    1515776 Alternators J H JARRET and J M B JARRET 8 June 1976 [9 June 1975] 23565/76 Heading H2A An alternator includes a coil 1 which is surrounded by a yoke 2 which co-operates magnetically with a cyclically moving magnetic body 3, the ends of the coil being connected to terminals of a constant voltage source 5 via controlled valves 6a, 6b, and each coil end having a further connection to the terminal of opposite polarity via a monodirectional current link 7a or 7b. In the position of Fig. la, valves 6a and 6b are closed for a short duration, and a current pulse flows through coil 1 to magnetize the magnetic circuit. Valves 6a, 6b are then opened, Fig. lb, and the reduction in flux in the circuit as part 3 moves to the right causes a voltage to be induced, current flowing in the links 7a, 7b. On reaching the end of its travel to the right, (Fig. 1c, not shown) the current is abruptly interrupted; and no current flows during the return stroke (Fig. 1d, not shown). Valves 6a, 6b may be thyristors, and links 7a, 7b may be diodes. Rotary alternators are also envisaged.

    专利说明:

    The invention relates to electrical engineering and can be used in the design and operation of reciprocating generators, mainly when operating such generators with noiseless heat engines, in which the rotor and stator of the generator can be structurally combined with the piston and cylinder of one heat engine. . A generator of reciprocating motion, the stator of which is made of laminated gel, is known in the form of a cylinder, in the grooves of which the root winding is located, and an excitation winding is placed on the rotor connected to a direct current source. The disadvantages of this generator are connection of the movable rotor with the power source, as well as the presence of: excitation winding on the rotor, which reduces the reliability of the generator and complicates its design. The closest technical solution to the invention is a reciprocating motion generator comprising a fixed magnetic core with a single-phase core disposed on it, a non-winding rotor, a winding power supply and a pulsed excitation current regulator 121. A well-known generator characterizes the stator system, since the winding is located on the same stator magnetic core and when the rotor moves in it, a variable EMF is induced, which enters the constant-voltage power source eye and can cause k it fails. To eliminate this phenomenon. The winding is divided into separate parts and placed on the magnetic core so that the algebraic sum of the EMF of all parts of the winding is zero. The need for such placement of the winding complicates the design of the generator and increases its weight and size parameters. The purpose of the invention is to simplify the generator and reduce its mass and size NBk parameters. The goal is achieved by the fact that in the generator of reciprocating motion, the magnetic generator of the stator of the generator is U-shaped with the main winding located in the inner cavity of the magnetic circuit, the rotor position sensors are additionally located on the stator, and the exciter current regulator is in the form of single-phase two-wave half-wave bridge's bridge, two opposite sides of which are formed by controllable keys, and the other two are diodes, and to the DC output of the rectifier the bridges are connected to the terminals of the core winding of the generator, and the output of the power source of the windings is connected to the AC input of the rectifying bridge, and the outputs of the sensors are connected to the control circuits of the controlled keys. Additionally, a second U-shaped stator magnetic core can be inserted, located coaxially with the first magnetic core, while the core winding is also located in the inner cavity of the second magnetic core, and the total magnetic core length is equal to the full length of the rotor movement. In addition, a second pulsed regulator of the excitation current and a second set of rotor position sensors may be additionally introduced, while the second root winding is connected to the output of the direct current of its pulsed regulator of the excitation current. FIG. Figures 1–4 show the generator design diagrams with different rotor positions during operation. FIG. 1-4 shows the states of the keys of the pulse regulator of the excitation current depending on the position of the rotor and the circuit diagrams of the elements of the pulse regulator of the excitation current with the main winding, magnetically sensitive sensors and the winding power supply are given, with the keys being controlled on the thyristors, FIG. . 5 is a structural diagram of the generator when performing its magnetic circuit of two U-shaped parts. FIG. 5 pre: connection of the generator cores, with two pulse retractors of the excitation current. The anchor winding 1 is located in the inner cavity of the U-shaped magnetic circuit of the stator 2. The rotor-free rotor 3 has the ability to linear re-measure inside the stator 2, thereby changing the size of the air gap 4. The power supply 5 of the winding is connected to the winding 1 through a pulsed regulator of the field current made in the form of a single-phase full-wave rectifying bridge, two opposite arms of which are made on controlled keys 6 and 7, for example, thyristors, and the other two on diodes 8 and 9. Sensors 10 are position of mouth The rails are connected by their outputs to the thyristor control circuits 6 and 7. The magnetic circuit of the generator stator 2 may consist of two U-shaped parts (Fig. 5), in the inner cavity of each of which there are main windings, each of which is connected to its inputs pulse regulators formed by diodes 8 and 9, respectively, and tyrants 6 and 7. The reciprocating motion generator operates as follows. At the position of the rotor 3 shown in FIG. 1, the gap 4 has a minimum value and the rotor position sensors 10 give a signal to turn on the thyristors 6 and 7, which are connected between the power source 5 and the winding 1 core, thereby creating an excitation flow in the magnetic circuit 2 of the stator. When the rotor 3 is moved to the intermediate position shown in FIG. 2, the thyristors 6 and 7 are locked. Moving the rotor 3 leads to an increase in the air gap 4, which causes a decrease in the magnetic flux of the magnetic circuit of the stator 2 and the induction of the EMF in the core winding 1. The resulting EMF has a value greater than the voltage of the power source 5, which leads to the opening of the diodes 8 and 9 and current flowing through the source 5, during which, for example, the battery is charged or the load is energized when it is switched on parallel to the source 5. When the other extreme position (Fig. 3) is reached, the rotor stops, EMF in winding 1 disappears, diodes 8 and 9 locked and, since the thyristors 6 and 7 are also locked, the power supply 5 is disconnected from the core winding 1. When the rotor 3 returns (Fig. 4), the closed state of the valves is maintained until the rotor 3 is in the position shown in fig. 1, after which the cycle is repeated. The duration of the excitation pulse is approximately 1-10% of the total duration of movement of the rotor 3. A generator with two main windings works in a similar way. The difference is the use of the return run of the rotor 3 to induce an emf in the core winding 1, for which such a run of the rotor 3 is straightforward, which improves the efficiency of the generator and improves the quality of the electrical energy supplied to the load.
