Yesterday one of the start caps on my Anderson 7.5HP RPC blew up.
I'm not sure it if was just starting the idler motor or when the attached lathe started. I have replaced the capacitor and the idler now starts normally. The combination did work for the past 5-6 months.
The lathe is a '43 Monarch 10EE with a motor-generator drive. The AC motor is ~ 6HP and drives a DC generator. The generator output is not used until the spindle is started, driven by a 3HP DC motor. The lathe is not powered on until the RPC is running, so I wouldn't think that the start caps should be in the circuit when the lathe is supplying load.
Any ideas on why the cap would blow?
