Y-Rag Posted June 19, 2012 Report Share Posted June 19, 2012 Hi,I'm new to electronics and have some questions regarding a project I am try to make.I want to turn a plastic corrugate display board using a Sankyo SHE9L motor. I have the frame and all made now I need the electronics. I think I should use a potentiometer to control the speed. If I use a 9V battery what size resistor should I use? Any other components needed? Also how should this be wired?Thanks for support anyone can offer. Quote Link to comment Share on other sites More sharing options...
audioguru Posted June 21, 2012 Report Share Posted June 21, 2012 I can't find a datasheet for the motor so I don't know its maximum current.The current will probably be too high for a potentiometer )it will burn up) and also too high for an ordinary little 9V battery (it might last for only a few minutes).An electric motor needs a high current to begin running. A resistor in series reduces the current then it might not start running.Usually a potentiometer controls a Pulse-Width-Modulation circuit for motor speed control. Then the motor can start running when the speed is set low.A transistor or darlington transistor can also have its input voltage adjusted with a potentiometr so its output can control the speed of the motor but then the motor might not start running if the speed is set low.
