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 rightt motor for specific applications. This guide provides reasforward metods to determinae these key reserters.

Calculating Stall Torque

Stall torque is th maximum torque a servo motor can produce when thee rotor is not rotating. It is typically specied by thee currer. To verify or estimate stall torque, use thor 's datasheet values or perforem a tett by appliying voltage and measuring thee torque with a torque sensor.

In cases where direct measurement is not possible, approate stall torque using thee motor 's rated current and torque constant:

CLAS1; CLAS1; CLAS3; CLAS3; Stall Torque (Nm) = Torque Constant (Nm / A) × Stall Current (A) CLAS1; CLAS1; CLAS1; CLAS3e: 1 CLAS3; CLAS3;

Calculating Peak Power

Peak power applis at a specic point during motor operation, often near the maximum torque at a given speed. To estimate peak power, use te formula:

CLAS1; CLAS1; CLAS3; CLAS3; CLAS3; Peak Power (W) = Torque (Nm) × Angelar Velocity (rad / s) CLAS1; CLAS1; CLAS1; CLAS3; CLAS3CCAS3CRAS3CLAS3CLAS3CLAS3CLAS3CLAS3CLAS3CLASPESSIORES;

Where angular velocity is calculated from the motor 's speed in revolutions per minute (RPM):

CLAS1; CLAS1; CLAS3; CLAS3; CLAS3; CLAS3; CLAS3c (RLAS3c) = (RPM × 2π) / 60 CLAS1; CLAS1; CLAS3c: 1 CLAS3d; CLAS3c;

Example Calculation

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:

CLAS1; CLAS1; CLAS3; CLAS3; Stall Torque = 0,1 Nm / A × 2 A = 0,2 Nm CLAS1; CLAS1; CLAS1; CLAS3e: 1 CLAS3; CLAS3e;

Next, convert RPM to rad / s:
