Product Introduction
The Hall speed measurement code disc is a speed measurement module that utilizes Hall sensor encoders. Equipped with a strong magnetic disc, it generates AB phase output pulse signals, enabling the detection of motor rotation direction and speed. It is suitable for various intelligent vehicles with high-speed requirements, such as Mecanum wheel vehicles, balance cars, navigation positioning vehicles, etc.
Wrapped Rear Tail Shell
The motor features an wrapped rear tail shell designed to provide robust protection for the PCB circuit and magnetic ring, shielding them from external influences. This design enhances safety and extends the overall service life of the motor.
Permanent Magnet Brushed Motor
The permanent magnet DC motor offers rapid response, startup torque, and smooth shifting. These features eliminate vibrations during speed changes from 0 to the maximum, enabling it to handle larger loads during startup.
Suitable for Various Scenarios
With a 1:20 ratio, the low-speed configuration matches a 1kg.cm torque, allowing the motor to adapt to a variety of chassis materials and diverse scenarios.
Durable Metal Gear
The motor incorporates a full metal gear and metal output shaft, reducing power consumption and extending the motor's service life.

Great option for a great price
Size: 7.5, Color: Black
I love these sandals. They are well made, true to size and soft suede. They are lightweight and feel just like my UGG goldenstar sandals. (These are not as adjustable, so if you have narrow or wide feet, these may not be for you) These a great value for the money, especially for medium width feet. The strap across the toe is not adjustable, but fit my feet just fine. The ankle strap was a good length for me. And the Velcro is strong. These sandals are a great value for the money. I will probably start looking into kookaburra before I rush to buy the more expensive ones now.

Quality, good looking shoes!
Size: 8.5, Color: Green
Absolutely perfect fit, design, and color. I'm so pleased with these sandals and as always with this brand, I am not in anyway disappointed. These shoes are so comfortable right out of the box. They clean up very nicely, and last forever. I am so glad I got these before they were sold out.

UGG Comfort Without the Premium Price
Size: 9, Color: Beige, Size: 9, Color: Beige
These sandals are super cute and incredibly comfortable. They have that classic UGG look and feel, but at a much more approachable price point.
The footbed is cushioned and supportive, making them easy to wear for extended periods. The straps feel secure without rubbing, and the overall construction feels solid and well made. They’re lightweight but still have a sturdy sole with good traction.
They pair effortlessly with casual outfits and have that relaxed, elevated vibe UGG is known for—just without the higher price tag. A great value for both style and comfort.

Ugg comfy shoes
Size: 7, Color: Black
So comfortable and cute as well. I wore these the first time and had to have everyone touch them to see how the sole would squish. Fit well, and are lightweight as well.
