Greetings
I have recently acquired a Hardinge UM Serial Number 20371 with an old (like the machine) 3 phase motor. Connected to a VFD with motor belt disconnected, the motor starter overload tripped immediately. Bypassing the starter connecting from the VFD directly to the barrel switch with no load the motor would operate forward and reverse fast and slow. With belt connected the motor would not start and tripped the house distribution panel 220 volt breaker. The shaft which connects by three belts to the spindle can be turned by hand by rotating the pulley. I removed the motor intending to test it or have it tested. It has no name/information plate and the wiring connections on the motor are not accessible. I have attached a picture of the mill and pictures of the motor.
I am seeking advice on how or whether to proceed with testing the motor and generally how to get the machine operational.
Thanks
