Torque sensor facilitates prototyping & development stages of electric motor

04 February 2019

Ashwoods Electric Motors is a developer and manufacturer of advanced and innovative electric motors, produced on a large scale. In 2017, Ashwoods increased its workforce twofold and secured new premises with a new testing facility, equipped with multiple dynamometers where the motors are tested according to heavy-duty pre-set cycles, which are used for validation and performance testing.

The facility also contains a vibration test rig, which is used for prototyping more efficient electric motors, which can be up to a third of the size and weight than traditional motor technologies.

To take electric motor designs from concept through simulation and prototype to production swiftly, the Ashwoods team is constantly benchmarking its products to match international standards on automated dynamometers, which are designed in-house. The team required a relatively small dynamometer torque sensor in a neat package, that could fit into its existing dynamometers, to test the longevity and failure modes of the electric motors.

A torque sensor is a crucial part of the dynamometer, as it allows accurate measurement of motor performance, providing data to easily calculate input/output power and efficiency. Testing electric motors with a wide range of power outputs ensures that they operate at optimal efficiency.
