About Sierramotion

Sierramotion, a division of Allient (formerly known as Allied Motion Technologies) helps customers design solutions to complex motion problems. The company then builds, tests, and supplies these unique products or transfers to Allient for volume production. Whether it is a simple coil, or a precision motion assembly working in vacuum, Sierramotion has the experience to create a solution that works the first time.

If you just need prototypes to validate the design or process, Sierramotion can make them in house, test and deliver. High volume serial production is transferred to Allient with its global manufacturing presence with more than 2300 employees and 21 locations, producing more than 3 million motors/year.

The team as Sierramotion has accumulated decades of experience and know-how designing and applying products in electro-mechanical systems with moving magnets or moving coils for rotary, linear, and arc shaped applications.
