Description

I The invention relates to electric machines and can be advantageously used to create electric pulse energy generators.

Electromachine amplifiers (EMU) with a transverse field are known and widely used, containing rotating measles with brushes along the transverse and longitudinal axis of the collector. In this case, the lio brushes of the transverse axis are closed, and along the longitudinal axis they are connected to the compensation winding, the winding of additional poles, and then connected to the load. On the stator there are windings of upslets and windings of additional clauses 6.pussovS11.

The disadvantage of these amplifiers is the presence of the collector and the rotation of the windings of the core. The amplifier's co-collector does not allow for a significant increase in speed due to the impairment of the switching, and therefore it is not possible to reduce the time constant. Switching phenomena also reduce the quality of the entire machine. The presence of the collector does not allow a significant increase in the voltage of the EMU and its power, since the energy is removed from the sliding contact. EMU

cannot be used as a shock power amplifier. .

The closest to the present invention is an electric machine pulse generator, containing an inductor, located on the rotor, located on the stator with measles, the terminals of which are connected to a load circuit, switching devices, which are rotated by the position of the rotor 2..

The disadvantage of this gadget is that it is impossible to adjust the parameters of the spin pulse.

The purpose of the invention is to improve the functionality of the generator. and areas of application.

30 with switching devices. The generator has a large degree of regulation due to control windings and therefore can be used both for small machines and for large ones. Fig. 1 shows a circuit diagram of an electric machine amplifier pulses in Fig. 2 a diagram of the connection of the rotor windings. The generator contains a stator, on which is located a distributed root winding 1, made with 2-3, 4-5, 6-7 waters along the transverse axis 8-9. The taps 2-3 are made along the spring axis, and the rest are evenly displaced relative to the axis in the opposite direction of the rotor. The ends of the taps are connected to switching devices 10, 11 and 12. In general, taps can be made to both sides of the transverse axis. Along the longitudinal axis 13-14, the same branches are made 15-16. A compensating winding 17 is connected to tap 1 via brushes 18 to 19 and rotor rings 20 and 21. In parallel with the brushes, a control resistor 22 is connected, through which the degree of compensation of the core is adjusted. The taps 23 and 16 are connected to the load 24 via the switching device 25. The switching devices along the long and lateral axes are turned on and off as a function of the rotor position from the control sensor 26. Depending on the purpose of the ECU, the rotor can be made not landed or landed. At higher speeds, the rotor is made not clearly polar. On the rotor there is a control winding kit 27 and a compensation winding 17. The control winding kit consists of several windings (three windings are indicated in Figure 2: 28, 29, 30). All windings with one pole can be combined and connected to one common current-carrying ring 3, the remaining ends of the windings are connected to rings 32, 33, 34 and 20 (Fig. 2). Winding 28 is the driver that determines the operation of the amplifier. The winding 29 has the opposite direction of the coils compared to the winding 28 and is connected at one end to the latter. The winding 29 through the rings 32 and 33 and the jaws is connected to the switching device 35, which short-circuits it and thus turns it into a damper. winding. The current to the winding 28 is supplied to the terminals 36 and 37, and the surrounding windings of the ECU serve to form the necessary characteristics. They can serve as load feedbacks or other algorithms. The applied connection of windings with rings reduces the number of rings, and also contributes to the unloading of brushes from currents. The rotor is driven by a special motor. A DC voltage is applied to the driver winding (ends 36-37). The switching device 35 is connected, the winding 29 is shunted. The driver winding 28 creates a magnetic field that induces an emf in the winding of the core, the polarity of which is located. perpendicular to the excitation winding. and moves around the circumference of the winding at the speed of SU, where f is the frequency; p is the number of pairs of poles. There is no current in the winding of the core (when restoring) in the idle mode. When the long axis of the rotor crosses the transverse axis of the stator, the commutator apparatus 10 is turned on, and due to the occurrence and increasing reaction of the core, the stator axis 13-14 rapidly increases. When creating the longitudinal axes of the stator and the rotor, the EMF between points 15-16 reaches a maximum, and therefore at this moment the switching device 25 switches on and gives an impulse of electrical energy to the load 24. At the same time, or a little later, the switching device 35 is triggered. the excitation Toir decreases as the winding 29 is connected. In addition, the winding 29 contributes to demagnetization, which in turn increases the pulse of the energy produced. By adjusting the turn-on time of the coil 29 as well as its parameters, it is possible to change the nature of the energy pulse curve, forming it according to the required nature for the load 24. When the longitudinal axis of the rotor is located along the stator axis 8-9, the switching device 10 is turned off, and then 25 and turned on Comm. A device 35. In the ECU, the idle mode is restored. . After half a turn, the process is repeated. In this case, the load receives unipolar energy pulses. If necessary, pulses of energy can be applied to the load at every half turn of the rotor or other intervals. In this case, the load receives bipolar pulses of energy. Thus, the generator can supply the load both unipolar and differently with current. The energization and deactivation intervals of the energy pulses are controlled by the setting of the control sensor 26. . To simplify control, the switching apparatus 10 may be switched on permanently, but in this case the efficiency of the installation is reduced. When connected instead of the switching device 10, the devices 11 and 12 change the ratio of the action of the core reaction along the longitudinal and transverse axes, thereby changing the magnitude of the electrical energy of the consumer. Winding 29 plays the role of a damper along the longitudinal axis of the rotor when it is closed, whip. At the same time, it facilitates the growth of energy impulse upon opening, as well as extinguishing the magnetic field, and then restoring it upon disconnection. The ratio of the parameters of the windings 28 and 29 is taken specifically for each machine. The device provides for work with overcompensation due to the absence of a collector, which leads to an increase in the EMF of the output, as a result of which the impulse of electric power increases. Additional poles in the amplifier are missing.
