I came across an equation for the Speed ω in Radians/seconds of a Cumulative Compound DC motor.
ω= K(V_{t}I_{A}[R_{A}+R_{F})/([itex]\Phi[/itex]_{P}+[itex]\Phi[/itex]_{S})

Maybe you should explain your formula and the used variables, or at least give its source.
My guess: K is some constant given by the geometry of the motor.
