Sample request

We aim to get you up and prototyping as quickly as possible. We stock off-the-shelf samples for each motor size, to support commercial development.

Our application engineers can advise on motor design and selection, mechanism design, and support the development of high performance motor drivers. They can also assist to validate the in-application performance and longevity suitability of a down-selected motor or mechanism design.

Contact our application engineering team to discuss your project, using the form, or email [email protected].
