The Life Test allows the Customer to simulate the behaviour of the motor with applied different load or different operating conditions of voltage, also for long periods of time. The test is divided into cycles, which can be repeated for a settable number of time. The cycle is composed by a certain sequence of working conditions called phases. In each phase the Customer can set the load, the duration in time and the voltage supply. The System ATC320/W will keep on acquiring continuously the electrical values, the torque, the speed, the temperature and the resistance; with all these data the System ATC320/W automatically builds a graphic with observed trends of these values versus time. In addition of the time duration, it’s possible also to configure the stop of the tests when the current or the temperature exceed a selected threshold.
The picture on the right shows the interface (in this case, graphic and table) of the test results, which are the Torque, the Speed, the Mechanical Power, the Current, the Voltage, the Current Density, the Electric Power, the CosFI, the motor Efficiency, the Temperature and the winding Resistance.
