Dear Members and Visitors,
The blog is now under development which allows a better user's experience and a better arrangement of our courses and materials. so, some of the links will not work during this period and we are sorry for that. please, keep following for the new Release of our blog very soon. thank you for your great support.

Electrical Calculations Sheet -Motor


                          


    NEMA Motor Data Calculator


This spreadsheets can make calculations for the following:

First : motors data

For single phase motor:
1-select the horse power rating
2- you will get the results for 115V and for 230V single phase voltage, the results will be as follows:

  • Full Load Amps (FLA)
  • Wire Size
  • Thermal Breaker Size
  • Breaker Cat No.
  • HD Switch Nema 1 Enclosed
  • Dual Elem Time Delay Fuse Amps
  • Fractional HP N1 Starter Class 2510
  • Thermal Unit
  • Integral Starter N1 Enc 2510
  • One Melting Alloy Thermal Unit
  • NEMA Enclosed Starter Class 8536
  • Thermal Unit

For three phase motor:
1-select the voltage
2- select the horse power rating
3-you will get the following results:

  • Full Load Amps (FLA)
  • Wire Size
  • Thermal Breaker Size
  • Breaker Cat No.
  • HD Switch Nema 1 Enclosed
  • Dual Elem Time Delay Fuse Amps
  • Nema Starter Catalog Number
  • Melting Alloy Thermal Unit
  • Nema Size Starter


Second: Transformer Data

1-Enter the KVA and Voltage
2-get three-phase and single-phase currents




Third: wire and conduit data
1-select the wire size
2- get the conduit size for different circuit configurations for both copper and aluminum wires

Forth : voltage drop data
1-Select wire size as before.
2- Enter the cable run distance in multiples of 100 ft.
3- Enter the amperage you will be drawing through the wire.
4- View the voltage drop for single and three phase based on PF.
