Unformatted text preview: of shaft rotation with the electromotive force constant Kb. The figure below shows the electromechanical model of a DC motor. Va(t) is the input voltage applied to the motor Ra is the armature resistance La is the armature inductance eb(t) is the back emf voltage (from the generator law) Kb is the back emf constant m is the motor shaft angle b represents friction in the motor Tm is the motor torque a. Write the equations of motion for this system (Hint: There will be one equation of motion for each of the laws above). Homework 3 Page 3 of 8 D...
