Precision high torque stepper motors, sizes from 35mm square to Super size 42 (4.34") 110mm square x 201mm long with HUGE 260 in-lb of torque. See the various integrated motor/controller drawings for motor details. Torque values below are rated torque, you may operate with more or less then rated. Rated torque is determined by the amount of amperage to develop rated torque and operate for 10 minutes before reaching 180 degree F. Note that torque developed by most competitor's drivers is less then the Excitron controller/drivers<

All motors are rated as high torque, approximately 30% higher than other same-size motors. When coupled with our Controllers, the motor torque is increased another 20% (50% gain). This is true for the normal published speed ranges up to 5,000 sps (maximum available from competitors for most motors). However, our motor torque is more than 100% higher above 5,000 sps, and continues up to 25,000 sps (full steps, depending on motor), where no other controller operates.

Size 42 and 57mm motors are available with high resolution of 400 steps/revolution, indicated with an "M" at the end. It is almost always advantageous to use "M" motors, and we price our motors aggressively.
