Abstract

The invention discloses an electromagnetic coupler comprehensive performance test bench and a test method thereof. The test bench comprises a rotary induction motor, a power meter, an intelligent speed regulation electromagnetic coupler, a temperature sensor, a water pump, a throttle valve, a flow meter and a water bucket. The intelligent speed regulation electromagnetic coupler comprises an excitation rotor and a squirrel cage rotor, wherein a fixed shaft is fixedly disposed on the excitation rotor, and a telescopic shaft is fixedly disposed on the squirrel cage rotor. The power output shaftof the rotary induction motor is fixedly connected with the fixed shaft, and the telescopic shaft is fixedly connected with a water pump rotating shaft in the water pump. The fixed shaft is provided with a first rotary encoder and a first torque sensor, and the telescopic shaft is provided with a second rotary encoder and a second torque sensor. According to the invention, a working condition canbe comprehensively tested. Various performance indexes, temperature, efficiency, power factor and energy-saving effect can be acquired; comparisons in different aspects can be carried out. The comparison between couplers and throttle valves can be realized.
