3 Phase Electric Motors
Phase Electric Motors Are More Efficient
most common type of 3
phase electrical load is the 3
phase electric motor.
A 3 phase motor is more compact and less costly than a
1-phase motor of the same voltage class and rating;
also 1-phase AC motors above 10 HP (7.5 kW) are not as
efficient and thus not usually manufactured.
3 phase induction motor has a simple design,
inherently high starting torque, and high efficiency.
Such motors are applied in industry for 3
phase pumps, fans, blowers, compressors, conveyor
drives, and many other types of 3 phase
motor-driven equipment. There are a lot of benefits to
using a 3 phase
electric motor over a single phase electric
air conditioning equipment (for example, most air
conditioning units above 2.5 tons (8.8 kW) cooling
capacity) use 3 phase motors for reasons of economy
and efficiency. Read more about other 3
phase power loads. Read more about 3
phase motors below.
electric power is distributed in the form of 3-phase AC.
Therefore, before proceeding any further you should
understand what is meant by 3 phase power. Basically,
the power company generators produce electricity by
rotating (3) coils or windings through a magnetic
field within the generator . These coils or windings
are spaced 120 degrees apart. As they rotate through
the magnetic field they generate power which is then
sent out on three (3) lines as in three-phase power. 3
phase transformers must have (3) coils or windings
connected in the proper sequence in order to match the
incoming power and therefore transform the power
company voltage to the level of voltage we need and
maintain the proper phasing or polarity.
Power Is More Efficient Than Single Phase
Three phase electricity powers large industrial loads more
efficiently than single-phase electricity. When
single-phase electricity is needed, It is available
between any two phases of a three-phase system, or in
some systems , between one of the phases and ground.
By the use of three conductors a 3 phase system can
provide 173% more power than the two conductors of a
single-phase system. Three-phase power allows heavy
duty industrial equipment to operate more smoothly and
efficiently. 3 phase power can be transmitted over
long distances with smaller conductor size.
