System and method for monitoring the processing performance indexes of motor

Abstract

The invention discloses a system and a method for monitoring the processing performance indexes of a motor. The system comprises a numerical control apparatus, a servo driver, a performance monitoring device and a tested servo motor. The servo driver is used to receive the instruction signals from the numerical control apparatus and controls the servo motor to transmit the actual position data fed back by an encoder; the numerical control apparatus is used to run the standard testing G codes and obtains the actual position data fed back by the servo motor encoder. According to the difference between the instruction position data generated from the running and moving of the tested servo motor and the actual position data, following error fluctuation data are generated and transmitted to the performance monitoring device. The performance monitoring device evaluates the processing performance of the tested servo motor according to the following error fluctuation data and makes statistics and saves the performance index of the tested servo motor. The monitoring system of the invention can be created easily; the measurement can be automatically performed; the operation is easy; the measurement time is shortened; and the measurement result is accurate.

Description

technical field [0001] The invention relates to the technical field of motor testing, in particular to a monitoring system and method for motor processing performance indicators. Background technique [0002] Usually, the user can judge the machining performance of the motor by the torque-speed characteristic, vibration and noise of the motor. The motor torque-speed characteristic performance test is to study the torque output of the motor at different speeds, which has an important impact on whether the rough machining of the part can be completed normally. The defect of the motor torque-speed characteristic will directly affect the contour of the part processing The motor vibration and noise performance test is the most basic test link of the motor factory inspection, which has a significant impact on the semi-finishing and finishing surface quality of the parts. The parts processed by the motor with vibration and noise will have uneven and complex lines . [0003] The q...
