Brushless Synchronous Servo Motor
Ideally suited for use in industrial environments

Synchroner Servomotor

Compared to a brushed servo motor, a brushless synchronous servo motor has no carbon brushes for commutation. The power supply to the phases is controlled by a servo drive. Without high-maintenance carbon brushes, you get a very durable drive.

Other advantages compared to brushed BDC servo motors include significantly lower electrical interference, the possibility of operation at higher voltages, a more compact design and lower energy consumption.

Synchronous servo motors differ from conventional brushless DC motors in that they are designed for precise positioning and/or high speed. This means you can use them for positioning highly dynamic axes.
