The four-pole brushless DC-Servomotors, which have uniquely flat coil technology with three flat, self-supporting copper windings and are used in the B-Flat series, form the basis for drive systems in applications where space is extremely limited. With their powerful rare-earth magnets, the motors deliver a continuous output of 1.5 W to 9 W and at the same time have only minimal inertia. In combination with the integrated gearheads in extremely flat design, the motors provide a very compact drive system with increased output torque. Due to the electronic commutation of the drives, the service life is many times longer compared to mechanically commutated motors.
