Will you educate me on capacitors, please?
The motor on my saw hummed and would not turn under load. It did turn without belt attached. I called SCM service and talked with technician. Kudos to them, they called me an hour after I had submitted my support request. Diagnosis is to replace the capacitor. There only appears to be only one capacitor which was located outside the motor. I opened the box on the motor and only see wires, nothing else that looks like a capacitor. I plan to contact SCM on Monday for a replacement but am hedging my bets in case I need to replace with an aftermarket. I searched online for comparable but nothing matched exactly. Motor is 240v single phase. Capacitor has two wires coming out of it into the electric box on the motor. It is 1.75 inches in diameter and 4 inches long. The machine is a Minimax c26 genius multi-function machine, having three separate motors. So, my questions are:
- can only one capacitor act as both start and run capacitor?
- There are two voltages listed on the label (400v and 450v). Does the capacitor need to have those exact voltages or would 450v be sufficient.
- It is going to be a real challenge to get into the electric box because of the tight space, so I would like to cut the wires near the capacitor and just splice wires to the new one (when it comes). Any issue with doing this?
- other threads on this forum discussing capacitors indicated that one could go a little higher in micro farads. This one is 35uf, so how high could it go and still be a good replacement? Is that what +5% indicates?
- anything else to be aware of?
Thanks in advance,
Ralph
