Frequently Asked Questions (FAQs)

1. What gears are used in servo motors?

Servo motors commonly use coaxial gear units/planetary gear units and right-angle gear units/helical-bevel gear units. Planetary servo gear units transmit force coaxially, enabling high speeds, precision, torsional rigidity, and low backlash.

2. What is the gear ratio of RC servo?

The gear ratio of an RC servo is typically 180:1. This means that the DC motor shaft needs to rotate 180 times to produce 1 revolution of the servo shaft. The large gear reduction allows for precise positioning control.

3. Do servos have gears?

Yes, servos have gears. The gears in servos enable high speeds, accelerations, and precision in positioning and rotational speed. They also offer high torsional rigidity and low backlash, meeting the requirements of dynamic applications.

4. Is a higher kg servo better?

A higher kg servo indicates more torque force that the servo can exert. The torque force is measured in ounce inches (oz-in) or kilogram centimeters (kg-cm) and listed in the servo specifications. Choosing the correct servo strength based on the RC application is essential.

5. What is the standard servo gear size?

The standard size of a servo is approximately 40mm in length, 38mm in height, and 20mm in width. These dimensions are common for standard size servos.

6. Do servo motors need a gearbox?

Yes, servo motors usually include a gearbox as part of their construction. The gearbox is responsible for providing powerful and precise positioning control. It is typically combined with an electric motor, a potentiometer, a small control board, and an output shaft.

7. Why use gearbox with servo?

Using a gearbox in a servo system has several benefits, including reducing the inertia of the load. The gear ratio of the gearbox reduces the load inertia reflected to the motor. Even a small gear reduction can have a significant effect on the inertia ratio, improving the overall performance of the servo system.

8. How much torque does a 35kg servo have?

A 35kg waterproof servo can exert a maximum torque of up to 35 kg/cm at 7V. It is designed for high torque applications and is compatible with 1/8, 1/10, 1/12 trucks, RC cars, robots, and boats.
