The 3 phase electric motor is usually a large piece of equipment that uses a “polyphase” circuit to draw heavy power loads at relatively low voltages. This improves power line efficiency and provides the smooth power flow required by many such motors. The cost of electricity for electric motor 3 …

Power Factor Calculation. We discussed that the efficiency of power system depends on power factor and to improve effective usage of power in a power system the power factor has to be improved. But, before that we must know the power factor of power system, , we must know the power factor calculation.

Similarly, Fullload Current, sometimes abbreviated as I fullload is the current required for an AC induction motor to run with its maximum load or rated power. The measurement unit for current is Amperes often used as amps. Formulas to calculate 3 phase AC induction motor …

Step by step motor calculations through pictures I took on the job and relating them to the Master and Journeyman electrician test. There is a lot of Motor Calculations on the Electrical Exam so check back for more Caculations.

If you can measure the voltage and amps flowing into the motor leads: (single phase) Amps x volts = VA, assume the Power factor is so the KW is (VA/1000) x on three phase, assuming balanced line currents, multiply by sq rt 3 (). That ...

In this page we are presenting online fan shaft power based on input parameter like air flow, total pressure and fan efficiency this is fan shaft power and no motor efficiency and other factor consider, in different industry actual power consumption of fan may change due to other factor like venturi or diffuser etc. so this is just a basic calculation based on airflow and total pressure you ...

The power factor of an AC electric power system is defined as the ratio active (true or real) power to apparent power, where. Active (Real or True) Power is measured in watts (W) and is the power drawn by the electrical resistance of a system doing useful work; Apparent Power is measured in voltamperes (VA) and is the voltage on an AC system multiplied by all the current that flows in it.

For a 1phase supply with power rating in kilowatt (kW): For a 1phase supply with power rating in horsepower (hp): Note that the motor rated full load current is specified on the motor datasheet and stamped on the motor nameplate. However, this calculator is useful when only the motor rating is available and an estimate of the current is required.
