With reference to example 179 assume that the load torque, Ask an Expert

Engineering

With reference to Example 17.9, assume that the load torque applied to the PM DC motor is zero. Determine the response of the motor to a step change in input voltage. Derive expressions for the natural frequency and damping ratio of the second order system. What determines whether the system is over or under damped?

EXAMPLE 17.9

Dynamic Response of PM DC Motor Problem Develop a set of differential equations and a transfer function describing the dynamic response of the motor angular velocity of a PM DC motor connected to a mechanical load.
