brushless
| Type | Brushed / Brushless | Key Traits | Application |
|---|---|---|---|
| Coreless DC motors | Brushed | Very lightweight, fast acceleration | Drones, medical tools, high-end RC |
| DC gear motors | Brushed | Built-in gearbox for torque | Robotics, automation, lifting mechanisms |
| Brushless DC motors (BLDC) | Brushless | Efficient, no brushes, often sensorless | E-bikes, drones, industrial fans |
| Stepper motors | Brushless | Precise, incremental rotation (not continuous) | 3D printers, CNC, camera sliders |
| Servo motors | Brushed / Brushless | DC motor + feedback + control board | RC, robotics, automation |
| Industrial DC motors | Brushed | High voltage/power, long-duty cycles | Conveyor belts, mills, elevators |
🧱 Common Types
| Motor Type | Gearbox Type | Used For |
|---|---|---|
| Brushed DC motor | Planetary / Spur | Robotics, automation, wheels |

coreless Motor vs. Brushless Motor
⚙️ Coreless Motor vs. Brushless Motor
| Feature | Coreless Motor (Coreless DC Motor) | Brushless Motor (BLDC) |
|---|---|---|
| Rotor Design | No iron core (hollow cup winding) | Rotor has permanent magnets |
| Commutation | Brushed (mechanical commutator with brushes) | Electronic (uses sensors or controller) |
| Inertia | Very low, allowing fast response | Moderate, depending on design |
| Efficiency | High (especially in low-power apps) | Very high (especially at medium/high power) |
| Noise | Very quiet at low speed | Quiet, can produce high-frequency noise |
| Speed Response | Extremely fast acceleration/deceleration | Fast, depends on controller and load |
| Lifespan | Limited (due to brush wear) | Long (no brushes = less wear) |
| Maintenance | May need brush replacement | Minimal maintenance |
| Control Complexity | Simple (direct voltage control) | Requires motor controller (ESC) |
| Size / Weight | Very compact and lightweight | Can be compact but larger for same power |
| Typical Voltage | Low (e.g. 3V, 6V, 12V) | Can handle higher voltages (12V–60V+) |
| Cost | Generally cheaper | More expensive due to controller and design |
| Best For | Micro motors, medical devices, toys, robotics | Drones, RC vehicles, electric tools, e-bikes |
