节能型电动机机电性能测试装置的研制

Development of the unit for tesing machancialand electrical function of motor

通过对修复后的大功率电动机采用反馈法作负载试验，使被试电动机拖动陪试电动机超过同步转速作发电机运转，并向电网馈电。采用单片机系统测试电动机的各项性能指标。

This unit is applied to the test of load for the maintained heavy power motor withfeedback. When the speed with which the tested motor drives company motor transcendssynchronous rotating speed, the electrical power is feeded to ecectrical networks. The parameters of the motor are measured by single--chip computer system, which has higher precision and economiza non on power, therefore this unit has the better economic benefits anddevelopment prospect.
