Treadmill Motor Control Answered
I have a Horizon T101-04 treadmill that has a control problem. The motor is definitely good. I suspect that the motor control board is good, and the control panel board is bad. The control will not reset or go into diagnostic mode. I want to replace either the control panel board or the entire control system. The motor is 90V DC. For amperage, the motor label says "19A S6 25%" which has no meaning that I understand, other than perhaps that the maximum amperage is 19. The label says "APMS" rather than "AMPS", and I wonder if the "S6" is supposed to be "SC" for "stall current." All of the characters on the label are very legible. To replace the entire set of controls, I can use an industrial DC motor control, but how much horsepower does the control actually need to be able to provide? I don't think that the one on the treadmill actually provides 19A, and is probably close to 1 HP or so in its capability. To replace the control panel with something else and keep the existing motor control, what do I need? Do I need some type of complex driver circuit? Does it need feed back from tach sensor to do a good job of keeping the speed steady? If it will work well, I want a simple control set up like a KB Electronics KBMD-240D to which I will add a safety cut-off switch with a lanyard.
