AI Technical Summary

Technical Problem

Existing alternators are typically driven by the engine's crankshaft, limiting their operation to engine speed and efficiency, especially in applications requiring independent power sources or variable speed operation.

Method used

A separate DC motor is used to rotate an alternating current generator, allowing independent power source operation and variable speed control.

Benefits of technology

Enables independent power source operation and variable speed control of the alternator, enhancing its flexibility and efficiency beyond engine constraints.

Abstract

To provide a device that converts DC to AC and changes speed by transforming.SOLUTION: An AC compact motor is used to convert DC power to AC power. A commutator on the DC side, which is directly connected to a power source, has vertical grooves, but has also on the AC side vertical grooves. The commutator on the front side rotates a half turn, a coil rotates a half turn, and a commutator on the other side also rotates a half turn. This is three and a half time turns, the DC reverses every half turn, and finally, it becomes the AC.SELECTED DRAWING: Figure 1

Description

DETAILED DESCRIPTION OF THE PRESENTINg An AC generator is rotated by a separate motor. It is easier to understand if you think of an AC generator as being powered by another source of power, such as hydraulic power (a water turbine). In this case, it is thought that hydraulic power will be replaced by another motor. Even if there is only one battery, there are two pairs of cords (+) and (-). [Brief description of the drawings] [Figure 1] A DC motor, which is a separate power source, rotates an AC generator. Each time the coil reverses direction, the current smoothly changes direction, creating AC.

Claims

[Claim 1] A device that converts direct current into alternating current (inverter). A small DC motor is used to convert DC electricity into AC.
