Festo stepper motors
Stepper motors enable precise positioning operations, and so they are used when high accuracy is required for demanding positioning tasks. They consist of a stationary stator and a rotor rotating inside it, which is driven by torque generated by differently aligned magnetic fields in the stator and rotor. The rotor always turns in such a way that the greatest possible magnetic flux is created. Stepper motors are primarily used in factory automation, but are also increasingly being used in machine and plant building.

Advantages of stepper motors
Stepper motors are characterised by a very high torque at a low rotational speed. This enables the application to be both started quickly and – thanks to the high holding torque – to be stopped easily too. The direction of rotation can also be changed quickly and at any time. Other important advantages of stepper motors are the high accuracy they offer during operation and the easy monitoring of the rotor position. In addition, stepper motors do not have brushes, which contributes significantly to the high mechanical resistance of the application.
