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 resource
Format: Paperback
Great diagrams. Great resource/informational books. If any of your kids is curious about flight and physics. This is a great resource to have in a home, homeschool or classroom library!

Packed with ideas across most physics- a good purchase even for an adult.
Format: Paperback
Great information density! I though they did a good job of covering the basics to a higher resolution than I expected. I bought this for my 10 year old nephew, it's a bit out of his reach as far as information density- the pictures help a great deal but it is definitely a book that will require explanation for you ger children. I don't think it's ever too early to have exposure to this science.

Very good book
Format: Paperback
My son borrowed the book from local library, he kept reading and became very interested in physics. He asked me to buy one so he could read it anywhere anytime. We are very satisfied with this book.
