Problems solved by technology

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 Fault, can not be used normally
[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 requirements of the motor controller platform.

Abstract

Disclosed are a motor resolver intelligent identification system, and a control method thereof. The system comprises: a motor resolver module (10), a resolver decoding chip (20), a first amplification circuit (30), a second amplification circuit (40), and a controller module (50). The motor resolver module (10) outputs a sine / cosine signal to the second amplification circuit (40). The second amplification circuit (40) performs signal amplification on the sine / cosine signal, so as to output a first sine signal and a first cosine signal. The resolver decoding chip (20) acquires the first sine signal and the first cosine signal, and outputs a group of excitation signals. The first amplification circuit (30) performs signal amplification on the group of excitation signals, and sends the amplified excitation signals to the motor resolver module (10). The controller module (50) acquires the amplified excitation signals and the sine / cosine signal, calculates a resolver ratio of the motor resolver module (10) according to the excitation signals and the sine / cosine signal, and adjusts an amplification factor of the first amplification circuit (30) and / or the second amplification circuit (40) according to the resolver ratio, such that the first sine signal and the first cosine signal fall within a sampling interval of the resolver decoding chip (20).

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...
