DEFINITION
Classification: 318/248
(under subclass 246) Subject matter in which two or more immediate sources of e.m.f. are provided to supply electric energy to the conducting elements of a series motor.
(1) Note. Two sources of e. m. f. connected in series opposition in the circuit of a motor winding are included herein. Two circuits from a single voltage divider or from spaced sets of brushes on a single generator commutator, are examples of sources of electro-motive-force included herein.
