convert a slip ring motor into a variable voltage transformer? 4

[ankervik]

Someone told me it is possible to convert a slip ring motor into a variable voltage transformer? If so what would be the set-up? We often have problems running up larger AC induction motors unloaded (380v/50Hz). Our present test bench doesn't cope too well when running motors over 250kw
