[0022] Example
[0023] like figure 1 As shown, the present invention includes a motor to be tested, a motor controller to be tested, an eddy current loader, a signal control unit, a signal conditioning circuit, a constant temperature controller, a console, a signal collector, a signal conversion unit, a logic protection amplifier circuit, a power Analyzer and display 12 parts.
[0024] Wherein, the motor controller to be tested is connected with the motor to be tested to control the speed, start and stop of the motor to be tested. The eddy current loader is connected to the motor to be tested through a coupling, which is used to load the motor to be tested. The signal control unit is respectively connected with the controller of the motor to be tested and the eddy current loader, and it can send control signals to the controller of the motor to be tested and the eddy current loader to control them.
[0025] The console and the display are man-machine exchange windows. The ...
