The Motor Drive AR 403/-S is equipped with a AC motor (750 Watts).

The sturdy ball bearing worm gear drive is completely maintenance free and provides an output torque of max. 30 Nm. The unit features electronic speed control variable between 0 and 400 rpm.

The Speed is regulated by a digital dial. By a permanent nominal/actual adjustment the pre-selected speed is kept, even under varying load.

The AR 403-S is similar to the AR 403 but offers a different connection to the attachment. This connection is designed for better transfer of the torque. It can be used with some of the ERWEKA attachments.
