The invention relates to electric machines, in particular to inductor motors, and can be used in high-torque si.vivyh electric drives. The purpose of the invention is to increase the specific moment per unit mass, efficiency and engine power ratio.

Fig I shows the engine structure; in fig. 2 is a schematic of the connection of the motor windings.

The synchronous inductor motor consists of a cTiiTopa with clearly expressed 2 b i poles. on which the three-phase main winding 14 is formed, formed by C01 redc) coils. 15 - 26, and an additional excitation winding 27, formed by successively connected concentrated coils 28 - 39. Each fa :: a t of the phase winding contains two narall -. branches 40-41, 42-43, 44-45. In the first phase of the 40 phase, Kagushkam 1 and 21 are formed. The second branch 41 of the same phase is formed by coils 18 and 24, the first branch 42 of the second phase is formed by the coils 19, 25, the torus branch 43 of this phase is formed by a pin 16 and 21, the third branch 44 The phases are formed by KaTyinkami 17 and 23, the second 45 of this phase is formed by coils 20 and 26. The first branches 40. 42, 44 of each phase are connected to the positive electrodes of the valves 46, the second branches 41, 43, 45 of each phase - to negative e. - | sktr (),; al. Within each branch of the coil -26 are connected afterwards to the beginnings to the ventilator t 46. The ends of all the first 40 44 and all the second 41-45 netias are connected into two stars. An additional excitation winding 27 is turned on between 1M11MI points of stars, in which, as can be seen from FIG. 2, located on neighboring zeroes 2--1 3, for example. .L and 32-, included counter. In this case, all coils 28 -39 with even numbers are connected to the bullet point of the first star by their beginnings, and to the bullet point of the star by ends, so that the coils of the main three-phase winding 14 and additional polarity of the excitation winding 27 are spread. Young on one and the same position 2 13, included according to. On the inner surface of the poles 2 13., facing the air gap; B1.1 are filled with zhbtsy 47. The rotor 48 is also made gear with teeth 49.

The device works as follows. When the 3-phase winding 14 is turned on to an alternating voltage network, TQKFL creates a rotating magnetic field through it. FIG. The figure shows an approximate diagram of the MDS (floor) of a three-phase winding for the point in time when the maximum positive current flows through 14-20 coils. Kai can be seen from the connection diagram of the three-phase winding (Fig. 2), at different times only positive coils flow through all the coils with odd numbers 15, 17, etc., and across all coils with even numbers 16, 18, etc. negative currents. Accordingly, the rotor 68 always strives to assume such a position that in the region of the maximum field there is a minimum magnetic resistance of the air gap, i.e., to ensure the coincidence of the teeth 47 and 49 of the stator 1 and the rotor 48.

The proposed electric motor has an increased specific moment per unit mass and increased efficiency and power factor compared to the known one by increasing the constant component zero by turning on the auxiliary excitation winding.
