Magnetic circuits in rotation systems for generating electric and mechanical power such as machines in electric cars and ships. This rotation system is composed of three parts. One is a revolving field magnet (22) fixed at the axis (21). The second part is armatures with M type of magnetic circuits for generating the mechanical power. The third part is armatures with inverse Y type of electromagnets for generating the electric power that generates the electromotive force by receiving the induced magnetic flux from the revolving field magnet (22) and the armatures for generating the mechanical power. The M type magnetic circuits and the inverse Y type of electromagnets are separated by air gaps. With this, we have an efficient motor/generator since it can reduce the external power consumption since a part of the mechanical power is recycled by a switched electrical damping effect. |
