Not sure if that's what ultimately caused the tiny shaft to break but I suppose that could be the reason. I just assumed I had to invert the orientation.Īnother issue I've had is the quick starting of the DC motor it slams on and the KBLC-19PM doesn't have a ACCEL pot to adjust it down. The label on my latest motor doesn't differentiate between CCW or CW. I just can't see strapping a 56 lb motor up there. I've got a 2.25 hp continuous duty DC that's much much smaller than a 1.5 hp AC motor. The problem with that is since this is for the X2, the motor size would be pretty overwhelming. I'm thinking about abandoning the whole DC motor setup and going with a VFD and AC motor. I didn't do this to begin with because I'd read that the brushes need to be offset slightly on the commutator in order to be bi-directional motors. Clean break both times.įrom what you've stated I could have used the larger end all along by just swapping the wires. The second treadmill's shaft broke yesterday at the same location as the first, right at the shoulder where the fan shaft (7mm) steps up to 10mm. So I had to use the smaller end of the treadmill where the fan normally is located. That was recommended to me somewhere along the swapping out process some years back. Mounted my treadmill motor upside down to get the rotational direction needed.
