My Proxxon Micromot 60 Drill Drill Went BANG!!!
It is easy to insert the power connector in reverse which causes the original 1uF Electrolytic Capacitor to go BANG!
Not only does this scare the life out of you is also means there is no suppression capacitor on the motor which results in a less smooth and noisy motor.
Simply replace the original capacitor with a high quality 100nf Polyester film or Ceramic Capacitor which are non-polarised (Also know as a 104 capacitor)
I found a 100nf capacitor to work best and this is a standard value for small DC motors.
Choosing a non-polarised capacitor will ensure that if you make the same mistake in future your Proxxon drill/grinder will simply rotate in reverse
