The motors of the FAULHABER DM-Ring series are characterized by a special design: Similar to a hollow-shaft motor, the ring stepper motor offers a very large aperture of Ø 40 mm, which allows for laser or light signals, cables, gas or liquids to pass through the motor center, depending on the application. The direct drive consists of a magnetic disc with eight coils and runs without any backlash and with minimum friction. It supports very high loads due to big ball bearings and can operate with 200 steps per revolution.
Thanks to its very flat design and low weight, integration of the FAULHABER DM-Ring series into all kinds of applications is simple. The ring stepper motor is a great choice for highly demanding positioning tasks in areas like optics, aerospace or industry automation. It can be used for the precise rotation of lenses, while the light can be guided through the motor center. If the application requires electric cables routing in the motor center, they can be guided through the large aperture, while the motor drives antennas, turn tables or cameras.
