Consider a permanent-magnet DC motor with the following parameters: Trated = 10N. m, nrated = 3700 rpm; Torque constant k = 0.5 N.m/A, back emf constant k = Armature winding resistance is R = 0.37.2; m a 53V 1000rpm' Mechanical time constant = 11.7ms, electrical time constant Te = 4.05ms; Calculate the terminal voltage in steady state if the motor is required to deliver a torque of 5N.m at speed of 1500rpm,.
