I've built this 220v DC motor controller. I use a 2x110v - 2x15v transformer to power up the stator.
The transformer is a Myrra 45064 with the primary windings connected as follows: pins 1 and 9 connected to the mains, pins 4 and 6 in short.
On the secondary windings, i've connected pin 12 and 19 to a rectifier, and 14 and 17 in short.
When I plug it in at 220v AC, the transformer heats up very fast and outputs ~12V out of the expected 30V. Didn't keep it powered more then 6 seconds.
I thought that this pin configuration should connect the 2 halves of the transformer in series and output 15+15V.
Am I connecting them wrong, or there could be another cause for the high current through the transformer?
P.S.: The schematic on github shows a 3 port primary winding, however, the board is built with the connections done as explained above.
