|
| 121 | +## Why Is It Called a "230 Motor"? |
|
| 122 | + |
|
| 123 | +The name **"230 motor"** comes from an informal naming convention based on the **size of the motor case**, not the voltage or power. |
|
| 124 | + |
|
| 125 | +### 📐 Meaning of "230" |
|
| 126 | + |
|
| 127 | +- **"2"** = Series or form factor group |
|
| 128 | +- **"30"** = Approximate **length of the motor case in millimeters** (~30 mm) |
|
| 129 | + |
|
| 130 | +So, a **230 motor** typically has: |
|
| 131 | +- **Diameter:** ~24 mm |
|
| 132 | +- **Length:** ~30 mm |

|
| 61 | +### 🔧 Why Use a Gear Motor? |
|
| 62 | + |
|
| 63 | +| Feature | Effect | |
|
| 64 | +|------------------------|------------------------------------------------------| |
|
| 65 | +| **Lower speed (RPM)** | The gearbox reduces the motor’s high speed | |
|
| 66 | +| **Higher torque** | Gear reduction increases torque at the output shaft | |
|
| 67 | +| **Better control** | Easier to manage at low speeds (no stalling) | |
|
| 68 | +| **Compact design** | All-in-one motor + gearbox in one body | |
|
| 69 | + |
|
| 70 | +--- |
|
| 71 | + |
|
| 72 | +### 🔁 Example: |
|
| 73 | + |
|
| 74 | +- A regular DC motor might spin at **6000 RPM** |
|
| 75 | +- With a **50:1 gear ratio**, the output becomes **~120 RPM**, but with ~50× more torque (minus losses) |
|
| 76 | + |
|
| 77 | + |
|
| 78 | +If your 895 motor lacks torque even with a gearbox, consider: |
|
| 79 | + |
|
| 80 | +- High-torque 24V–36V gear motors, 300W–1000W |
|
| 81 | +- Brands: **Zhenlong**, **MY1016**, **E-Tek** |
|
| 82 | + |
|
| 83 | +**Use**: Robotics, automation, e-mobility, conveyor systems |

| 1 | +# Three-Phase BLDC Motor Data |
|
| 2 | + |
|
| 3 | +The common three thick motor wires (yellow, green, blue) found on electric scooters are actually: |
|
| 4 | + |
|
| 5 | +## ✅ Brushless DC Motor (BLDC) or Permanent Magnet Synchronous Motor (PMSM) |
|
| 6 | + |
|
| 7 | +Also known as: |
|
| 8 | + |
|
| 9 | +- Three-phase brushless motor |
|
| 10 | +- Hub Motor |
|
| 11 | +- Brushless DC Motor |
|
| 12 | + |
|
| 13 | +These three wires are the motor's three-phase power lines, used by the controller to drive the motor's rotation. |
|
| 14 | + |
|
| 15 | +## 🔍 Structure Features of Three-Wire Motors in Electric Scooters |
|
| 16 | + |
|
| 17 | +### 1️⃣ Three-phase windings (U / V / W phases) |
|
| 18 | + |
|
| 19 | +The usual colors are: yellow, green, blue |
|
| 20 | + |
|
| 21 | +These three phases are commutated in sequence to make the motor spin. |
|
| 22 | + |
|
| 23 | +### 2️⃣ Permanent magnet rotor (magnets inside the wheel) |
|
| 24 | + |
|
| 25 | +The center is the rotor (with magnets). |
|
| 26 | + |
|
| 27 | +Bicycles and scooters both use hub-type structures. |
|
| 28 | + |
|
| 29 | +### 3️⃣ Stator on the outer ring of the coil |
|
| 30 | + |
|
| 31 | +The motor is an outer rotor structure (the shell rotates). |
|
| 32 | + |
|
| 33 | +The stationary part is inside the coil. |
|
| 34 | + |
|
| 35 | +## ⚡ Why are there only three thick wires? Isn't that too few? |
|
| 36 | + |
|
| 37 | +It's not too few, because: |
|
| 38 | + |
|
| 39 | +These three wires are the power wires. |
|
| 40 | + |
|
| 41 | +Some motors also have Hall sensors (5 thin wires). |
|
| 42 | + |
|
| 43 | +Electric scooters usually have two types: |
|
| 44 | + |
|
| 45 | +| Type | Number of Wires | Features | |
|
| 46 | +|---------------------|------------------------|------------------------------------------| |
|
| 47 | +| Sensorless BLDC | Only 3 thick wires | Starts by induction, more vibration at low speed | |
|
| 48 | +| With Hall PMSM/BLDC | 3 thick + 5 thin wires | Smooth start, suitable for FOC control | |
|
| 49 | + |
|
| 50 | +## 🛴 Why do electric scooters use three-phase brushless motors? |
|
| 51 | + |
|
| 52 | +Because the advantages are obvious: |
|
| 53 | + |
|
| 54 | +- High torque |
|
| 55 | +- High efficiency |
|
| 56 | +- Silent operation |
|
| 57 | +- Maintenance-free (brushless, no wear) |
|
| 58 | +- Simple structure (directly integrated in the wheel) |
|
| 59 | + |
|
| 60 | +Almost all modern scooters (Xiaomi, Ninebot, Kaabo, etc.) use this type. |

| 56 | -## Definitions |
|
| 57 | - |
|
| 58 | -⚙️ A DC motor that has a gearbox (gear reduction unit) attached to it — usually on the output shaft. |

|
| 61 | -### 🔧 Why Use a Gear Motor? |
|
| 62 | - |
|
| 63 | -| Feature | Effect | |
|
| 64 | -|------------------------|------------------------------------------------------| |
|
| 65 | -| **Lower speed (RPM)** | The gearbox reduces the motor’s high speed | |
|
| 66 | -| **Higher torque** | Gear reduction increases torque at the output shaft | |
|
| 67 | -| **Better control** | Easier to manage at low speeds (no stalling) | |
|
| 68 | -| **Compact design** | All-in-one motor + gearbox in one body | |
|
| 69 | - |
|
| 70 | ---- |
|
| 71 | - |
|
| 72 | -### 🔁 Example: |
|
| 73 | - |
|
| 74 | -- A regular DC motor might spin at **6000 RPM** |
|
| 75 | -- With a **50:1 gear ratio**, the output becomes **~120 RPM**, but with ~50× more torque (minus losses) |
|
| 76 | - |
|
| 77 | - |
|
| 78 | -If your 895 motor lacks torque even with a gearbox, consider: |
|
| 79 | - |
|
| 80 | -- High-torque 24V–36V gear motors, 300W–1000W |
|
| 81 | -- Brands: **Zhenlong**, **MY1016**, **E-Tek** |
|
| 82 | - |
|
| 83 | -**Use**: Robotics, automation, e-mobility, conveyor systems |
