The motor is accelerated from stall to the no-load speed. The load used is the moment of inertia of the motor’s rotor with flywheel. From the acceleration period, the system gives the complete motor load performances, together with additional dynamic unique testing, such as torque ripple, cogging, friction, and back EMF. Since the entire measuring time is very short (acceleration time), the motor has no time to warm up. In such a way, the motor characteristics are given at constant pre-defined temperature.
The method is very accurate, (± 0.2%) test results are very well reproducible, regardless of the operator and independent of any brakes, especially of their additional mechanical losses. The method clearly shows the influence of the temperature on motor performance and efficiency.
The system includes a very user-friendly software, presenting the data in graphs and tables, and saving them for evaluation, comparison, quality assurance, etc.
