3 phase motor net magnetic field

Click For Summary

Discussion Overview

The discussion centers around understanding the net magnetic field produced by a three-phase motor when driven by a sinusoidal waveform. It explores the contributions of each phase to the overall magnetic field and seeks clarification on how to calculate or visualize the net magnetic field.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant inquires whether the magnetic field produced by each phase of a three-phase motor adds together to create a net magnetic field.
  • Another participant asserts that the net magnetic field is the vector sum of the contributions from each winding.
  • There is a request for examples or simulation tools to aid in understanding the concept more easily.
  • Some participants suggest that relevant details can be found in books on electrical machinery.

Areas of Agreement / Disagreement

There is no consensus on the best way to visualize or calculate the net magnetic field, and the discussion includes multiple viewpoints regarding resources for further understanding.

Contextual Notes

Some assumptions about the nature of the magnetic fields and the conditions under which they are summed may not be explicitly stated. The discussion does not resolve how to specifically calculate or simulate the net magnetic field.

I am trying to understand the basics of bldc motor. My question is if i am driving the 3 phase motor with sinusoidal waveform. The magnetic field is produced for each phase or it will add together to generate net magnetic field? How to get the net magnetic field.

The net field is simply the vector sum of all the field contributions from each winding.

Any examples or simulation tools available to understand them more easily.
 
Most books on electrical machinery will show this worked out in detail. Get a good book and read.
