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.
