Abstract

The invention provides an outer rotor motor for a sewing machine, and particularly relates to the technical field of sewing machine manufacturing. The outer rotor motor for the sewing machine comprises a sewing machine head, a wiring stator, a main shaft and an outer rotor, the motor also comprises a wiring encoder, a rotor and a limiting sleeve. The wiring stator is fixed on the limiting sleeve;the outer rotor is sleeved and fixed on the main shaft; the rotor is sleeved and fixed on the main shaft on one side, close to the sewing machine head, of the wiring stator; magnetic steel is fixedlyinstalled on the rotor, the wiring encoder is provided with a first Hall, a second Hall, a third Hall and a positioning Hall, the positioning Hall and the magnetic steel are oppositely arranged in a matched mode, and the first Hall, the second Hall and the third Hall are arranged between the wiring stator and the outer rotor. The outer rotor motor is divided into the stator module and the outer rotor module, high assembly efficiency is achieved, and under the same cost, the outer rotor motor is higher in efficiency and larger in torsion compared with an inner rotor motor, and has a high application prospect.

Description

technical field [0001] This application proposes an outer rotor motor for sewing machines, specifically relating to the technical field of sewing machine manufacturing. Background technique [0002] Existing inner rotor motors need to increase the thickness of winding coils and magnetic steel for excessive thickness, while outer rotor motors have higher torque at low speed than inner rotor motors at the same cost. At present, although the inner rotor servo motor we use can achieve higher efficiency, the outer rotor can achieve higher efficiency, and the inner rotor servo motor needs to be improved in terms of motor intelligent control. Contents of the invention [0003] In view of the deficiencies in the existing motor technology mentioned above, the technical problem to be solved in this application is to provide an outer rotor motor for sewing machines, so as to achieve the purpose of intelligent control of the sewing machine motor. [0004] The outer rotor motor for se...
