THE DIS EAS ES OF
CHAPTER III.
SINGLE-PHASE AND POLYPHASE INDUCTION
MOTORS.
The rotor, i.e. the rotating part of the motor, .which
is often, but incorrectly, termed the armature, is the
only part of an induction motor of which the construc-
tion is different from that of the above described
single-phase and polyphase generators. The external
part, the fixed stator, which is really the stationary
armature of the motor, is exactly the same as the
stationary armatures of modern alternators. This
similarity is in the case of the larger sizes so exact
that the same patterns are used for the stators of
generators and induction-motors.
It is therefore useless to say anything extended
here concerning the faults which may occur in the
stator winding, since we have already noticed most of
them. We will therefore only consider some points
which are at any rate different in their external effect,
and which differ from those previously mentioned.
We must specially mention the single-phase motor,
