Featuring two pole pairs, this dc motor provides a nominal torque of 106mNm and an output of 150W. It has an hermetically sealed rotor and can withstand in excess of 1,000 autoclave cycles.

The EC-4pole 30 is equipped with a special iron-less maxon winding, making it highly efficient, while the torque and current behave linearly, allowing the drive to be overloaded.

The motor is available with an optional Hall sensor and optional hollow shaft with a diameter of up to 4.1mm.
