catsfly Posted October 11, 2006 Report Share Posted October 11, 2006 hello, I have no idea if I'm in the right place but I need help....I have a DC motor, that powered a treadmill, I'm using it to power a device I had built. I needed to be able to plug it in, and I needed to be able to vary the speed so we kept it connected to the computer board from the treadmill. The problem is, the computer board is designed to 1. not allow the motor to get to full speed and 2. shut off if there is a problem. Because of this, my device is not working properly and I will have to disconnect it from the treadmill computer board.So....I still have this DC motor that I need to use, I would like to be able to 1. plug it into an outlet and 2. vary the speed of the motor.My main question is, is there a device that will convert this DC motor so that I can plug it in?

ante Posted October 12, 2006 Report Share Posted October 12, 2006 Hi catsfly,Welcome to our forum.You probably have to custom build a controller circuit for your motor. We need to know the motor data, the voltage from your outlet and perhaps a few things more to be able to help out. Quote Link to comment Share on other sites More sharing options...
aartak Posted October 15, 2006 Report Share Posted October 15, 2006 Check output voltage of your computer boardThen you can connect external DC power supply in series with in to increase sieed of motorTo connect it to AC simply use transformer with apropriate woltage and diode bridge Quote Link to comment Share on other sites More sharing options...
