Description

Motor magnetic winding stator internal diameter detection device

Technical Field

The utility model relates to the technical field of motor assembly, in particular to a motor magnetic winding stator inner diameter detection device.

Background

An electric Motor (motorr) is a device that converts electrical energy into mechanical energy. The magnetic power rotating torque is formed by generating a rotating magnetic field by using an electrified coil (namely a stator winding) and acting on a rotor (such as a squirrel-cage closed aluminum frame). The motors are classified into direct current motors and alternating current motors according to the power supply, and most of the motors in the power system are alternating current motors, and can be synchronous motors or asynchronous motors (the magnetic field rotating speed of a motor stator and the rotating speed of a rotor do not keep synchronous speed). The motor mainly comprises a stator and a rotor, wherein a magnetic pole air gap is arranged between the rotor and the stator so as to ensure that the rotor can freely rotate, in theory, the smaller the magnetic pole air gap is, the better the smaller the magnetic pole air gap is, but the smaller the magnetic pole air gap is, the more difficult the assembly between the motor stator and the motor rotor is, and even the interference between the motor stator and the motor rotor is easy to occur. However, on the other hand, the pole gap cannot be too large, and an excessively wide gap causes new problems such as increased field loss and noise generation.

Therefore, in the process of processing and producing the motor magnetic winding stator, a necessary ring is used for detecting the inner diameter of the stator, however, in the past, the outer side of the stator is clamped by using a hoop, and the inner circle of the stator is detected by using a scale, so that the detection efficiency is low, and the method is not suitable for high-speed production line production.
