1. Technical Background
With the continuous advancement of industrial automation and intelligent manufacturing, the combination of servo motors and planetary gearboxes (servo motor gearbox / planetary gearbox for servo motor) has become the standard solution in motion control systems. Servo motors provide high precision and fast response, while planetary reducers amplify torque, reduce speed, and maintain long service life and high efficiency.
Market Reference:
-
Global servo motor and gearbox market projected to reach USD 9.5 billion by 2025.
-
Planetary reducers for servo motors account for more than 55% in high-end automation, due to high torque density, low backlash (≤3 arcmin), and high efficiency (≥97%).
2. Why Combine Servo Motor and Planetary Gearbox
| Parameter | Direct Servo Drive | Servo + Planetary Gearbox | Improvement |
|---|---|---|---|
| Output Torque | 1.3 Nm (400W) | 26 Nm (1:20 ratio) | ~20x |
| Positioning Accuracy | ±0.05 mm | ±0.03 mm | +40% |
| Max Speed | 3000 rpm | 150 rpm | Suitable for low-speed, high-torque |
| Lifetime | 10,000 h | 20,000 h | 2x |
| Backlash | 5 arcmin | ≤3 arcmin | Precision improvement |
Using a planetary gearbox for servo motor allows high-torque, low-speed output, essential for AGVs, robots, medical equipment, and intelligent logistics systems.
