Gear trains are generally limited to 212 mN-m (30 in.- oz.) output or 639 mN-m (90 in.- oz.) of static torque.

All motors in speeds of 1 rpm and faster can be stalled indefinitely without electrical or mechanical damage.

Torque reduces in proportion to speed increases. Changes in torque rating do not change physical dimensions.

Voltages other than 24v, 110v and 220v are available.

Direction of rotation is determined facing shaft.

When Ordering
Please specify torque, type of output drive (including shaft length, diameter and standard or extended bearing), direction of rotation, type of mount, output speed, voltage and frequency.

Full Year Warranty
We will repair or replace without charge any Synchron motor which is used for an application approved by our Engineering Department which proves to be defective in materials and workmanship within one year from date of manufacture stamped on the motor.
