Calculate the following for two 20hp DC machines, one rated at 3500rpm and the other rated at 500rpm. Use data from the DC machines datasheet on the course website, including "hot" armature resistance value for all calculations. Note the machine constant K is proportional to the field flux, and the value on the datasheet is for rated (100%) flux. Both the load moment of inertia Jz and the viscous friction coefficient B are zero unless stated otherwise. Do not neglect the machine inertia Jm. ) Calculate the eigenvalues p and P (real or complex) for operation at rated flux and at 50% of rated flux.
