Maxon EC-4pole 30 Brushless DC Motor Provides Nominal Torque of 106 mNm

Maxon motor has developed a brushless DC motor for hand-held surgical tools: the EC-4pole 30. 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 ironless maxon winding, which makes it more efficient. Another 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.
