Consider the single-coil rotor of Example 3.1. Assume the rotor winding to be carrying a constant current

Question:

Consider the single-coil rotor of Example 3.1. Assume the rotor winding to be carrying a constant current of I = 8 A and the rotor to have a moment of inertia J = 0.0125 kg ∙ m2.

a. Find the equilibrium position of the rotor. Is it stable?

b. Write the dynamic equations for the system.

c. Find the natural frequency in hertz for incremental rotor motion around this equilibrium position.
