EOL Test Bench for DC PM Motors

4Q PI – Modeling none contact testing

Torque-speed characteristics measurements are essential in the design and manufacture of electric motors. Dynamometers have been widely used in motor characteristics measurements, and the coupling between the motor under test and dynamometer is a critical issue for high-power electric motors. DC motors have wide applications in industrial control systems because they are easy to control…

4Q CTS – Cogging Test System

Cogging toque is a natural characteristic of some permanent magnet motor design which is less desirable characteristic for many applications. It’s also known as ‘detent’ or ‘no current’ torque. Cogging torque is the torque needed to overcome the opposing torque created by the magnetic attractive force between magnets on the rotor and the iron teeth…
