the outlets of the housing to flow into the compartments via the openings and exit the compartments via the vents to cool the brushes.
