DC40 ERP brush bar motor (only) testing
« on: April 24, 2023, 04:09:55 pm »
Hi all
I have a dc40 erp model where the brush head bar is not turning but there is 240v coming through the duct assembly (spine/shaft) when tested. I have disassembled the motor from the housing to check, so my question is if I apply 240v directly to the motor itself, thus by-passing the wiring loom, should the motor turn? Cheers.

Should be 240v AC going into the PCB, then DC coming out, with the capacitor think the output is about 350v DC (cant remember the exact amount.)

Most of the fails I've had on these machines have been the yoke cable from the board to the fitting for the head, otherwise brush motor and sometimes the actual board itself.

Not really, its a DC motor and putting AC to it isn't advised.
