Abstract :
A novel method for diagnostic of the BLDC motor magnetic saturation is proposed. It comprises of analog amplifier in the role of pure sinusoidal current source, measurement subsystem and proposed acquisition which reliably detects signal asymmetry which is directly correlated with coil saturation. Practical experimental results are presented as proof of concept with several different current excitation levels.
