Compound DC motor shunt and series two of excitation windings. If the series winding magnetic flux of potential and flux of excitation winding potential directions the same as cumulative compound excitation. If two potential magnetic flux in the opposite direction, it is called a differential compound.
Different excitation modes DC motors have different characteristics. Main excitation modes of General DC motors are parallel, series type and compound type, the main DC generator excitation modes are excited, shunt and compound excitation type.
