Outer Rotor BLDC Motor

 

High Efficiency 
Our external rotor motors are designed to deliver maximum efficiency and torque at rated speed ranges, allowing you to save energy while adapting performance to changing system demands. With a sleek design, they offer excellent performance in a compact, integrated package.

Low Noise Level
Noise can be a major nuisance when operating machinery; our external rotor motors produce low noise levels, making them suitable for a range of applications. As a brushless motor, friction and operating noises are negated, making it a great choice for production floors.

Reliable Performance
The brushless design of BLDC motors minimizes friction to prolong the life of internal components.  Wieldy motors have been further tested and certified to ensure they can stand up to the toughest conditions without sacrificing performance, for the life of your system.

Excellent Controllability
Wieldy Motor’s external rotor motors come with a range of control options, allowing you to easily adjust speed and direction. Smooth, stable rotation ensures revolutions remain precise.
Thanks to the higher inertia of the rotor, external rotor motors have a lower torque ripple than internal rotor motors.

Compact Size
The outer rotor design of out rotor brushless DC motors gives these products an exceptional power to volume ratio, while keeping them very light and compact.
Outer rotor motors are very short and offer a cost-effective solution particularly for large series.
