Example 7.1 System with DC Motor

K2: Rotational spring constant of shaft numbered 2

Ra : Motor’s resistance

La : Motor’s inductance

Jm : Motor’s mass moment of inertia

Bm : Motor’s rotational damping coefficient

Ki : Motor’s torque constant

Kb : Motor’s back emf constant

Vk : Motor’s supply voltage

JL : Load’s mass moment of inertia

By : Rotational damping coefficient in bearings
