Very flat external rotor motor with a diameter of 20 mm and a rated power of 5 W. The DF20 is available with two different windings and equipped with digital Hall sensors. The open design without rotor housing ensures optimal heat dissipation.

  • Rated speed of 5,200 rpm
  • Rated voltage of 12 V or 24 V
  • 8-pole design
  • Smooth and stable operation at low speeds
  • FPC cable

The DF20 is ideally suited for use in prosthetic devices, robotic grippers or medical pumps.

Please note:
To connect this motor with a Nanotec motor controller (we recommend the controller CL3-E), an additional board for adapting the FPC cable to wires is required.

Knowledge Base

Brushless direct current motors, abbreviated as BLDC motors, are – despite their name –  three-phase current synchronous machines: the rotor follows a magnetic rotational field and the movement is synchronous to the AC voltage applied to the windings. This motor type is frequently referred to as "brushless direct current motor" because, in many applications, it replaces direct current motors with brushes (brushed DC or commutator motors).…
