Features

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.

High-Precision Magnetic Encoder

Equipped with a high-precision magnetic encoder, the motor offers robust power and superior performance compared to a stepper motor. With an AB-phase incremental hall encoder, it delivers high precision, anti-interference, and other advanced features.

Durable Metal Gear

The motor incorporates a full metal gear and metal output shaft, reducing power consumption and extending the motor's service life.

How to Select Right Motor
The line chart below illustrates the relationship between the gear ratio, rotation speed, and torque. This data pertains to scenarios where the inner motor of the geared motor remains unchanged.
What is a Hall Encoder Speed-Ranging Motor
The Hall speed-ranging coded disc is a ranging module that incorporates a hall encoder and a strong-magnetic coded disc. It generates a pulse signal through the AB phase, enabling the detection of the motor's rotation direction and speed.

Decent Shoes with Misleading Description (Not Leather)
Size: 12 Wide, Color: Black, Size: 12 Wide, Color: Black
I only look for leather when I’m purchasing dress shoes. Under the description “details” on this item it lists the shoe as leather upper and inner lining. A photo shows “genuine Napa leather lining”. If you keep reading (which I have now that I’ve received the shoes) it shows “faux leather” in the small print and that is not “leather”. I run a small leather business and this irks me because it’s clearly false advertising. The details also show the product is made in Brazil but when they arrived today, the shoe tag shows “Made in China” and “Man Made upper and lower”. I don’t hate the shoes. They look nice. What I know is they won’t hold up over time like leather, which is why the description should be accurate and not misleading.

All-Day Comfort, Perfect Semi-Casual Office Shoes
Color: British Tan/Java, Size: 10
Amazing, comfortable shoes for the office. These are by far the best I’ve tried for a semi-casual look. They’re incredibly lightweight and feel like you’re not wearing anything at all. Perfect for all-day wear.
