10-axis motor no-load testing system

Abstract

The invention discloses a 10-axis motor no-load testing system, which comprises bus cables, knob switches, contactor coils, servo motor power cables, servo motor signal cables, drivers and servo motors, wherein the bus cables are connected with the knob switches and the contactor coils, each knob switch is connected with the corresponding contactor coil in series to form a closed loop, and the bus cables are connected with contactors. The 10-axis motor no-load testing system can be used for monitoring operation situations of ten motors simultaneously in the data monitoring aspect since all the servo motors to be tested are controlled by one PLC, thereby reducing complex programs of the system; and the 10-axis motor no-load testing system controls power supply of drivers by using the contactors, is provided with power supply indicating lamps, integrates the switches on an operation panel, and brings convenience for the operation and observation of the tester.

Description

technical field

[0001] The invention relates to the application technical field of a motor no-load test system, in particular to a ten-axis motor no-load test system. Background technique

[0002] In the process of motor factory inspection, no-load test is the most basic and effective inspection method. The no-load test can check whether the motor can run, whether there is abnormal noise when the motor is running, whether the motor temperature control sensor, brake and other accessories can work normally, and whether the no-load current of the motor is normal. In order to ensure the accuracy of the test, sufficient running time is required (about 2 hours). Conventional no-load testing of a motor requires an electrical test cabinet, which must have at least one PLC, a servo driver, and a display interface that is easy for workers to operate. In order to ensure the time of no-load test, it is necessary to increase the no-load test machine position. According to the conventio...
