BLDC motors external rotor

With their compact design, the BLDC flat motors of the SOBL series are particularly suitable for applications with limited space (pumps, robotics, medical). The permanent magnets are located on the rotor bell, which rotates around the internal stator with the windings. The advantage of this design compared to internal rotor motors is the shorter design with the same power and the lower torque ripple due to the higher moment of inertia of the rotor.

Features

• Brushless DC motor with flat design
• Particularly light and compact design
• High torques thanks to external, multi-pole rotor
• Sensorless
