Processing method and device of alternating-current permanent-magnet servo motor stator

Abstract

The invention relates to a processing method and a device of an alternating-current permanent-magnet servo motor stator. The method of the invention comprises the following steps that: 1) the processing device is arranged on a spindle of a machine tool by a taper shank, a machine base is heated, and a stator iron core is sheathed into the machine base; 2) the stator is arranged on an expanding sleeve to guarantee that the end surface of the iron core is stuck with the positioning surface of the expanding sleeve tightly; 3) the machine tool is started, spigots at the two ends of the processing machine base is processed, a screw is screwed tightly, and the expanding sleeve is expanded tightly; and 4) the screw is loosened, the stator is taken down from a clamp, aluminum skimmings on the stator are blown cleanly by compressed air. The invention solves the problem that the conventional technique influences the concentricity of the stator due to the factors of the deformation of the machine base and the like, and guarantees the concentricity of an inner hole of the stator iron core and the spigots of the machine base, thus achieving the purpose of reducing the location torque of a motor and reducing the vibration and noise of the motor.

Description

technical field [0001] The invention relates to a motor, in particular to a method and device for processing a stator of an AC permanent magnet servo motor. Background technique [0002] At present, the AC permanent magnet servo motor is widely used in numerical control equipment and automatic control equipment due to its high positioning accuracy and quick response; the main reason for affecting the positioning accuracy of the motor is the large positioning torque of the motor. [0003] The machining of the motor stator usually finishes the machine base first, and then presses or shrinks the stator core into the machine base. This is often due to deformation in the process of processing, which causes the inner hole of the iron core to be out of concentricity with the mouth of the machine base. Especially for the thin-walled frame, the frame is more likely to be deformed during processing; and when the iron core is pressed into the frame, it is impossible to ensure that the ...
