DC NOISE MEASUREMENTS ON A PERMANENT MAGNET MOTOR USED AS A GENERATOR

MODEL: MY1020B 24V, 4 POLE, 27MPS 

MY1020B Permanent Magnet Motor noise measurements

 

NOW LOOK AT HOW SMOOTH THE DATA OUTPUT IS WHEN A 4 FARAD CAPACITOR IS ADDED:

GENERATOR NOISE TEST – NO LOAD- 4 Farad capacitor Test

1020B 24V 27 Amps 500W 2017 RPM, 4 Farad Capacitor With 24V Rating

A – 4 Farad cap first connected – charges up
B- 2 Seconds later Cap is disconnected
C- Cap is reconnected again for 3 seconds (350mV Peak to Peak Ripple)
D- 5 seconds alter cap is disconnected

Using a 4 Farad Capacitor to filter pm motor bicycle generator output voltage

NOTE: THIS DATA REPRESENTS GENERATOR VOLTAGE WITH A 4 FARAD CAPACITOR ON

THE OUTPUT TERMINALS WHICH MAKES THE DATA LOOK VERY STABLE

AND QUIET.  IT IS NORMALLY VERY NOISY LIKE THIS DATA SHOWN HERE
