After taking over Dimatech, a Swiss manufacturer of high-performance stepper motors, FAULHABER now also offers this type of motor with higher performance and greater dynamics. The disc magnet motor differs from conventional motors mainly due to the extremely light rotor. It consists of a multi-pole magnet in the form of a disk mounted on the motor shaft. Its low weight minimizes rotor inertia and allows acceleration that cannot be achieved with any other technology in these dimensions.
This motor type is therefore particularly suitable for applications in which the speed or direction changes frequently and quickly. Due to its design, it is also predestined to carry out very small and precise stepping movements. The size of the magnetic poles and the shape of the magnetic circuit are also designed in such a way that they achieve the highest possible torque in relation to the rotor dimensions.
With their specific properties, these stepper motors are ideally suited, among other things, for automation applications in which small loads have to be moved very quickly. This is particularly common in the semiconductor and textile industries, as well as in medical technology and robotics. An additional advantage is the particularly low weight of the motors. This is especially important where the motor moves with the load.
