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.

A little thin but very cozy and comfortable, soft fabric
Size: Large, Color: Navy
Thin but super soft and extremely comfortable. I would have liked the fabric to be a tad bit thicker, thus the four stars instead of 5. I wore this with a denim blazer. It is a beautiful navy. I think I will order a size larger than normal and maybe then the thinner fabric won't be such an issue. Nice sleeve length, not too clingy.

Fit Comfort and no high slits which spoil long dresses
Size: X-Large, Color: Dark Green
Why such high slits? Why 2 splits? Always have to sew them up for more coverage and modesty,
especially when seated.
The manufacturer/seller
could appeal to more, and all ages of customers considering this dress purchase, if not for
these too long slits either side.
