SU34065A1 - Variable Speed DC Generator - Google Patents

Description

The present invention relates to themselves: already known generators of direct current with a variable number, revolutions, equipped with split poles. In the proposed similar generator, it is applied on the cortex, in addition to the collector field current, a short-circuited winding, with the aim of increasing the current in the generator circuit с; give a demagnetizing reaction field of the core.

In FIG. 1 depicts a schematic device of the proposed generator and FIG. A 2-way winding pattern for brushes.

The stator of the generator is equipped with N-NI and S-Si splitted in luxes (Fig. 1), of which part of the NI pole and the corresponding part bi are highly saturated and equipped with an excitation hitch HSHfig.C), adventured to main brush A and auxiliary brush 5, located between the parts and the split pole TV. On the generator core, except for the collector winding 7, a short-circuited winding is applied, and a slightly asy; The common parts of the NnS pole are winding A, adventitious to the main brush C and aux. Ogatelnaya-in. /

(337)

The winding K feeding from the brushes A and B creates magnetic fluxes, shown by solid lines, with a common flow in the direction of the arrow E, and the winding M creates a demagnetizing reaction field of the core closing through the weakly saturated parts of the poles, in the arrow I. an increase in the number of revolutions of the core, as a result of which, between the main brushes, it maintains a constant voltage, winding of M coils worn on the poles, and compensates for the response of the working winding when the load changes.

Prilmet invention.

A DC generator with a variable speed, equipped with split poles, characterized by the use on the cortex, except the collector winding, the short-circuited winding D intended for increasing the current in the generator circuit to create a demagnetizing reaction field of the core closed through weakly saturated parts of the L, S poles with the o6j coil excitement L, adventured to one main brush C and auxiliary brush B, which is located between the parts of mi-Lch and L / split pole

I ,,. .

., of which the first part of L / 1 and correspondingly, and to her part of Sj. are made strongly

saturated and equipped with an excitation winding L, adventitious to another main brush A and the same auxiliary brush B.%
