Maximum Torque in an Induction Motor Calculator

Maximum Torque in an Induction Motor Calculator

Calculate the maximum (breakdown) torque using the equation:
\[ T_{max} = \frac{3\,V^2}{2\,\omega_s\,(X_1+X_{2}’)} \] where \(\omega_s = 2\pi f\) is the synchronous angular frequency.

* Enter all values in SI units.

Step 1: Enter Parameters

Example: 230 V

Example: 50 Hz

Example: 1 Ω

Example: 0.5 Ω

Formula: \( T_{max} = \frac{3\,V^2}{2\,(2\pi f)(X_1+X_{2}’)} \)


Practical Example:
For a supply voltage of 230 V, frequency of 50 Hz, \(X_1 = 1\) Ω, and \(X_{2}’ = 0.5\) Ω:
\[ \omega_s = 2\pi \times 50 \approx 314.16 \, \text{rad/s}, \] \[ T_{max} \approx \frac{3 \times 230^2}{2 \times 314.16 \times (1 + 0.5)} \approx \frac{3 \times 52900}{2 \times 314.16 \times 1.5} \approx \frac{158700}{942.48} \approx 168.4 \, \text{N·m}. \]
