Some of them will do a 30 day trial, I used one to get a job done with a bldc project, and found it quite helpful. | |

All this can be forgotten for the time being, i've managed to calculate the guass strength at 3mm from the inner part of the ring to be -600 gauss(why -ve?). How do I calculate the electrcity induced given this field strength(or does one convert the field to Tesla?) given the RPM is about 500RPM, and the armature turns number 600? | |
