How Did We Do It?

Being resourceful allows us to create a very compact motor. The motor features a unique laser welded end-cap (end bell) design that incorporates the bearings making it extremely slim and compact.

Multiple Mounting Options

Motors are offered in a variety of standard mounting options in NEMA 14 and NEMA 17 mountings. Available hole patterns include Thru hole OD 0.13, #4-40 UNC and M3 x 0.5.

Additionally, Lin Engineering can place the motor in almost any customer designed housing imaginable.

Multiple Shaft options are also available.

Other Available Options

Custom Winding

Customized Leads

Customized Leads

Custom connections can range from EMI or IP protection, to custom color coding.

Vacuum Rating

Vacuum Rating

Our special cleaning process combined with a vacuum bake-out is used to encourage outgassing of residual contaminants. Our process passes Class 10 clean room requirements.

signature series

This Motor is Part of Our Signature Series:

0.9 Degree step angle ensures smooth motion, while Signature Series further reduces resonance for higher accuracy. The Signature Series was developed to help reduce system resonance and provide overall smooth motion. Depending on Application, using motors with the Signature Series technology may result in up to 40% less resonance being produced.


Reduce Resonance

Depending on application, Signature Series Stepper Motor user can expect anywhere from 10-40% less resonance being produced.


Increase Accuracy

The design creates double the detent positions (un-energized cogging) in the standard stepper. When doubled, the amount of torque or drag that each detent position has is decreased by half, thus creating a smoother motor during operation.

Why Lin Engineering?

custom winding

We design and manufacture the smoothest, most accurate, and most innovative stepper motors available anywhere.

During the last 25 years, we’ve reinvented and perfected the stepper motor technology in order to solve problems that had no clear solutions. Today, with our large assortment of standard and custom stepper motors, we’re able to provide solutions to even the most unique pains in motion control.


Our R&D and manufacturing facility is located in the San Francisco Bay Area. We’ve tapped into the innovative spirit of the Silicon Valley by utilizing the best technology, and the smartest people, in order to provide the best motion control experience.
