What is a metal steering gear?
Metal steering gear is a precision actuator widely used in remote control models, robots, drones and other fields. Its core function is to convert electrical signals into precise mechanical movements. Compared to plastic gear servos, metal servos are preferred for high-performance applications due to their high strength and durability. The following is a detailed introduction to metal servos and an analysis of hot topics on the Internet in the past 10 days.
1. Core features of metal steering gear
The main advantages of metal servos are their construction and materials:
| Features | Description |
|---|---|
| Gear material | Using aluminum alloy or steel gears with stronger wear resistance |
| Torque output | Usually 30%-50% higher than plastic gear servos |
| Service life | It can reach more than 100,000 cycles, far exceeding that of plastic servos. |
| Applicable scenarios | Scenarios with high load and high precision requirements (such as racing drones, industrial robots) |
2. Working principle of metal steering gear
The metal servo achieves motion control through the following steps:
| steps | Description |
|---|---|
| 1. Signal input | Receive PWM (Pulse Width Modulation) signal |
| 2. Motor drive | Built-in DC motor rotates based on signal strength |
| 3. Gear transmission | Metal gear set amplifies torque and reduces RPM |
| 4. Position feedback | Potentiometer or encoder to correct angle in real time |
