With OSM's huge assortment of High-Torque Stepper Motors, a customer can select the most cost-effective solution, never sacrificing quality or system performance. The stepper motors product line ranges from the smallest Nema 8 stepper motors with 2.5 oz. inches of torque, to the largest Nema 42 stepper motors with up to 5,700 oz. inches of torque! A high-Torque Stepper Motors has a 1.8-degree step angle as standard, yet other step angles are available. Four, six and eight-lead configurations are standard for OSM's stepper motor product line, and are model dependent. Other options available are conduit boxes, special stepper motors windings, shaft modifications, as well as cable, connector, encoder, brake, and gearbox adders.

Stepper motors.

1.Inherently a digital device, number of pulses determine distance, frequency sets the speed. 2.Drift free. 3.The step angle error is very small and non-cumulative. 4.Rapid response to starting, stopping, and reversing. 5.Brushless design for reliability, simplicity. 6.High torque per package size. 7.Stable at zero speed. 8.Holding torque at standstill. 9.Can be stalled repeatedly and indefinitely without damage. 10.No extra feedback components required (encoders can be added for additional advantages). 11.Bidirectional operation. Standard cotton box.
