Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.

QUESTION 1 Consider the equations of motion of an armature controlled DC motor given by Jw(t)+bw (t) Ki (t) = di (l) L + Ri (t) + Kw (t) = -Tfriction - Tload (t) Vin (t), dt where vin(t) is the input voltage and Tload(t) is the input load torque. The outputs are the armature current i(t) and the motor speed w(t). When the input voltage and torque are constant, the transient response of this system has the form of the homogeneous solution. What is the time constant of the transient response? Find the characteristic roots of this system first. Keep 3 significant figures, and do not include units. Use scientific notation. The constants are given below: Nominal voltage, Vin(t) = 17 V Moment of inertia of the rotor, J = 0.02 kg-m² Motor viscous friction constant, b = 0.009 N-m-s Friction torque, Tfric = 0.003 N-m Armature inductance, L = 0.1 H Armature resistance, R = 0.35 Back emf constant and motor torque constant, K = 0.21 N-m/A. **Recall that the time constant (or relaxation time) is…
A multi plate friction clutch is used to transmit the power from the engine to a rotor which has a mass of 152 kg and a radius of gyration of 0.34 m. The inner and outer radius of the clutch disc is 0.055 m and 0.217 m respectively. The clutch plate has 4 contact surfaces (n = 4) and the axial thrust is 379 N. The flywheel of the engine rotates constantly at 1,106 rpm. Calculate the time required to accelerate the rotor from rest if the clutch is suddenly engaged. Take μ = 0.42. Assume uniform wear in clutch.
