Hi,
I have a problem of increased brush wear on a 110VDC permag motor. The motor is driven by a DC/DC Single Output Converter.
The input to the converter is from a 48V battery and the output is supplied to the motor. The output rating of the converter is 125V 8A. The motor is operated intermittently for 10sec at a time and draws 6A typically.
This same type of motor has been used in similar situations for many many years with normal brush wear. The difference here is the DC/DC converter setup.
My question is what impact the converter could have on brush wear. Can different types of supply voltages (i.e. switchmode supplies like the converter mentioned) affect the DC motors brushes?
Thanks.
