Self-Excited Shunt DC Motor Calculator

    Self-Excited Shunt DC Motor Calculator

    Calculate key parameters for a self-excited shunt DC motor.

    The motor is modeled using:
    Field Current: \( I_f = \frac{V}{R_f} \)
    Effective Flux: \( \phi = k_f \times I_f \)
    Back EMF: \( E_b = V – I_a R_a \)
    Motor Speed: \( \omega = \frac{E_b}{k \phi} \)
    Developed Torque: \( T = k \phi I_a \)

    * Enter values in SI units.

    Step 1: Enter Motor Parameters

    Example: 220 V

    Example: 1000 Ω

    Example: 0.5 Ω

    Example: 10 A

    Example: 0.05 V/(rad/s·Wb)

    Example: 0.0005 Wb/A

    Key Formulas:
    \( I_f = \frac{V}{R_f} \)
    \( \phi = k_f \, I_f \)
    \( E_b = V – I_a \, R_a \)
    \( \omega = \frac{E_b}{k\,\phi} \)
    \( T = k \, \phi \, I_a \)
