In custom BLDC motor design some customers request or require “non-standard” feedback methods. In these cases it is required to determine an acceptable location for the position of the sensors, based on magnetic field distribution.
This is a simple case study look at determining an acceptable sensor location. In this case study the position of linear hall sensors will be considered. Acceptable positioning will be determined by acceptably high output from the linear hall cell and acceptably low harmonic distortion in the wave form.
