Abstract

The invention provides a stator assembly and a servo motor with the same, and the stator assembly comprises: a stator tooth iron core, the circumferential surface of which is provided with a first positioning part which extends in the axial direction of the stator tooth iron core, wherein the middle part of the first positioning part protrudes towards the direction far away from the stator tooth iron core relative to the end part of the first positioning part; and a stator yoke iron core, which is arranged on the stator tooth iron core in a sleeving mode, and is provided with a second positioning part matched with the first positioning part, wherein the second positioning part extends in the axial direction of the stator yoke iron core, and the middle of the second positioning part sinks towards the outer side of the stator yoke iron core relative to the end of the second positioning part. According to the invention, the problem that the motor stator is easy to deform in the assembling process in the prior art is solved.

Description

technical field [0001] The invention relates to the field of motor stator design, in particular to a stator assembly and a servo motor having the same. Background technique [0002] At present, the application occasions of servo motors are getting wider and wider, and the performance requirements of servo motors are getting higher and higher, such as high power density, high overload, small size, low cogging torque, low torque ripple, low temperature rise and low cost etc. [0003] In order to increase the power density and facilitate winding, the stator of the prior art adopts such as figure 1 with figure 2 The method for separating the stator teeth and the tooth yoke is shown. The stator tooth core is formed by laminating the teeth core punches, and the stator yoke core is formed by laminating the yoke core punches. The skeleton of the wound wire (that is, the winding) is placed on the teeth of the stator tooth core, and then the stator yoke core is pressed into the st...
