Portable IDS - Inertial Dynamometer Systems

As a leading motor testing company, we're proud to introduce our latest innovation: Portable IDS, from our Inertial Dynamometer Systems. With the Portable IDS suitcase, we're revolutionizing motor testing by offering a portable solution that can be used anytime, anywhere. This system enables testing of motors on the go, allowing for unprecedented flexibility and convenience.
One of the key features of Portable IDS is its ability to upload all data and diagnostics of the motor directly to the cloud. This means that users can access the results of their tests from any location, facilitating further analysis and testing without being tied to a specific physical location. In essence, Portable IDS is not just a portable system for motor testing, but a comprehensive solution that integrates cloud-based data storage and analysis for seamless testing experiences.


The motor is accelerated from 0 to the no-load speed. The load used is the moment of inertia of the motor’s rotor + flywheel. From the acceleration period, the system gives the complete motor load performances, together with additional dynamic unique testing, such as ripple torque, 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.
