Get High Torque and Smooth Speed with Outer Rotor Brushless Motor

You must have seen that in a normal motor, the middle part is the part that spins. However, in an outer rotor brushless motor, it is built the other way around. The outside can of the motor is the part that spins around the center. This inside-out design is a good pick for jobs which need a lot of turning force. The design of this motor keeps the copper coils (the stator) stationary and locked in the center. Also, the magnets are placed on the outer can of the motor which is the part that spins.

At YueQing GuangHui Electric Co., Ltd., we are an outer rotor motor manufacturer who builds motors that you can trust. Our motors use good magnets with strong bearings to give you the power that lasts. As an outer rotor motor supplier, we build motors that give you the high torque and steady speed that your products need to work well. We know how much difference an outer rotor brushless motor can make for your items which is why we focus on creating motors which work in the best way possible.

What is Different About This Motor?

• It Creates More Torque: This inside-out design lets the motor have a wider shape and fit more magnets on the spinning can. This gives the motor more force when it turns and creates a much higher turning force at low speeds which is perfect for jobs that need a strong pull.
• It Spins Very Well: The heavy outer can is the part that spins and acts like a flywheel on the engine. This weight keeps the motor speed in control and helps it to run smoothly. This design also has no cogging or jerky moments at low speeds.
• It Cools Core Itself: The way that this motor is designed makes it very good at releasing its heat. Since the outer can spin at a high speed, it works just like a small fan that pulls cool air in and pushes hot air out. This spinning action helps to cool down the motor which also adds its lifespan.
• It Lasts Longer: This outer rotor brushless motor has no internal parts which can rub together to wear down the motor. The lack of friction means that there’s less damage and more running time without needing any service.

Feel the Difference!

The outer rotor brushless motor can give you a lot more tuning power along with a speed which doesn’t vary. Its inside-out design makes it a workhorse for machines like drones, powerful fans, and medical pumps.

Frequently Asked Questions

Are These Outer Rotor Motors the Same Ones Used in Drones?

Yes, this is the most common motor used for drones. This inside-out design creates the high turning force which is needed to spin a propeller and lift the drone into the air. The spinning can also help to keep the motor cool while it is flying.

Does this Motor Need a Special Electronic (ESC) to Work?

Yes, it does. This is a brushless motor, so it has no brushes. It must be used with an electronic speed controller (ESC) to run. The ESC is the part that sends power to the motor coils in the right order to make it spin.

Is an Outer Rotor Motor Harder to Mount in My Machine than a Normal Motor?

No, it is usually easier. The motor has a flat stationary base with mounting holes. This base (the stator) is the part that you bolt directly onto your machine frame. The outer can then spin freely around it.

What Does “Cogging Torque” Mean for this Motor?

“Cogging” is the lumpy or jerky feeling that you get in some motors when they turn slowly. Our outer rotor brushless motor models are made to have very low cogging. This makes their rotation very steady that is necessary for tools like scanners or fans.

What are the Main Jobs these Motors are Used For?

As an outer rotor motor supplier, we see these motors used in any job that needs high torque in a small size. The most common uses are for drones, high-power fans, and pumps. They are also used in some medical tools and robotics.
