9.13.1 General Characteristics
A synchronous electrical motor is an AC motor in which,
the rotation of the shaft is synchronized with the frequency
of the supply current when at a steady state. The rotation
period is exactly equal to an integral number of AC cycles.
Synchronous motors contain electromagnets on the stator
of the motor that create a magnetic field, which rotates in
time with the oscillations of the line current. The rotor with
permanent magnets or electromagnets turns in step with
the stator field at the same rate and as a result, the rotor
provides the second synchronized rotating magnet field of
any AC motor.
It is possible to get an idea of the efficiency of the motor by
measuring the resistance of the coils: 6 to 8 ohm (contacts
Z-Y), 6 ohm to 8 ohm (contacts X-Y), 6 to 8 ohm (contacts
X-Z).
