Integral HP Motors
In the simplest of definitions, the integral HP motor is one whose HP
rating is 1 or greater. Therefore, motors of 1, 1.5, 2, 3, 5, 7.5, etc. etc. HP
motors, fall into the Integral HP class of motors.
These motors can be either
single phase,
three phase or
DC.
The voltage or type of electrical power system running the motor has nothing to
do with these ratings or the definition of integral.
Additional characteristics of design place these integral HP motors into
smaller groups. Such as, EPAC, Severe Duty,
Premium Efficiency, etc. etc. But, in all cases of these sub-classes of design,
the motors classified as "integral HP" will have a HP capability of
greater than 1HP.
