I have a bench drill which I didn't use for many years, and was stored outside under cover. It now generates insufficient power to drive the belt, although I can get the motor to run by manually spinning the pulley on the shaft. I haven't looked inside the casing of the motor, but it runs quite freely under no load. I saw an internet video which suggested that the capacitor is at fault. I took that off, and the motor still starts by hand and runs, so I will try a new capacitor.
It is a type CBB60 SH, 6.5uF (+/- 5% Class B, if that is relevant) 450V AC 50/60Hz.
I see on Lazada a lot of capacitors for fans, some rated at 6uF and 8uF. There are also some designated CBB60, seem to be for washing machines and the like. The nearest on offer is 6.3uF, then 8uF.
My two questions are:- 1) Will the 6.3uF work ok? 2) Is there any advantage or danger to fitting 8uF?
I have a very feeble grasp of matters electric, so simple explanations would be appreciated.
