Internal Rotor Drives for High Torque Applications

For applications demanding very high torque, drive specialist Maxon Precision Motors has launched its EC-i 40 DC brushless motor in a High Torque version. The iron-core internal rotor drive is available with a diameter of 40 mm and delivers up to 234 mNm of torque.

The Swiss drive specialist has released three powerful iron-core internal rotor drives. The drives have a diameter of 40 mm and are equipped with an innovative rotor. They feature high dynamics, a low cogging torque, and extremely high output torque. The strongest motor in this series offers a maximum nominal torque of 234 mNm and is 56 millimeters in length. It exceeds the performance of its precursor model by up to 70 percent.

The three compact brushless DC motors are suited for applications in robotics, prosthetics, and industrial automation. When needed, the EC-i 40 High Torque motors can be combined with maxon gearheads, servo controllers, or position controllers.
