Mini foldable washing machines have become popular on platforms such as TikTok and Amazon due to their compact size, portability and suitability for travel, dormitories and baby clothes cleaning. The core component inside the machine is the motor, which determines torque, stability, noise level and service life.
Most foldable washing machines on the market use 3530 or 3429 series high-torque micro brushed DC motors with gear reducers. These motors offer:
High torque to rotate wet clothes and water
Noise level below 50 dB, quieter than normal conversation
Compact size approx. 35×30 mm, suitable for foldable structure
Carbon brush design, simple and low-cost maintenance
| Parameter | Description |
|---|---|
| Voltage | Affects motor speed and power output, commonly 6V or 12V DC |
| Speed (RPM) | Higher speed results in lower torque and needs to match the load |
| Gear Ratio | Higher ratio provides higher torque and lower output speed |
| Torque | Determines load capacity and washing effectiveness |
| Feature | Brushed DC Motor | Brushless DC Motor |
|---|---|---|
| Cost | Lower cost | 2 to 3 times higher cost |
| Speed Control | Voltage control only | Requires controller and program |
| Start-up Torque | Fast response and strong torque | Smooth start, more complex |
| Noise | Moderate, can be optimized | Lower noise |
| Lifespan | Medium, depends on brush wear | Longer lifespan |
Therefore, brushed DC gear motors remain the mainstream solution for foldable washing machines due to their cost efficiency and simple structure.
