abnormal sound issue resolved by Team phynyx
The low speed of the generator (rotor) was maintained to observe to see if there were any abnormal sounds that were reported during the operation of the machine! After checking Team Phynyx replaced the bad quality brushes and brush holders and replaced them with our carbon brush holder SKU 72-58 series and carbon brush SKU 52-59.
Here is the clip of the slip ring in the generator! You can easily see the smooth working of Phynyx carbon brush and holders there. Inspection and maintenance of your motors and generators are very crucial!
