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.
Flat external rotor BLDC motor with a diameter of 90 mm and a rated power of 130 W for size S und 170 W for size L. The open design without rotor housing ensures optimal heat dissipation - especially at high speeds.
The DFA90 comes with two different windings for 24 and 48 V and is equipped with digital Hall sensors for easy control. This motor is also available with an integrated inductive 3-channel encoder with a resolution of 4,096 CPR (DFA90…-E).
