Faulhaber Stepper Motor



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.

Two phase Stepper Motors with Disc Magnet

The rotor of a two-phase stepper motor with disc magnet consists of a thin, homogeneous disc.

The very low inertia enables high acceleration values. The disc is magnetised precisely with 10 pole pairs, resulting in a high angular accuracy. The stator is only located on one side of the motor. Four windings (two per phase) generate the axial magnetic field.

Special versions of this motor type are well suited for use in microstep applications as there is no cogging torque.


Stepper motors – two-phase permanent magnet technology

The FAULHABER stepper motors are multi-pole, two-phase motors with permanent magnets. Through the use of rare-earth magnets, an exceptionally high power to volume ratio is achieved. With its very low inertia, the rotor design predestines the motors for use in applications that require very high accelerations or rapid change of direction. Another important advantage is that they can start with a relative high speed right from the very first step, further shortening the time required for the acceleration ramp. With their short length and low weight, stepper motors can also be used in integrated systems.

Thanks to their robust design and simple operation, they are likewise ideally suited for the most difficult operating conditions. Due to the various operating possibilities of the full-, half- or microstep electronics, precise speed and motion control can be established in an open control loop.
