The invention discloses a standard motion device based on linear motor driving and a testing method thereof applied to a high voltage circuit breaker mechanical characteristic monitoring system performance verification platform. A linear motor driving platform does not need an additional device which converts rotary motion into linear motion, thus the structure of the system is greatly simplified, the weight and volume are greatly reduced, and the operation noise is low. Since the motion conversion additional device is not needed, various positioning errors brought by an intermediate link are eliminated, and the positioning precision is high. The super precise motion control can be realized, the requirement of performance index verification of a high voltage circuit breaker mechanical characteristic monitoring system can be completely satisfied, and the device and the method have good application and promotion prospects.
