I have an old 5 HP 3 phase motor that I have been using to run my 1940s Sebastian lathe and 1983 Bridgeport Mill. It is the basic old school set up that requires me to use a rope to start it. I have been using this setup for almost 20 years with no issues. Yesterday I went to start it and it took a little more effort to get it started but it started and sounded like it was a full speed but my mill and lathe were way down on power. I am very limited in my electrical knowledge. So is it possible for the motor to run but not supply full power to my machines? Any help is greatly appreciated.
