25
+|---------------------|------------------------------------------------|-------------------------------------------------|
26
+| **Rotor Design** | No iron core (hollow cup winding) | Rotor has permanent magnets |
27
+| **Commutation** | **Brushed** (mechanical commutator with brushes) | **Electronic** (uses sensors or controller) |
28
+| **Inertia** | Very **low**, allowing fast response | Moderate, depending on design |
29
+| **Efficiency** | High (especially in low-power apps) | Very high (especially at medium/high power) |
30
+| **Noise** | Very **quiet** at low speed | Quiet, can produce high-frequency noise |
31
+| **Speed Response** | Extremely **fast** acceleration/deceleration | Fast, depends on controller and load |
32
+| **Lifespan** | Limited (due to brush wear) | Long (no brushes = less wear) |
33
+| **Maintenance** | May need brush replacement | Minimal maintenance |
34
+| **Control Complexity** | Simple (direct voltage control) | Requires motor controller (ESC) |
35
+| **Size / Weight** | Very compact and lightweight | Can be compact but larger for same power |
36
+| **Typical Voltage** | Low (e.g. 3V, 6V, 12V) | Can handle higher voltages (12V–60V+) |
37
+| **Cost** | Generally cheaper | More expensive due to controller and design |
38
+| **Best For** | Micro motors, medical devices, toys, robotics | Drones, RC vehicles, electric tools, e-bikes |

+A worm gear is a type of gear arrangement in which a screw (the worm) meshes with a gear (the worm wheel). The worm resembles a screw and is typically used to reduce speed and increase torque in mechanical systems.
5
+
6
+Worm gear systems are known for their ability to provide high reduction ratios in a compact space and for their self-locking capability, meaning the gear cannot easily drive the worm back.
