Research Background

Electric motor is broadly used in city railway transit now, especially traction  motor.At this condition,testing of traction motor controller is more and more important.In traditional traction motor test,there are some problems:expensive physical motor,high risk,construction cost,testing cost.Thus HIL(Hardware in the loop) testing is a better choice.By using HIL Real-Time testing can rapidly,efficiently,safety,economically accomplish traction motor controller test. Beside, by using this test form,quickly change motor type and start a new test become possible.

Challenge

◆ High precision motor simulation,indicate the simulation result accurately.

◆ Simulator Needs to support Multi type motor, meet the needs of different customers.

◆ High precision analog and digital in/outport,be able to process PWM and encoder signal in high speed.

◆ Low delay signal transportation, ensure that the motor controller test results are correct.

StarSim HIL Simulation Solution
