ABSTRACT:
This book as so many others, illustrate the combination of electronics and
electricity. It exists, currently several methods to make continuous current vary the
speed of a motor, and what one adopted here is one of it.
One can have a straightened tension varied comfortably while using an
electronic order circuit. Indeed the variation of the speed through the intermediary
of the variation of tension of induced seems more advantageous that that is
technically or economically. It doesn't exclude the variation of the speed all the
same by flux or the one potentiometer. In our case, the motor to current
continuous permanent magnets don't allow us to make vary the flux.
The theoretical studies elaborated in the first left of this memory concerning
the relative equations to the motor to continuous current. The last part rather puts
in evidence the convenient results.
