23
+### 1️⃣ Three-phase windings (U / V / W phases)
24
+
25
+The usual colors are: yellow, green, blue
26
+
27
+These three phases are commutated in sequence to make the motor spin.
28

36

37
+The motor is an outer rotor structure (the shell rotates).
38

40

41
+## ⚡ Why are there only three thick wires? Isn't that too few?

43
+It's not too few, because:

45
+These three wires are the power wires.
46
+
47
+Some motors also have Hall sensors (5 thin wires).
48

49
+Electric scooters usually have two types:
50
+
51
+| Type | Number of Wires | Features |
52
+|---------------------|------------------------|------------------------------------------|
53
+| Sensorless BLDC | Only 3 thick wires | Starts by induction, more vibration at low speed |
54
+| With Hall PMSM/BLDC | 3 thick + 5 thin wires | Smooth start, suitable for FOC control |
55
+
56
+## 🛴 Why do electric scooters use three-phase brushless motors?
57
+
58
+Because the advantages are obvious:
59
+
60
+- High torque
61
+- High efficiency
62
+- Silent operation
63
+- Maintenance-free (brushless, no wear)
64
+- Simple structure (directly integrated in the wheel)

66
+Almost all modern scooters (Xiaomi, Ninebot, Kaabo, etc.) use this type.

+### FOC (Field Oriented Control) Explained
9
+
10
+**FOC** is indeed a **driving method** (or algorithm) used by a **Motor Controller** to manage the current going into a BLDC motor. It is also professionally known as **Vector Control**.
11
+
12
+#### How it Compares to Other Methods:
13
+
14
+| Driving Method | Control Waveform | Performance | Noise Level |
15
+| :--- | :--- | :--- | :--- |
16
+| **Trapezoidal (6-Step)** | Blocky "On/Off" steps | Good for high speed, jerky at low speed | **Loud** (High-pitched whine) |
17
+| **Sinusoidal** | Smooth Sine waves | Smoother than Trapezoidal | Quiet |
18
+| **FOC (Vector)** | Precise mathematical alignment | **Highest Torque & Efficiency** | **Silent** |
