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.

Better than expected
Color: Stainless Steel, Color: Stainless Steel
I have to say, it has completely transformed my kitchen countertop organization. From the moment I unboxed it, the quality and thoughtfulness of the design were immediately apparent. The stainless steel construction feels extremely sturdy and durable, giving the holder a sleek, modern look that complements any kitchen décor. Unlike lighter, flimsier holders, this one feels solid and well-balanced, thanks to the weighted, non-slip base, which ensures it stays put even when tearing off a single sheet with one hand. The spring-loaded tension arm is an absolute game-changer. I can tear off a paper towel effortlessly with just one hand, which is perfect when I’m cooking, cleaning, or juggling multiple tasks. No more awkward pulling or having to stabilize the roll with my other hand—it makes the process smooth and frustration-free. One of my favorite features is the integrated spray bottle. Having a cleaning solution right on the holder is incredibly convenient. I can quickly grab the paper towel and spray my countertops or stovetop without having to search for a separate bottle, which makes daily cleaning routines much more efficient. The spray bottle is easy to refill, and the design keeps it snug and stable so it doesn’t tip over. Setup was a breeze it came fully assembled, so I could start using it immediately. The overall footprint is compact, so it doesn’t take up much counter space, but it still accommodates standard-sized paper towel rolls comfortably. Even larger rolls fit without any problem, and the holder handles the weight without wobbling. Overall, the Ultrean Paper Towel Holder with Spray Bottle combines functionality, durability, and style in one package. It’s perfect for busy kitchens, whether you’re cooking, cleaning, or entertaining guests. The convenience of one-handed tear, combined with the integrated spray bottle and sturdy base, makes it worth every penny. I’ve found myself reaching for it constantly, and it’s made my kitchen workflow so much smoother. Highly recommended for anyone looking to elevate their kitchen organization while adding a practical and stylish accessory.
