A DC motor is driving a load given by TL = 3 + 0.02ωLNm , where ωL is the speed in rad/sec. The armature resistance of the motor, Ra = 2Ω . The machine constants at rated flux density, kE=kT=0.4 (inSIunits). It is required to maintain ωL =100rad/sec
(a) Calculate the required armature voltage at rated flux density
(b) Calculate the required armature voltage if the flux density is 80% of the rated value.
