Which one of the following statements is correct for the ideal field excitation during starting in case of shunt and compound motors?
A. Maximum, because motor torque required to overcome friction and load torque.
B. Maximum, because voltage should be built slowly.
C. Maximum, because small excitation will lead low operating speed during starting.
D. It can be anything because it does not matter in case of these motors.
