Three phase or polyphase induction
motors have high starting torque,
power factor, high efficiency and low
current. They do not use a switch,
capacitor, relays etc. , and are
suitable for use on larger commercial
and industrial applications. General
purpose, three phase motors have
different electrical designs
classifications as defined by NEMA.
NEMA Design C motors have higher
starting torque with normal starting
current. Both types have slip of less
than 5%. ("Slip" being a term which
expresses, as a percentage, the
difference between synchronous
motor speed and full load motor
speed, for example, 1800 rpm
synchronous versus a full load speed
of 1740 rpm.
AC Electric Motor - Three Phase Motors
The improvement of the light bulb came when they evenly spread the three phases across line frequency operated light
sources so that the Illuminated area provided light from all three phases. Through this process, the "Flickering" we use to
experience, with the old technology, no longer exists.  That same premise exists In the Three phase motor.  The Three
Phase AC Electric Motor, has a basic design, with high starting torque and
high efficiency.  The Three Phase AC Electric
Motor is shorter and cost less than a Single Phase AC Electric Motor of the same HP, voltage.  Another benefit of this
Three phase technology is that there is less vibration.  With less vibration the Three Phase AC Electric Motor will run at a
higher efficiency rate and the life of the motor will be longer that the Single Phase AC Electric Motor.
