The given circuit is of a DC shunt motor.
In a DC motor, the input is electrical and the output is mechanical.
Electrical Input = Mechanical Output + Losses
Mechanical Output = Electrical Input - Losses
Explanation
Electrical Input = VIa
Armature Losses = Ia2R
\(Mechanical \space Power = \mathrm{V} \mathrm{I}_{\mathrm{a}}-\mathrm{I}_{\mathrm{a}}^{2} \mathrm{R}_{\mathrm{a}}\)
