Winding, Disc.
A winding which (S. P. Thompson) may be treated as a drum winding
extended radially, the periphery corresponding to the back end of the
drum. The magnet poles are generally placed so as to face the side or
sides of the disc.
Winding, Lap.
A method of winding disc and drum armatures. It consists in lapping back
each lead of wire towards the preceding lead upon the commutator end of
the armature. Thus taking the letter U as the diagrammatical
representation of a turn of wire in connecting its ends to the
commutator bars they are brought towards each other so as to connect
with contiguous commutator bars. This carries out the principle of
keeping the two members of the U moving in regions of opposite polarity
of field, so that the currents induced in them shall have opposite
directions, thus producing a total current in one sense through the bent
wire.
Winding, Long Shunt.
A system of compound winding for dynamos and motors. The field is wound
in series and, in addition thereto, there is a shunt winding connected
across from terminal to terminal of the machine, and which may be
regarded either as a shunt to the outer circuit, or as a shunt to the
series-field and armature winding. (See Winding, Short Shunt.)
Synonyms--Series and Long Shunt Winding.
Winding, Multiple.
A winding of an electro-magnet, in which separate coils are wound on the
core, so that one or any number may be used as desired in parallel or in
series. For each coil a separate binding post should be provided.
Winding, Multipolar.
Winding adapted for armatures of multi-polar dynamos or motors.
Winding, Series.
A method of winding a generator or motor, in which one of the
commutator-brush connections is connected to the field-magnet winding;
the other end of the magnet winding connects with the outer circuit. The
other armature-brush connects with the other terminal of the outer
circuit.
Winding, Series and Separate Coil.
A method of automatic regulation applied to alternating current dynamos.
Winding, Short Shunt.
A method of compound winding for dynamos and motors. The field is wound
in series, and in addition thereto there is a shunt winding connected
from brush to brush only, thus paralleling the armature. (See Winding,
Long Shunt.)
Synonyms--Series and Short Shunt Winding.
