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.
