Motor rotation transformer intelligent identification system and control method thereof

Abstract

The invention discloses a motor rotation transformer intelligent identification system and a control method thereof. The system comprises a motor rotation transformer module, a rotation transformer resolving chip, a first amplifying circuit, a second amplifying circuit, and a controller module. The motor rotation transformer module outputs sine and cosine signals to the second amplifying circuit. The second amplifying circuit carries out signal amplifying processing on the sine and cosine signals so as to output a first sine signal and a first cosine signal. The rotation transformer resolving chip collects the first sine signal and the first cosine signal and outputs a group of excitation signals. The first amplifying circuit carries out signal amplifying processing on the group of excitation signals and sends the excitation signals which are subjected to amplifying processing to the motor rotation transformer module. The controller module collects the excitation signals which are subjected to amplifying processing and collects the sine and cosine signals, the rotation transformer change of the motor rotation transformer module is calculated on the above basis, and the magnification ratio of the first amplifying circuit and/or the second amplifying circuit is adjusted in accordance with the rotation transformer ratio adjustment such that the first sine signal and the first cosine signal are in the sampling interval of the rotation transformer resolving chip.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor resolver intelligent identification system and a control method for the motor resolver intelligent identification system. Background technique [0002] In the development process of the motor controller, there are relatively many types of motors to choose from, and the resolver ratios matched by the motors are also different. If the resolver ratio of the motor controller is different from that of the motor, the output signal of the resolver will exceed the range of the signal collected by the resolver decoding chip in the motor controller, and the motor controller will report Malfunction, unable to perform normal use. [0003] Therefore, under the current technical conditions, the applicability of the motor controller is poor. Generally, the hardware solution of a motor controller can only match a motor with a resolver ratio, which is difficult to meet the use requirement...
