Stator for brushless external-rotor motor and method of manufacturing thereof

Abstract

A stator for a brushless external-rotor motor. The stator includes a stator core; a winding; and an end insulator. The stator core includes a yoke part and a tooth part which are separated. The tooth part includes a clamping part. The tooth part is formed by overlapping a plurality of silicon-steel sheets. The end insulator is sleeved on the tooth part. The winding is wound on the end insulator. The yoke part is formed by molding permeability magnetic material and includes a mounting hole in a center. A plurality of lug bosses protrudes at intervals on an outer side of the yoke par. A clamping groove is formed between two connected lug bosses. The clamping part of the tooth part is nested in the clamping groove.
