Hi,
I need some advice with a problem I experiencing on a project I am working on.
The project consists of a 600W AC to DC converter 230V TO 24V 25-30A power switch transformer, a 10-50V 40A DC Motor Speed control PWM HHO RC controller 12V 24V, and a 350W 24 volt D.C motor, rated current 18.7A.
There is a pulley on the shaft of the motor that can be connected to another pulley situated on a drive shaft, with a drive belt, on this shaft is also a fly wheel, and a large pulley, which is not attached to anything at the moment.
The speed controller has developed a fault where the current flows through the circuitry by passing the on and off speed control switch, so that when you turn the power on, the motor starts spinning
Before the problem had accrued I had done tests runs with out a drive belt being attached between the two pulleys. Varying the speed over a five minute test run, and there were know problem.
Next I connected the drive belt between the two pulleys, started spinning the flywheel by hand, (so that the motor did not have its dead weight to contend with when it started spinning) then turned the speed controller on, and set it at a quarter of a turn. Ran it for five minutes, know problems.
Did exactly the same again, but this time I set the speed controller to half a turn, it ran for 4 minutes before the motor lost power, and everything started slowing down, then stopped.
I tested the AC-DC converter that works O.K, I tested the motor, and that works O.K
I did wonder whether the flywheel momentum could have build up, so that it ended up spinning faster, than the speed the controller was set at. So that the electric motor was forced to spin faster, with out the increase of power to do this. But I am just guessing.
Any suggestion on what might have caused the damaging to the speed controller, would be greatly appreciated.
