Abstract: This invention concerns an improved turbo-electrical generator powered by the conversion of natural energy into mechanical energy in order to propel ferromagnetic blocks about an irregularly, non-circular shaped closed loop track, alternately entering and passing through a plurality of electromagnets positioned about the track. As these blocks enter and pass through these electromagnets, their magnetic flux is maximized and then minimized and this change is converted into useable A.C. voltage. Means are taught for the conversion of solar energy, wind energy and wave energy into the necessary mechanical energy to propel these blocks about the closed loop. An alternative embodiment employs a rotatable, ferromagnetic cross shaped device which is rotated about a center axis by the passage of the blocks about the track. As the device is rotated, its extremities enter and pass through the electromagnets positioned about the track.

Abstract: Control system for a motor having a shunt field winding is disclosed. In an electric vehicle, when an accelerator pedal is stepped on at the start, a field current is increased to increase the rotational speed of the motor in accordance with the stepped angle of the pedal. In the operating region where the rotational speed of the motor is not increased in accordance with the increase of the field current, an armature current is in turn increased and inversely the field current is decreased in order to further increase its rotational speed. Thus, an impact at the start can be reduced.
