AC Synchronous Rotary

Saia® rotary stepper motors offer instant actuation or smooth variable positioning. Saia Motors have high MTBF and long predictable life in excess of 1 million cycles and are ideal for open or closed loop operation. Users benefit from ease of control through simple drive electronics and the position accuracy derived from step angles of 7.5° - 15°.
This range of rotary stepper motors can be custom engineered to meet the integration requirements of the customer’s application. The platform motors below are examples used in the applications noted. Saia Rotary stepper motors are an industry standard in airflow control applications.
