Both single-phase and polyphase AC motors are produced by LEESON
and many other manufacturers. In polyphase motors, the placement of
the phase winding groups in conjunction with the phase sequence of
the power supply line produces a rotating field around the rotor
surface.
The rotor tends to follow this rotating field with a rotational
speed that varies inversely with the number of poles wound into the
stator. Singlephase motors do not produce a rotating field at a
standstill, so a starter winding is added to give the effect of a
polyphase rotating field. Once the motor is running, the start
winding can be cut out of the circuit, and the motor will continue
to run on a rotating field that now exists due to the motion of the
rotor interacting with the single-phase stator magnetic field.

Answer 1
If arranged in a circle, the lights would appear to rotate. The
speed of this ”rotation” depends on the frequency of the on/off
blinking.
Follow-up question: what electrical change(s) would you have to
make to reverse the direction of the lights’ apparent motion?
Challenge question: what would happen to the apparent motion of the
lights if one of the phases (either 1, 2, or 3) were to fail, so
that none of the bulbs with that number would ever light up?
Answer 2
The compass needle would rotate. Challenge question: what would
happen to the apparent motion of the magnetic field if one of the
phases
(either 1, 2, or 3) were to fail, so that none of the coils with
that number would ever energize?
Answer 3
The magnetic rotor will rotate as it tries to orient itself with
the rotating magnetic field.
Follow-up question: what must we do with the AC power energizing
the coils to increase the rotor’s rotational speed?
