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.

Hold on tight! Has the strength to spin right out of your hands. 😀
Color: C-Stand Black, Size: Model C Rechargeable
What a pleasant surprise to experience this double whisk Electric Milk Frother!! The sheer power is incredible. Makes the most delicious blended Green Tea Match Latte, Dalgona Coffee and Mochas! The only "con" happened yesterday when I was frothing my Green Tea and the device just suddenly stopped! At the time, I wished that there was some sort of colored bulbs or other way of determining charge levels. A remarkably strong Milk Frother!

It froths, but is not dependent
Color: C-Black, Size: Model C Rechargeable
While this frother does “froth”, it has many more cons than pros. The ONLY pro is it froths. The cons—only good for a traditional coffee cup. It is not water proof, and the instructions say to keep the “unit “ dry. As you froth, the liquid naturally raises height. If you are trying to use a Togo coffee mug, or thermos type travel mug—it only works well if done it three or four levels to ensure keeping the motor above the liquid. The “rechargeable “ function DOES recharge, however- it may last 1use or a few. It’s VERY inconsistent. And does not seem to be related to how long you allow it to charge. Overall—not a good buy. I had mine maybe 3 months before it quit working. And at 2 months it started becoming spastic. Even after just being charged-it wouldn’t even froth 1cup. AVOID!!

Easy to Use and Works Great
Color: C-Black, Size: Model C Rechargeable, Color: C-Black, Size: Model C Rechargeable
This milk frother works amazingly well! It’s powerful, easy to use, and creates rich, creamy foam in just seconds. The rechargeable design is very convenient, and the battery lasts a long time between charges. It feels sturdy and well-made, and cleaning it is quick and simple. I use it every day for my coffee, lattes, and hot chocolate, and it has exceeded my expectations. If you’re looking for an affordable and effective milk frother, this is definitely a great choice. Highly recommended
