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.

Exceptionally nice and light for older skin (with a couple of caveats)
Color: Medium, Size: 1.7 Fl Oz (Pack of 1), Color: Medium, Size: 1.7 Fl Oz (Pack of 1)
At 75, foundation can be a real challenge, too heavy and it settles into fine lines, looking caked on, and it will make you look way older than you are! I've always leaned toward a natural finish anyway, so when I discovered this tinted moisturizer at such a great price I was super happy! For the most part, it delivers. It has a noticeable luminous finish that reads as "shiny" on my skin, and it won't do much to conceal age spots (though honestly, I'm fully aware, that's not what a tinted moisturizer is designed for.) A dab of concealer handles my brown spots and for the shine, a light dusting of mineral powder does the trick. The SPF is of course, a big bonus. If you're an active outdoors person who wants effortless, natural-looking light coverage without the weight of a foundation, this is it.

Hydrating Tinted Mineral Sunscreen with Great Coverage
Color: Medium, Size: 1.7 Fl Oz (Pack of 1)
I really loved this tinted mineral sunscreen. Besides providing excellent sun protection, it gives the skin a natural and even tone that looks beautiful. The texture is lightweight, hydrating, and doesn’t feel heavy on the skin. It also helps cover small imperfections without looking cakey or artificial. Perfect for everyday use to keep the skin protected and moisturized.

Great product!
Color: Medium, Size: 1.7 Fl Oz (Pack of 1)
Really wish I had found this sooner. We spend a lot of time outdoors for baseball and this is perfect for the hot summers. I put this on with a little blush and it looks better than my foundation and protects my skin. Isn’t greasy like regular sunscreen. Skin isn’t dry after wearing either.

Doesn’t stink, not super thick and minimal white cast
Color: Medium, Size: 1.7 Fl Oz (Pack of 1)
The product is a lot thinner than other sunblocks. VERY creamy! The tint is sheer but it’s less sheer than I actually thought. Which is fine bc I’ll use it as more natural makeup in the summer time if I go anywhere. It’s not so much that you can tell either though! My sister who sees me every single day told me my skin looked “very youthful” today and didn’t know it was tinted spf. She had smelled my face when I wore another spf and had agreed the other one STUNK so badly but we didn’t smell anything on this one. I am fairly light but I got the medium based on reviews I searched for on tiktok. I figured the white cast would lighten it up somehow but there is NO WHITE CAST! But the color is still fine bc it isn’t chalky like la Roche posay tinted liquid spf. This is very natural! When I applied this product it looked SO SHINY. I almost regretted it…. But 20-30 min later (I applied it then immediately drove 15 min to my sisters house) the product had set and it has a much more natural and dewy but not crazy oily finish. I love it so far. I do consider myself to have very sensitive dry/combo skin and am in the process of repairing a damaged skin barrier. This didn’t itch or burn or anything. I did notice it started pulling after rubbing it in so much but I did kinda rush my morning routine this morning. I’ll update if it wasn’t my bad.
Update: it’s been 5 hrs since I applied it. It’s definitely not going to be doubling as a moisturizer. I don’t feel like it’s dehydrated but it’s not moisturizing like other sun screen has been. But maybe just expected it to since it’s cerave but it’s not marketed as such. But that’s ok with me bc I’m more worried about the SPF part of the product.
Shade: at first I didn’t notice bc I was just indoors…. But it has enough tint for someone to notice the change in skin tone between my face and body so now I’m going to need to order the light one

Outstanding sunscreen.
Color: Medium, Size: 1.7 Fl Oz (Pack of 1)
I just ordered my second bottle of this sunscreen. I live in Florida so sunscreen is a big necessity.
Love it. The little tint is perfect and it feels great. It is not overly greasy. I do apply a little powder
and a little blush then I’m on my way out the door. I highly recommend this product.
