I have a problem with a project, and needs some advice.
A brief description of the component involved. There is a 230 volt AC to 24 volt DC converter, which connects to a 24 volt speed controller, which is connects to a 24 volt D.C Motor.
Did a test run of the above set up, everything worked O.K
Then attached a belt to a pulley on the motor, to a pulley on a drive shaft, on this shaft is a flywheel.
I spun the flywheel (so that the motor did not have its dead weight to contend with when it started spinning) Then did a test run, at a quarter speed for five minutes, everything worked O.K
But when I did the next test run, at half speed, (spinning the flywheel as I did before), everything worked O.K for four minutes. Then everything started to slow down and stopped, (the flywheel on this test was really moving quite fast). The reason why I mention this, is because, I tested the motor, and the converter and they working O.K
The on and off speed control switch has developed a fault, it seem. I did a separate test of the speed controller, and the motor using a 24volt battery set up. When I turned the power on, with the speed controller switch in the off position, the power bye passes the switch, because the motor started spinning.
I was wonder whether the flywheel momentum could have build up, so that it ended up spinning faster than the speed controller, was set at, for the electric motor to rotate at. So that the electric motor was forced to spin faster, than it should, relating to the setting on the speed controller, this is hypothesising on my part.
Any suggestion on what might have caused the damaging to the speed controller, would be greatly appreciated, and also how to stop this happening.
