SU117355A2 - Pulse generator - Google Patents

Description

BASIC Auth. St. a pulsed synchronous generator is described, which allows to obtain a series of unipolar and alternating pulses with small intervals of time between them.

The proposed generator is a further development of the generator by auto. No. 105147 and provides a reduction to zero residual voltage between the pulses.

This is achieved by the fact that on the shaft of the main rotor there is an additional rotor rotated by half a tooth division relative to the main one. The winding of this rotor is connected in series with the winding of the main rotor so that, in the intervals between pulses, an emf is induced in it, is equal in magnitude and opposite in direction of the emf. windings of the main rotor FIG. 1 of the drawing is a schematic diagram of the proposed generator; in fig. 2 is a circuit for turning on its windings.

In the generator, the additional shaft 3 is rotated to the shaft / main rotor 2, which is rotated relative to the main one by half of the tooth division. The winding 4 of the additional rotor is connected in series with the winding 5 of the main rotor so that in the intervals between pulses it induces an emf, equal in magnitude and opposite in the direction of the ed-c. windings of the main rotor. As a result, the residual voltage between the pulses decreases to zero.

An additional rotor can be placed both in the bore of the main stator 6 and in the bore of a separate stator 7. This stator can have the same or a different system of teeth as the stator 6 and the same number of poles shifted or not shifted around the circumference relative to the main stator . It can be covered by the same winding of the field as the main stator 6 with a counter or coordinated no. 117355

The windings of the main and additional rotors of the Stators 6 and 7, which are occupied by the excitation windings, can be wider than the adjacent adjacent slots that are not filled with a winding, and their divisions can be multiples of the division of the adjacent grooves.

On the stator of the generator against the main rotor 2 can be located clearly expressed poles 8 (Fig. 2), equipped with pole shoes with wide grooves, and against an additional rotor 3 - the same number of explicit poles with grooves or without grooves on the pole shoes and with uniform or uneven air gap between these poles and the rotor. On the main and additional rotors there can be several windings 5 and 4 connected in pairs (main with additional) and brought to one or several switches, from which unipolar pulses are removed. The machine can also be made with an excitation system on the rotor and with the main windings on the stator.

Subject invention

1. Pulse generator auth. St. No. 105147, characterized in that, in order to reduce residual voltage to zero between pulses, an additional rotor is rotated on the main rotor shaft, rotated halfway across the main, and the winding of this rotor is in series with the winding of the main rotor so that so that in the intervals between pulses in it induced emf, equal in magnitude and opposite in direction of the emf windings of the main rotor2. The generator according to claim 1, is different from that the additional rotor is placed in the bore of the stator of the main rotor.

3. A generator according to Claim 1, characterized in that the additional rotor is placed in the bore of a separate stator.
