8.6mm x20mm Coreless DC Motor Data Sheets
The NFP-D8620 series is an 8.6mm x 20mm coreless DC motor line for compact and high-power products. It includes 3.4V and 7.4V options for different speed, current, and torque needs.
First, this motor gives strong output in a small body. Also, each model weighs only 5.3g. Therefore, it is useful for products that need high speed, light weight, and compact size.
In addition, the coreless design helps reduce cogging and mechanical resistance. As a result, the motor can run more smoothly and respond faster.
Main Product Features
- First, compact and powerful: The 8.6mm body gives strong output in a small space.
- In addition, smooth control: The coreless design helps reduce cogging and improve speed control.
- Also, low noise: The motor can run quietly in small devices.
- Next, wide application range: It can support DIY projects, portable devices, and small robots.
- Finally, durable build: Strong materials help support long service life.
8.6mm Coreless Motor Performance Data
Next, the table below helps users compare voltage, speed, current, torque, output power, efficiency, and weight. Therefore, it is easier to choose the right NFP-D8620 model for a compact product.
| Model | NFP-D8620-3665-1-3.4 | NFP-D8620-3665-2-3.4 | NFP-D8620-3665-3-7.4 |
|---|---|---|---|
| Voltage | 3.4V | 3.4V | 7.4V |
| Terminal resistance | 0.4Ω | 0.2Ω | 1Ω |
| No-load-speed | 44,000rpm | 51,500rpm | 46,000rpm |
| No-load-current | 135mA | 205mA | 140mA |
| Stall torque | 64.6g.cm | 89.36g.cm | 108.8g.cm |
| Stall current | 9,390mA | 15,180mA | 7,410mA |
| Max output power | 7.293W | 11.807W | 12.841W |
| Max efficiency | 73% | 73% | 72% |
| Torque constant | 7g.cm/A | 6g.cm/A | 15g.cm/A |
| Rotor inertia | <0.15g.cm² | <0.15g.cm² | <0.15g.cm² |
| Weight | 5.3g | 5.3g | 5.3g |
Also, the NFP-D8620-3665-2-3.4 gives the highest no-load speed. However, the NFP-D8620-3665-3-7.4 gives the highest stall torque and highest output power.
Therefore, users can choose the 3.4V high-speed model for faster output, or choose the 7.4V model for stronger torque and power.

Bought these 8mm motors to test a product I’m developing. All 4 motors fit perfectly and all worked fine after testing, pretty good little motors.💛
Joey Doll –
They are great replacements for my crashed micro drone motors. The leads are long enough to allow for at least one screwup in connection, these coreless motors have a lot of power and rev quickly.
Bill Collins –
Excellent mini coreless 3v dc motor, the wires are firmly connected to the body, and the metal shell is strong, runs smoothly. Just one of samples has a little noise…
