Direct current motor speed controlling method for e.g. automobile, involves limiting electrical power, where power is moved into winding provided in region by FET that is operated at resistance region

摘要

The method involves alternatively designing and successively moving windings, by regions of a magnetic field so that one of the windings is provided at the same time in each region. The windings present in one of the regions are deactivated while interrupting supply of the windings with an electrical power. The electrical power is limited, where the power is moved into the winding provided in the other region by a FET (Q1) that is operated at a resistance region. An independent claim is also included for a circuit for controlling speed of a direct current motor.
