Following an ESC burnout, I decided to check the inductance measurements of all my motors. The motors are T-motor AntiGravity 4006 380KV, with 18 coils (I can’t find any data for what the inductance of these should be).
I’m getting these sorts numbers for 4 of my motors
Phase A-B: 96.3 uH
Phase A-C: 84.4 uH
Phase B-C: 97.3 uH
So on all of the motors, the maximum variation of inductance across phases is about 12-15%. Unfortunately I don’t have any motors that I know for certain are okay, so I was just wondering what anyone makes of these numbers?
Any opinions much appreciated.
