Hello
I am building a dynamometer for brushless based on automotive alternator. I am using small motor but some friend are asking me to fit bigger motor.
I have removed diodes and i have solder 3 phases together. then i have removed regulator and i excite coil directly, it works perfect!
seeing it works, i thought about convert it in a true eddy current brake, I made this experience some time ago (i have no pictures!), i replaced the stator for masive iron lathe part. It surprised to me than it DON'T work!,
There are any secret, iron material have to be special? any idea about why it didn't work?
Thanks
