Problems solved by technology

[0002] At present, there are many kinds of motor measurement equipment on the market, but they are basically adjusted manually, and the accuracy of the adjustment effect is not ideal. The measured motor characteristics are far from the ideal value. To measure the value of one point, the motor needs to be adjusted repeatedly. It is difficult to achieve an accurate value, and it is necessary to manually record the measured data and draw the curve, which takes a lot of time
In addition, the existing motor measurement equipment cannot realize the motor speed closed-loop operation and current closed-loop operation
Existing equipment that can realize automatic measurement of motors generally uses PC (computer) boards to collect signals and use host computer software to process data. The manufacturing cost of such equipment is relatively high, and closed-loop testing cannot be achieved.

Abstract

The invention discloses a device and a method for automatically measuring multiple motor characteristics. Through an operation platform composed of a to-be-tested motor, a rotary encoder, a clutch and a static torque sensor, carrying out data collection through an analog quantity signal input module of a PLC and communication functions of an intelligent 485 instrument, various parameters of DC motors and AC motors can be visually displayed on a touch screen, input voltage and frequency of the motors can be automatically adjusted through data acquisition of the PLC and the 485 communication functions, and loading for load ends of the motors can be further automatically carried out, full automation motor loading functions from a zero load to a setting load can be realized through PID operation of the PLC, then corresponding motor operation parameters of each loading point can be automatically recorded on the touch screen, and characteristic curves of the motors can be further drafted. According to the device and the method, rotating speed closed-loop and current closed-loop PID adjusting functions for the motors can be realized, so the motor operation characteristics under the condition of closed-loop adjustment can be measured.

Description

technical field [0001] The invention relates to the field of motor measurement, in particular to a device for automatically measuring characteristics of various motors and a method for measuring the same. Background technique [0002] At present, there are many kinds of motor measuring equipment on the market, but they are basically adjusted manually, and the accuracy of the adjustment effect is not ideal. The measured motor characteristics are far from the ideal value. To measure the value of one point, the motor needs to be adjusted repeatedly. It is difficult to achieve an accurate value, and it is necessary to manually record the measured data and draw the curve, which takes a lot of time. In addition, the existing motor measuring equipment cannot realize the closed-loop operation of the rotational speed and the closed-loop current of the motor. Existing equipment that can realize automatic measurement of motors generally uses PC (computer) boards to collect signals and...
