NEMA11-01
The NEMA11-01 is a compact bipolar stepper motor designed for precise motion and positioning tasks in confined spaces. Thanks to its small size, it is suitable for compact automation solutions as well as for modelmaking, maker, and industrial applications.
With 200 steps per revolution and a step angle of 1.8°, the motor enables finely graduated and controlled positioning. The NEMA 11 series is also designed for comparatively high speeds and, according to the data sheet, can reach speeds of up to 3,000 rpm.
The NEMA11-01 offers a holding torque of 0.055 Nm, combining compact dimensions with robust performance. This makes it suitable, for example, for positioning systems, metering pumps, locking mechanisms, or the precise adjustment of optical components.
With four open connection terminals, the motor can be flexibly integrated into custom control systems and designs. Measuring just 28 × 29 × 32 mm, the NEMA11-01 offers a versatile solution for applications that require precise motion while taking up as little space as possible.
