About this Calculator:
This free DC Motor Torque and Power Online Calculator helps you determine the required torque and power for your motor based on various inputs such as load weight, desired speed, wheel radius, efficiency, voltage, current, motor efficiency, gear ratio, and friction coefficient. By providing these inputs, you can calculate the necessary parameters to ensure your motor operates efficiently and meets your application's requirements.
Equations Used:
Torque (Nm): \( \tau = \frac{m \cdot g \cdot r}{\eta} \)
Power (W): \( P = \tau \cdot \omega \)
Motor Speed (RPM): \( \text{Motor Speed} = \text{Desired Speed} \cdot \text{Gear Ratio} \)
Motor Power (W): \( \text{Motor Power} = V \cdot I \cdot \eta_m \)
Mechanical Power (W): \( \text{Mechanical Power} = P \cdot \eta_m \)
Electrical Power (W): \( \text{Electrical Power} = V \cdot I \)
Total Efficiency (%): \( \text{Total Efficiency} = \left( \frac{\text{Mechanical Power}}{\text{Electrical Power}} \right) \cdot 100 \)
