Controlling Washing Machine Motor with an Arduino

Hi All

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

1 - TX02
2 - RX02
3 PRG_CLK
4 PRG_Data
5 Reset
6 GND
7 +3.3v
8 SCK
9 SDI
10 SDO
11 SDA
12 SCL

My will continue researching but if anyone has already done this, then no point reinventing the wheel.

Cheers

DJ

A very few similar works can be found featuring TDA1085. But could not find anything using the 256mc206 IC.

Hi

Thanks for the post, unfortunately the TDA1085 is used to control a Universal Brushed Motor, I dont think it would work with a 3 phase brushless motor.
