LD Series

Synchronous servo motors for highly dynamic cyclical positioning of small masses – highly dynamic


With an integrated permanent magnet brake, the brake attachment is backlash-free and causes no brake abrasion. It increases the service life of the LD motor. Encapsulated stator windings dissipate heat well, as well as being reliably electrically insulated and protected.


Synchronous servo motors of the LD series are undemanding in terms of ambient conditions, space and installation position. The shaft has a fixed bearing on the B-side.

Highly dynamic

Thanks to their low moment of inertia, they accelerate quickly, thereby increasing the productivity of the machine.
