The Electric Control System of Mechanical Transmission Test-bed With Mechanical Closed Cycle And Electric Colsed Cycle

This paper presented the principle and combinations of the mechanical transimssion test-bed with mechanical closed cycle and electric closed cycle. This system is composed of variable velocity driver, motor, generator, inverter and computer. It can be used both in mechanical closed cycle test-bed and electric ciooed cycle test-bed. The test-bed can keep a realting monitoring over the system and control the rotational speed and torque by computer. It can also simulate the real work condition of the test and to do the test. In this paper,the diminishable magnetization velocity modulation,invertiable control,the test data and curve,and the inverting efficiency as well as control scheme and presented.
