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.

Happy customer
Color: Black, Size: 32 LB, Color: Black, Size: 32 LB
I recently purchased a set of black dumbbell weights, and I couldn't be happier with my decision!
These dumbbells are solid and built to last. The weight material feels durable, and I can tell they're gonna last. These weights are perfect for all my exercises. They come in a range of sizes, allowing me to easily adjust the weight for different muscle groups. I love the sleek black finish! It not only looks stylish in my home gym but also adds a touch of professionalism to my space. The price point is excellent considering the quality and durability of these dumbbells. I've seen similar products at a much higher price, but these offer the same benefits without breaking the bank. Their design makes them easy to grip, and the smooth texture ensures I can maintain my hold even during the sweatiest workouts. Plus, they're compact and easy to store, making them perfect for home use.
Overall, these dumbbell weights check all the boxes. I highly recommend them to anyone looking to enhance their fitness journey!

Great Set
Color: Multicolor, Size: 146 LB
This is a great set of dumbbells. I was looking for the weights in this set and I wanted a nice rack to keep them off the floor. So far they feel solid and accurate and are working as expected. The reason for 4 stars and not 5 - The (2) 20 pound dumbbells shipped separate, which was fine...but everything else was in 1 box! That's 106 pounds plus the rack and packaging. The delivery guy struggled and almost dropped it, and then I had to move it from my front door step. How much more could it cost them to ship it in 3 boxes or redistribute it into 2 boxes under 100 pounds? So lucky the box didn't drop and the contents get lost or wrecked.
Otherwise it is a great set!

Great weights !!!
Color: Blues, Size: 76 LB
VERY HEAVY box. These are great weights that are not rough on your hands. Putting together the stand was simple and makes the storage simplified.
