N4L UK, in cooperation with our North American colleagues attended APEC 2022 in Houston Texas.

We showcased the real time PWM motor drive measurement capabilities of the PPA3500 precision power analyzer.

For the exhibition, we built a fully enclosed PWM Test Bench with back to back motor drives. The system included a Torque and Speed sensor, shaft coupling to the load motor, resistive load for the regenerative load motor. The entire system was then cased in a aluminum extrusion based chassis with transparent polycarbonate panels.
