Motor loads calculation - Electrical Engineering

Electrical motor loads are calculated from power in kW and full rated load in kW.Following is the formula how to calculate Motor loads. Example : We have 1 unit Induction Motor with 30 horsepower (hp),running with 34.9 amps for amperage load and 460 volts 3 phase and power factor value is 0.75 and motor efficiency is 85% . STEP 1. We determine value of power in kW (Pi) using this formula. STEP

How to Determine Speed for an Ac Induction

Illustration of a six-pole stator. One way an hvacr service tech can determine that s/he is making good motor replacement decisions in the field is to understand the concept of motor speed so that the speed of one ac induction motor can be matched to another. At the same time, techs also need to become familiar with the concept of poles, since poles represent one key to a successful replacement.
