What is the voltage of a servo motor?
Servo motor voltages vary, but hobby servos commonly run on 4.8V to 7.4V DC, with standard being around 5V, while industrial types can use much higher AC or DC voltages (230V+ or up to 48V DC). Higher voltage boosts torque and speed but increases heat and current draw, so always check your servo's specs for its specific voltage range (e.g., 4.8-6V, 6-7.4V) to avoid damage.
Common Voltages
- Hobby/RC Servos: 4.8V (2-3 NiMH cells) to 7.4V (2 LiPo cells) is typical, with 5V or 6V being very common.
- Micro Servos: Can sometimes operate on lower voltages like 3V-4.8V.
- Industrial Servos: Can range from under 48V DC to high-voltage AC (230V+).
Key Considerations
- Torque & Speed:Higher voltage within the specified range increases torque (strength) and speed, but also current.
- Current (Amps):Current draw is critical; servos draw little when idle but much more under load, sometimes over 1 Amp.
- Signal Voltage:The control signal (PWM) is often 3.3V or 5V, but the power supply voltage is what drives the motor's strength.
- Check Specs:Always find the "Working Voltage" in the servo's datasheet to match your power supply to its requirements.

What is the torque of a servo motor?
What Torque Means
- Definition: Torque is a twisting force that causes rotation; think of it as the "strength" of the motor to turn something.
- Formula: (Torque = distance from axisapplied force).
- Units: Commonly Newton-meters (Nm), foot-pounds (lb-ft), or kilogram-centimeters (kg-cm).
Types of Torque
- Stall Torque: The maximum torque produced when the motor shaft is stopped (zero speed).
- Peak Torque (Mmax): The highest torque the motor can generate for very brief periods (milliseconds).
- Continuous Torque: The torque the motor can provide for sustained periods without overheating.
- Acceleration Torque: The torque needed to change speed (accelerate or decelerate).

YouTube · Dec 16, 2024
Key Factors & Calculations
- Torque Curve: Servo motors maintain relatively flat torque curves until high speeds, unlike stepper motors.
- Total Required Torque: Sums gravity, friction, and acceleration torques.
- Torque Constant (): Relates current to torque (e.g., Nm/Amp) and is derived from the voltage constant ().
This video provides a visual explanation of how servo motor torque and speed relate to each other:

Selection & Usage Tips
- Sizing:Choose a motor where its continuous torque exceeds the required torque, plus margins for acceleration and friction.
- Safety Margin:Operate servos well below stall torque (e.g., <30% of stall torque) to prevent damage and extend life.
