3 Terms and Definitions
3.1 General Terms
411-31-01
(electrical) rotating machine
an electrical apparatus depending on electromagnetic induction for its operation and having components capable of relative rotary movement and intended for converting energy
Note: This term also applies to electrical apparatus operating on the same principle and similar construction and intended for other purposes. E.g. regulation, supplying or absorbing reactive power. It is not intended to cover electrostatic machines.
411-31-02
homopolar machine
a machine in which the magnetic flux passes in the same direction from one member to the other over the whole area of a single air-gap
411-31-03
acyclic machine
a direct current homopolar machine
411-31-04
heteropolar machine
a machine having successive physical or effective poles of opposite polarity
411-31-05
direct current machine; d. c. machine
a machine incorporating an armature winding connected via a commutator to a direct current system and having magnetic poles which are excited from a source of direct or undulating current or which are permanent magnets
