Method for manufacturing stator of brushless direct current electric motor, and stator of brushless direct current electric motor manufactured by the method

摘要

Disclosed is a method for manufacturing a stator of a brushless direct current electric motor which can cut down the unit cost of production and improve the B-H property and the core loss property, by forming a band-shaped back yoke by using a silicon steel plate sheet, helically stacking the back yoke, and inserting poles formed by a magnetic iron powder into the inner circumferential surface of the back yoke, and a stator of a brushless direct current electric motor manufactured by the method.
