neiji1000 Posted July 14, 2007 Report Share Posted July 14, 2007 Currently I am being asked to maintain the speed of a 12V dc train when it run round a curve path. how am I going to implement such a voltage controller so as to maintain the speed? thanks in advance.

marke Posted July 15, 2007 Report Share Posted July 15, 2007 Hello neiji1000 If you use a switching voltage controller rather than a linear voltage controller, you can monitor the voltage generated by the motor during the OFF period. This voltage is proportional to the speed of the motor and can be used to regulate the speed. This is commonly done in industrial DC motor controllers, and while not as accurate as a tacho feeback system, it is perfectly adequate for most installations.
