BLDC motors use electronic control rather than mechanical brushes. They are common in energy-efficient fans and can offer lower power use and quieter running, depending on the model.
Servo motors provide very precise control of position and speed. They are more common in automation and machinery than in ordinary home appliances.
| Motor type | Typical use | Key strength |
|---|---|---|
| Induction | Fans and pumps | Robust, economical |
| BLDC | Modern fans | Efficient, controllable |
| Servo | Automation | Precise movement |
They use electronic controllers, so faults may need more specialised diagnosis than a conventional motor.
It can point to a capacitor, supply or mechanical issue. Avoid repeated attempts if the motor is heating.
