EXTERNAL ROTOR MOTORS

 

External rotor BLDC motors are shorter than internal rotor motors and offer a cost-effective solution particularly for large series. In these motors the permanent magnets are mounted on the rotor housing which rotates around the internal stator with the windings. Thanks to the higher inertia of the rotor, external rotor motors have a lower torque ripple than internal rotor motors. 

 

Product Description

 

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
