Customer Need / Challenge
An electric vehicle manufacturer needed a torque measurement system for their electric vehicle motors. These motors run at significantly higher rotational speeds than their internal combustion engine (ICE) counterparts, and have much higher power densities due to the small size and light weight. The system would be used to test the torque and speed of their electric motors to achieve and ensure optimum instant peak torque performance.
Interface Solution
Interface’s AxialTQ™ Wireless Rotary Torque Transducer is a highly accurate system that provides the highest quality torque measurement. This product comes with the AxialTQ™ Output Module and the provided AxialTQ™ Assistant software, that can be installed on a test bench. Data results are calculated and collected in real-time.
Results
Interface’s AxialTQ Wireless Rotary Torque Measurement System accurately measured the torque and RPM of the electric vehicle motor and they were able to achieve their required instant peak torque.
