Hi, I've bought a treadmill 2nd hand. But after an hour of use the fuse blew in the house. Now every time I turn the treadmill on, everything lights up fine, but the second I turn on the belt the fuse blows. If I disconnect the motor, there's no problem but I can measure 280VDC (DK 240V in sockets) on the motor connectors and the motor are 160VDC. So I suspect that it blows the fuses because the motor tries to take off too fast. Normally it would start very slow and then you have to crank it up if you want it to run faster.
I suspect the either the IGBT or the Thyristor is shortened. But I'm not sure anyone know what it could be?
