Today I dropped the motor off at Newton Tesla and had a chat to the proprietor about how the motor could be reconfigured. He mentioned that older motors didn’t have the regular 3 phase Delta and Star configurations exposed externally, but internally they most probably do. So, I dropped off the motor for him to look at and will pick it up again as soon as it’s been rewired.
I also borrowed a switch blank from Newton Tesla to check if it would fit the switch on my lathe (as it was made for the Graduate) and luckily it fitted a treat. I’ll return the blank when I go to pickup the motor as I’ll be purchasing a three phase inverter and switchgear at the same time.
