Product Details
The SG90 servo motor is one of the most popular and smallest servo motors available, commonly used in hobby electronics, robotics, and small mechanical projects. The "180 degrees" refers to its typical range of motion.
Key Specifications of the SG90 Servo Motor
| Feature | Specification | Description |
| Rotation Angle | 0 to 180 | This is its maximum arc of movement. Some versions may have a slightly different range. |
| Operating Voltage | 4.8V to 6V (approx 5V nominal) | Standard operating voltage. Connecting it to a 12 V source will damage it. |
| Torque | approx 1.5kg\cm to 1.8kg\cm | This is a low-torque motor, suitable for very light loads. |
| Speed | approx 0.1 sec per 60 | A relatively slow-speed motor. |
| Gears | Nylon (plastic) gears | This is typical of the SG90, which contributes to its low cost and light weight. |
| Control | Pulse Width Modulation (PWM) | Controlled by a PWM signal, usually generated by a microcontroller like an Arduino. |
Controlling the 180 Rotation
The SG90 is a standard analog servo motor controlled by a PWM signal on its signal wire (usually orange or yellow). The width of the pulse determines the angular position of the shaft.
| Pulse Width | Angle (Typical) |
| 1.0ms) | approx 0(Minimum position) |
| 1.5ms) | approx 90 (Center position) |
| 2.0ms) | approx 180 (Maximum position) |
The PWM signal is typically sent at a frequency of 50Hz (a pulse every 20ms).
Pinout and Wiring
The SG90 has three wires, which are typically color-coded:
Brown/Black:Ground (GND)
Red:Power (VCC), typically 5V
Orange/Yellow:Signal/Control (PWM input)
