How to Use This Calculator

Enter the stall torque (kg·cm) and operating voltage (V) for your servo motor.
Set the number of servos and expected duty cycle (%) for your application.
Enter speed (sec/60°) to characterize performance.
Review stall current (mA), average operating current, idle current, and power consumption (W).
Use these values to correctly size your power supply for the servo system.
