Our NEMA 8 series are very small high torque stepper motors that can reach speeds of up to 3000 rpm.
These motors are often used in the model making and maker scene as well as in the industrial enviroment (Positioning of optics, dosing pumps, interlocks, etc.).

The special feature of this motor is the hollow shaft, which makes it possible to transport e.g. a compressed air or liquid line, power supply or even light through the shaft.
