测功机（Dynamometer） Dynamometer, also called dynamometer, is mainly used to test the power of an engine. It can also be used as a loading device for gearboxes, reducers and gearboxes to test their transmission power. It can be divided into hydraulic dynamometer, eddy current dynamometer and electric dynamometer. An electric dynamometer uses a motor to measure the torque output from various power mechanical shafts and to determine the power of the device in conjunction with the speed of rotation. Since the power machinery may be of different rotational speed, the motor used as an electric dynamometer must be a motor with a smooth speed regulation. At present, more DC dynamometer, AC dynamometer and eddy current dynamometer are used. Introduction of MTS-II motor test system Form Dynamometer (magnetic hysteresis, magnetic particle, eddy current) KZQ-IIB dynamometer controller Input energy tester (alternating current, three-phase or DC) Computer Note: the DKZQ-II dynamometer dynamic controller must be allocated in the unstable area of asynchronous motor. function With manual, fixed-point and automatic testing methods, the load can be automatically loaded according to the settings, scanning the motor from no-load to blocking (or set the value) of the characteristic curve; Test result: the motor test data is displayed or printed in the form of report or curve, and can be saved and viewed. When displaying the curve, the curve coordinate parameter and the choice of abscissa and ordinate can be modified; Curve: the test curve of multiple motors can be compared in the same interface, curve coordinates, coordinate curve of the longitudinal and horizontal coordinate can be modified, the testing curve of color for each motor can be modified, the graph can be printed after comparison; The system can carry on the endurance test with load. When the motor is abnormal, it can alarm automatically and stop the test. The specific parameters can be set at any time. Characteristic The softwa
