Discharging and testing 2 large capacitors
<< < (3/3)
Gyro:
Those two values are a little unusual 40, 70 and 80uF are more common.

If you want branded ones, then CPC and Farnell sell Ducati, which is a decent brand. I checked RS but they have nothing cable terminated.

As often happens, CPC are cheaper than Farnell, even though they are the same company...

Carsey:
a 70uF will work ok?

The 70uf is a tiny bit smaller in diameter, but I should be able to tweak the bracket that holds it on no problem
Gyro:
Others will have a view, but the 80uF would give a little leeway for capacitance drop over time. I'm really not sure if a bit under or bit over is better in this case (start cap).

40uF instead of 37.5uF for the run cap sounds less but of course is the same in proportion.

Motor caps inevitably loose some capacitance over time due to self healing.
james_s:
Anything within +/-20% really ought to be fine, these are not precision components. You just don't want something drastically different. Most of the motors ive dealt with have the capacitors inside camel hump covers on the motor but if they mount externally you have a lot more leeway.
