Why do you need to know?

beacause i have one and the inverter blow the igtb so i´ve decided to buy another inverter,
but i want to make sure that my spindle isnt burn..
i´ve measured it between the 3 pins and he has 2.1 ohms in each.
i´m from portugal and there isn´t much support on this area here...
thanks edgar
