Servo motors are widely used in automation and robotics for precise control of movement. Understanding how to calculate stall torque and peak power is essential for selecting thee right motor for specific applications. This guidee provides experforward methods to determinate these key parameters.
Calculating Stall Torque
Stall torque is the maximum torque a servo motor can produce whene thee rotor is not rotating. It i s typically specified by the equirer. To verify or estimate stall torque, use te motor 's datasheet values or perperform a tett by appliying voltage and measururing the tore with a torque sensor.
Nie ma sprawy, gdzie można wycenić i nie ma możliwości, przybliżone stado torque using thee motor 's rated current and torque constant:
Xi1; Xi1; FLT: 0 Xi3; Xi3; Xi3; Xi3 = Xi3; Xi3; Xi3;
Kalkulator Peak Power
Peak power events at a specific point during motor operation, often near thee maximum torque at a given speed. To estimate peak power, use thee formula:
Xi1; Xi1; FLT: 0 Xi3; Xi3; Peak Power (W) = Torque (Nm) × Angular Velocity (rad / s) Xi1; Xi1; FLT: 1 Xi3; Xi3;
Kiedy Angular velocity is calculated frem thee motor 's speed in revolutions per minute (RPM):
Xi1; Xi1; FLT: 0 Xi3; Xi3; Angular Velocity (rad / s) = (RPM × 2mbH) / 60 Xi1; Xi1; FLT: 1 Xi3; Xi3; Xi3;

Suppose a servo motor has a torque constant of 0.1 Nm / A, a stall current of 2 A, and operates at 3000 RPM at peak power. First, calculate stall torque:
Xi1; Xi1; FLT: 0 Xi3; Xi3; Xi3; Xi3 = 0,1 Nm / A × 2 A = 0,2 Nm Xi1; Xi1; FLT: 1 Xi3; Xi3; Xi3;
Next, convert RPM to rad / s:
Xi1; Xi1; FLT: 0 Xi3; Xi3; Angular Velocity = (3000 × 2mbH) / 60 Xi314.16 rad / s Xi1; Xi1; FLT: 1 Xi3; Xi3; Xi3;
Finally, calculate peak power:
Xi1; Xi1; FLT: 0 Xi3; Xi3; Peak Poser = 0.2 Nm × 314.16 rad / s Xi62.83 W Xi1; Xi1; FLT: 1 Xi3; Xi3;
