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 Summer Look & Very Comfortable Fit Perfect Vacation Shirt for Tall Guys
Color: Khaki, Size: Large
I am very pleased with the quality of this shirt. The material is incredibly soft and has a nice weight to it, making it feel durable yet breathable. It features a moisture-wicking property that makes it a clean-looking, essential summer shirt, especially for those warmer days here in Utah. I really like the tan color; it looks great and pairs easily with a pair of jeans, nice shorts, or even flip-flops and sandals.
At 6'5" and 260 lbs, finding a shirt that fits my height can be tricky, but the size fits me pretty good and the fit is actually better than some other extra-larges I have tried. Even with a little bit of a belly, it is very flattering and the soft material feels great against the skin. It is slightly shorter than some other XL shirts, but it still works well for my frame. We are heading out on a cruise this week, and this is definitely going to be my go-to shirt for checking out the ship and staying comfortable in the sun.
The washability is another high-quality factor—I always wash things before wearing them, and this one didn't shrink much at all. Everything from the color to the texture stayed perfect right out of the wash. Overall, I hope you enjoy this shirt as much as I did because it really is a well-made and good-looking product!
