Magneto resistance type resolver design method

Abstract

The invention discloses a design method of a magnetic reluctance type resolver, the resolver in the method consists of a stator and a rotor, and a group of exciter coils and two groups of output coils are wrapped on teeth of the stator, and the method sequentially comprises four steps of: fixing the relative position, calculating turns ratio of stator, laying wires for the stator regularly and designing the resolver. The resolver designed in the method improves the measurement precision when measuring the location of the rotor of a rotation motor.

Description

technical field [0001] The invention relates to a design method of a reluctance type angle resolver. Background technique [0002] A general resolver has a rotor and a stator, and its rotor is linked with the rotor of the rotating motor, and the resolver indicates the rotor angle of the rotating motor, and after knowing the rotor angle of the rotating motor, it can control Trigger the stator coil of the rotary motor to keep the magnetic field of the stator of the rotary motor perpendicular to the rotor, so that the rotary motor can exert the maximum output efficiency; [0003] However, in the past, resolvers first fixed the number of teeth of the stator and the rotor, and the resolution was the priority when determining the number of teeth of the rotor. Therefore, the phase angle between the rotor and the stator was not fixed and had to be calculated during use, and each The phase angle between the stator and rotor teeth is not necessarily an integer after taking the sine o...

Problems solved by technology

[0003] However, in the past, resolvers first fixed the number of teeth of the stator and the rotor, and the determination of the number of teeth of the rotor was also based on the resolution. Therefore, when using the resolver, the phase angle between the rotor and the stator is not fixed and must be calculated, and each The phase angle between the stator and rotor teeth is not necessarily an integer after taking the sine or cosine value, so the waveform displayed by the oscilloscope is as shown in Figure 1, and it is difficult to maintain accurate sine and cosine waves, resulting in measurement The error in the rotor position of the rotary motor, and most of the industries are now precision oriented, a slight error may cause serious problems, so how to make the angle resolver to measure the rotor position of the rotary motor more precisely is worth developing direction
