Permanent magnet powered electric hand-tool, e.g. circular hand-saw, has plate with several saliences and arranged on one of ends in axial direction of rotor core

摘要

An electric work-tool as based on a permanent magnet (18) motor in a housing. The stator is mounted on a inner peripheral surface of the housing and the rotor is arranged rotatably in the stator. A plate has several saliences (23a-1) and is arranged on at least one of the ends in an axial direction of the rotor core (19), where an outer diameter (D2) of at least two saliences (23a-1) of the plate is greater than an outer diameter (D1) of the rotor core (19).
