Santa Clara, CA - Source Engineering, Inc. (SEI) has introduced a low cost, series of custom 0.9 degree NEMA 14 steppers for OEMs. The 0.9 degree step angle assures smooth operation even at low speed. Specifiers can custom design a SEI 0.9 degree hybrid stepper to meet the performance requirements of a new project or to increase performance and reduce cost of an existing application. By specifying the motor length, windings, and mountings these steppers can be configured to provide the torque and performance required, and be easily integrated into the application. Applications include: Printers and plotters, X-Y tables, medical instruments, scanners, security camera positioning, office equipment, index tables, and robotics.

These high performance 0.9degree steppers are available with four or six leads to meet torque and performance requirements. For example: A typical 4.5 V, 0.9degree NEMA 14 stepper just .87 in. (22 mm) deep has a holding torque of 5 oz/in. (six leads) and 8 oz/in (four leads), and is rated at 0.45 A/phase. Additionally, the type, color and length of the lead wires as well as connectors can be specified. Other options include: Choice of bearings and custom shafts (single or double, length, flats, pinions, keyways).
