For precise control, this stepper is better
A 0.9° stepper motor provides more precision than 1.8° steppers. The motor uses a full or half-step drive instead of moreexpensive microstepping drives. It offers bidirectional operation, ± 5% noncumulative position accuracy, and 260 oz-in. of holding torque. The NEMA-23 motor measures 2.25-in. square and comes in multiple lengths. Motor housings are totally enclosed with permanently lubricated high-precision ball bearings. Options include a range of windings to match unipolar and bipolar drives, special lead wires, shafts, end caps, and connectors. Applications include medical instruments, robotics, office equipment, and linear and rotary-positioning systems.
