Operating range (based on on ambient 25°C)
For each motor frame size (diameter / length), we present the operating range diagram that relates to the winding of the stock sampleable part. The part number of the stock sampleable part is shown in the diagram below, and the product page of the stock sampleable part, can be found in the ‘related products’ section towards the bottom of the page.

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.
