Abstract

Disclosed in the invention is a constant-current-source-based high-efficiency eddy current power measuring system comprising a signal control unit, a to-be-measured motor controller, an eddy current loader, a control console, a to-be-measured motor, a signal acquiring device, a signal conversion unit, a power analyzer, a thermostatic controller, a display, a constant-current control unit, and a power supply. The o-be-measured motor controller, the eddy current loader, and the control console are connected with the signal control unit; the to-be-measured motor is connected with the to-be-measured motor controller; the signal acquiring device is connected with the to-be-measured motor; the signal conversion unit is connected with the signal acquiring device; the power analyzer is connected with the signal conversion unit; the thermostatic controller is connected with the eddy current loader; the display is connected with the control console; the constant-current control unit is connected with the to-be-measured motor controller; and the power supply is connected with the constant-current control unit. Besides, the power analyzer is also connected with the control console; and the to-be-measured motor is connected with the eddy current loader. The system has the constant working current and thus is not influenced by the current fluctuation, thereby improving the stability.

Description

technical field [0001] The invention relates to a detection system, in particular to a high-efficiency eddy current dynamometer system based on a constant current source. Background technique [0002] At present, the main means of testing the electric performance of electric vehicles is to use the equipment for testing traditional internal combustion engines to complete loading tests, use testing equipment such as voltmeters and ammeters to perform data detection of electrical parameters, and then process and analyze data after the detection is completed. However, there is a big difference between the test of the electric system and the test of the traditional engine. The traditional internal combustion engine mainly detects the characteristics of the motor's speed and torque, and its corresponding parameters such as power factor, line voltage, line current, and active power cannot be directly calculated. Moreover, the real-time performance of detection equipment such as vol...
