Pole Slot Matching Method of Reluctance Resolver

Abstract

The invention discloses a pole slot matching method of a reluctance rotary transformer. The reluctance rotary transformer includes a stator, a rotor and a winding. The excitation winding is wound on the stator in reverse series by slots, and the number of turns of the signal winding changes sinusoidally. wound on the stator. In order to explore the pole slot matching method of the resolver, the present invention introduces the number of pole pairs of the signal winding, and calculates the output induced electromotive force of the signal winding according to the working principle of the sinusoidal distributed winding reluctance type resolver, and obtains the number of stator teeth, the number of pole pairs of the signal winding and the rotor The relationship between pole pairs. According to the established relationship, rotors with different pole pairs can share the same stator and signal winding form, the same rotor can be used on different stators, and a stator can be matched with any number of rotor pole pairs, which is beneficial to resolver products The serialization of the resolver shortens the design time of the resolver, increases the types of the resolver, and meets the needs of various practical applications.

Description

technical field [0001] The invention relates to the field of reluctance rotary transformers, in particular to a pole slot matching method of a reluctance rotary transformer. Background technique [0002] Reluctance resolvers are widely used in integrated starter generators, traction motors, and permanent magnet motors due to their simple structure, light size, high reliability, high precision, high temperature resistance, moisture resistance, and strong anti-seismic and anti-interference capabilities. Angle position sensor of vehicle equipment, etc. Permanent magnet motors can be designed with different numbers of pole pairs according to actual usage. However, for permanent magnet motors with different numbers of pole pairs, there are not many reluctance resolvers to choose from on the market. For example, permanent magnet motors with 12 slots and 10 poles are widely used in modern industrial applications due to their outstanding performance. However, there is no universa...
