Measuring torque is essential for different kinds of tests and applications. Especially in electric-machine testing, it is important to understand the efficiency and dynamics. However, torque is not a static value: therefore, measuring torque with a high accuracy is crucial. A high-bandwidth torque measurement is also needed to understand what happens instantaneously. This could be:
What happens exactly during the measurement and how can cogging torque, torque ripple and other characteristics be measured and reduced? You will find the answers in the following videos and white paper.
From torque to electric power testing: in this video we will show you how to maximize the investment of your torque sensor by pairing it with the power analyzer of the eDrive series.
We are using a test rig to demonstrate an electric motor test with a torque transducer placed between the drive and the brake. With this test rig, we can control torque and speed to look at the different output states to imitate real world scenarios. To further visualize the benefits of the eDrive system, we have mapped the electrical and mechanical output of an e-motor. Watch the video to check out what it looks like in the software!
