circuit for a synchronous steering motor without brush permanent magnets and variable speed powered directly from network inalternata.

摘要

the steering circuit of an engine without permanent magnets synchronous brushes with variable speed, and bidirectional.powered directly from the ac network and having at least four coils, two of which main wrapped at 90 degrees electrical and two additional.the circuit is formed by at least one sensor tachimetrico and a detection device of the position of a rotor which is connected to a control circuit that is connected to devices of gdpotaggio in alternating current (triac) of windings.additional coils are wrapped in the opposite direction to the main windings on the same polar expansions of one of these windings statore main.
