I have an old Bosch 3 phase brushless motor from a Washing Machine and its working Inverter board, now I know I could buy a VFD and control the motor that way but I was wondering if anyone has had luck connecting an arduino to a washing machine inverter board and controlling the motor? The invertors brains is 256mc206 microchip and the pins are
Thanks for the reply, I have looked at most of these videos and they concentrate mostly on Brushed Universal Motors which is a different type of motor to a BLDC motor unfortunately, the few for BLDCs are using either a VFD or there own design electronics.
As the 256mc206 is presumably actually a PIC33EP256mc206, it's a DSC micro-controller, so what it does, and how it's interfaced, is entirely dependent on the software it's running?.
Assuming this is just the motor controller?, then it must receive instructions from the main controller (and presumably sends replies back?), then you need to reverse engineer that communication.
Do you have the rest of the working control system so you can monitor the communication?.
I don't unfortunately, just the inverter and motor that was scrapped from the washing machine, I have lots of both Universal and BLDC motors that have been salvaged from washing machines and instead of getting basic scrap value for them I was looking to see if they could be used for other projects, unfortunately it all seems a lot more complicated than what I was expecting.
