Brushless DC motor for demanding operating room applicationsmaxon’s new brushless electric motor, the EC-4pole 30, delivers high torque (106 mNm) and is sterilisable – a DC motor suitable for hand-held surgical tools.

Featuring two pole pairs, this DC motor provides a nominal torque of 106mNm and an output of 150W. It has a hermetically sealed rotor, meaning that it can withstand over 1000 autoclave cycles.

The EC-4pole 30 is equipped with the special ironless maxon winding, which makes it highly efficient. Another key feature is that the torque and current behave linearly and the drive can be overloaded. It is available with an optional Hall sensor, as well as with a hollow shaft with a diameter of up to 4.1mm.

With the EC-4pole 30, engineers get a first-class drive for surgical hand tools that work flawlessly under the tough conditions of operating rooms. Go to for more information.
