Description
Stepper motors for demanding positioning tasks
For demanding positioning tasks that require a high level of accuracy, stepper motors are generally used. The name comes from the operating principle, as the stepper motors are driven by an electromagnetic field. This turns the rotor a small angle – a step – or a multiple thereof.
Robust assembly, high speed range, and exceptional performance in even the harshest environments make FAULHABER drive systems the perfect solution for demanding positioning applications. The stepper motors from FAULHABER are also characterised by a long service life and high reliability hanks to their electronic commutation (motor without brush).
They are available with a wide variety of modular servo components such as encoders, zero backlash gearheads or integrated lead screws.
Two-phase stepper motors
The rotor of a two-phase stepper motor consists of a plastic carrier in which the magnets are specially arranged so as to produce 10 to 12 pole pairs, depending on the motor version.
The large magnet volume guarantees a high torque. The quality of the magnet material enables use from very low temperatures and temperatures up to 180°C (special version). Two windings are used for the stators, one per phase. They are positioned on each side of the rotor. The inner and outer stator assemblies produce a radial magnetic field.
