4mm Small Coreless Motors Parameters
The NFP-D408 series is a 4mm small coreless motor line for compact and portable products. It includes NFP-D408-A, NFP-D408-B, and NFP-D408-C options.
First, these 4mm motors are very small and light. Also, each model weighs only 0.5g. Therefore, they are useful for products that need a tiny motor with high speed.
In addition, the 3.7V design works well with small battery-powered devices. As a result, these motors can fit many portable and low-power systems.
Main Product Features
- First, compact size: The 4mm body fits very small product spaces.
- In addition, low weight: Each motor weighs only 0.5g.
- Also, high speed: The no-load speed can reach up to 88,000rpm.
- Next, 3.7V power: The motor works with small battery systems.
- Finally, multiple options: Three models are available for different speed and current needs.
4mm Coreless Motor Performance Data
Next, the table below helps users compare voltage, speed, current, torque, output power, and efficiency. Therefore, it is easier to choose the right model for a small device.
| Model | NFP-D408-A | NFP-D408-B | NFP-D408-C |
|---|---|---|---|
| Voltage | 3.7V | 3.7V | 3.7V |
| Terminal resistance | 11.3Ω | 9Ω | 32.4Ω |
| No-load-speed | 84,000rpm | 88,000rpm | 54,000rpm |
| No-load-current | 50mA | 59mA | 16mA |
| Stall torque | 0.95g.cm | 1.15g.cm | 0.53g.cm |
| Stall current | 330mA | 410mA | 110mA |
| Max output power | 0.204W | 0.261W | 0.073W |
| Max efficiency | 35% | 36% | 37% |
| Torque constant | 3.4g.cm/A | 3.3g.cm/A | 5.4g.cm/A |
| Rotor inertia | <0.01g.cm² | <0.01g.cm² | <0.01g.cm² |
| Weight | 0.5g | 0.5g | 0.5g |
Also, the NFP-D408-A and NFP-D408-B are better for very high speed use. However, the NFP-D408-C has lower no-load current, so it can help reduce power use in some designs.

I absolutely love how quiet and smooth this motor is. The coreless design really reduces heat buildup, which is crucial for the long-term reliability of my wearable. Definitely a top-tier product.
Claudine Benson –
At just 0.5 grams, this little motor surprised me. Very fast response time and minimal current draw. Works great in battery-operated systems.
Cameron Naumann –
I bought some coreless dc motors to test my equipment, and the speed and current are very consistent. These motors better fit for my project than I imagined. Worked great !!Great value!!💛
Seth Yoder –
I ordered these motors for a physics project where students were constructing. The coreless motors were perfect engine in a mini wing dragon. Had to do some soldering but easy enough.
Donald Meyer –
These micro motors work great at rated volts, the wires are tiny but can hold up well to any abuse I’ve given them while installing the motors. And it fits my mini helicopter tail and has it running again.
Tregear, Ivan –
Nice mini coreless dc motor, its wires were stronger than other samples, high speed and suitable for me.👍
