1. 45T / 55T Motors
- "T" = Turns of wire on the motor armature.
- Higher T (e.g., 55T) = More torque, lower speed.
- Lower T (e.g., 12T) = Higher speed, lower torque.
- Typically 540-size brushed motors.
- Commonly used in RC crawling/trailing for torque and control.
- A 45T motor has 45 wraps (turns) of copper wire around each pole of the armature.
- The number of turns affects the motor's speed and torque.
Series = 19T / 21T / 27T / 35T / 45T / 55T / 60T / 80T
Summary Table
| Spec | 45T / 55T Motor | 130 / 230 Motor |
|---|---|---|
| Type | Brushed RC Motor | Toy motor |
| Size | 540-class | Small can-type |
| Torque | High (esp. 55T) | Low |
| Speed | Low (esp. 55T) | Moderate |
| Usage | RC crawling, trailing | Toys, fans, small gadgets |
🔧 Approximate Torque Value
- Torque (stall): ~300 to 400 g·cm (gram-centimeter)
- At 7.2V to 7.4V (common RC voltage)
⚠️ Note: This is an estimate. Some high-end 45T motors may produce more torque.

130 Motor Overview
The 130 motor is a type of DC motor commonly used in toys, small appliances, and DIY electronics projects.
🔧 Type
- Type: Permanent Magnet Brushed DC Motor
- Category: Small-size DC Motor
⚙️ Specifications (Typical)
- Voltage Range: 1.5V – 6V (Commonly 3V or 5V) ??? try up to 7V
- High RPM: Often from a few thousand to over 10,000 RPM
- Low Torque: Suitable for light-load applications
- Brush Type: Brushed (uses carbon brushes and a commutator)
230 Motor Overview
The 230 motor is a small DC motor, similar in design to the 130 motor but typically larger in size and power.
🔧 Type
- Type: Permanent Magnet Brushed DC Motor
- Category: Medium-size DC Motor
⚙️ Specifications (Typical)
- Voltage Range: Often 3V – 12V
- Higher Torque and Power than 130 motor
- Medium RPM (usually lower than 130 motor, but stronger)
- Brush Type: Brushed (uses carbon brushes)
Why Is It Called a "230 Motor"?
The name "230 motor" comes from an informal naming convention based on the size of the motor case, not the voltage or power.
📐 Meaning of "230"
- "2" = Series or form factor group
- "30" = Approximate length of the motor case in millimeters (~30 mm)
So, a 230 motor typically has:
- Diameter: ~24 mm
- Length: ~30 mm

🔧 Basic Requirements to Drive an 895 Motor
| Item | Purpose | Example |
|---|---|---|
| Power Supply | Feeds the motor with appropriate voltage/current | 12V–36V DC, 10–30A depending on load |
| Motor Driver / Controller | Controls speed and direction | H-Bridge (e.g., BTS7960, VNH2SP30), PWM controller |
| PWM Signal (optional) | Varies motor speed via duty cycle | From Arduino, Raspberry Pi, or ESC |
| Heat Dissipation | Prevents overheating during operation | Heatsinks, cooling fans |
