Physics · Electrical Drives
For the dynamics of electrical drives, where Tm(t) is motor torque, TL(t) is load torque, J is moment of inertia, and ω is angular velocity, the following statements are given: (A) For Tm(t) TL(t), dωdt > 0, speed increases (C) For Tm(t) = TL(t), dωdt = 0, the drive attains a steady state (D) The fundamental torque equation is Jdωdt + ω22dJdα = Tm(t) − TL(t) (E) The fundamental torque equation for constant inertia is Jdωdt = Tm(t) − TL(t) Choose the correct answer from the options given below:
