With Anaheim Automation'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 motor product line ranges from the smallest NEMA 08Y series with up to 4.9 oz. inches of torque, to the largest NEMA 42K series with up to 5,700 oz. inches of torque. The stepper motor line includes Specialty-Type Stepper Motor, such as IP65-Rated Stepper Motors and Integrated Stepper Motor-Driver-Controller packages, wherein the driver/controller circuitry is built into the stepper motor assembly (See Stepper Motors with Integrated Drivers/Controllers). Most high-Torque Stepper Motors have a 1.8-degree step angle as standard, yet other step angles are available. Four, six and eight-lead configurations are standard for Anaheim Automation's stepper motor product line, and are model dependent. Other options available are conduit boxes, special stepper motor windings, shaft modifications, as well as cable, connector, encoder, brake, and gearbox adders.
