Maxon Motor has developed a robust brushless DC motor for hand-held surgical tools: the EC-4pole 30. This brushless electric motor delivers high torque (106 mNm) and is sterilizable, making it a perfect drive for hand-held surgical tools. Featuring two pole pairs, this DC motor provides a nominal torque of 106 mNm and an output of 150 W. It has a hermetically sealed rotor, meaning that it can withstand over 1000 autoclave cycles.
The EC-4pole 30 is equipped with the special iron-less 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 4.1 millimeters. 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.
