Research and Analysis of the Drive Motor Characteristics for Automotive Electronic Throttle

Modern automobile has entered into the times of electronic drive. The DC motor is one of the main components in applications of the automotive electrical drive, and but the pros and cons of the motor characteristics directly related to the response and control of the auto executing agencies. This article described a measurement method of DC motor characteristics by object of the system model and control strategy to drive vehicle electronic throttle body, and the relationship between the electrical characteristic curves of the DC motor discussed in-depth. Final experiment shown that the test method of characteristics proposed in the paper is effective and it is provided a theoretical and experimental reference for determination the motor characteristics.
