Chapter 6, Problem 6.44P

A conveyor drive system to produce translation of the load is shown in Figure P6.44. Suppose that the equivalent inertia felt at the motor shaft is 0.05 kg m 2 , and that the effect of Coulomb friction in the system produces an opposing torque of 3.6 N m at the motor shaft. Neglect damping in the system. It is desired to have the motor shaft rotate through 11 revolutions in a total time of 3 s, using a trapezoidal speed profile with t 1 = 0.5 s and t 2 = 2.5 s .

The given motor parameters are R a = 3 Ω , L a = 4 × 10 3 H , and K T = 0.4 N m/A . Compute the energy consumption per cycle; the maximum required torque, current, and voltage; the rms torque; and the rms current.
