Description

[0001] Synchronous electric motor

[0002] AREA OF TECHNOLOGY

[0003] The invention relates to the field of electrical engineering, namely to synchronous electric motors, which can be used as motors in industry and everyday life.

[0004] LEVEL OF TECHNOLOGY

[0005] An asynchronous machine is known, disclosed in RU 2349015 C2, published 10.03.2009. The asynchronous machine contains two stators and a common rotor, which rotates freely relative to the shaft and has simultaneously two separate short-circuited windings for each stator and one short-circuited winding common to both stators, and one of the stators is located stationary on the shaft and rotates together with the shaft.

[0006] The disadvantage of the technical solution disclosed above is the low engine power due to the bulky engine design.

[0007] Furthermore, a two-transformer electric motor is known from the prior art, disclosed in RU 2086068 C1, published July 27, 1997, prototype. The two-transformer electric motor comprises two magnetic cores with windings and poles on the stator, and a rotor with a winding of separate closed turns. In this case, the two magnetic cores with windings and poles on the stator are closed by a single magnetic core of the rotor with a winding, the windings of the poles on the first and second magnetic cores of the stator are fed with alternating currents, shifted in phase by 90°, the second magnetic core with windings and poles on the stator is located at an angle relative to the first magnetic core on the stator with windings and poles.

[0008] The disadvantage of the technical solution disclosed above is the low engine power due to the bulky engine design.

[0009] DISCLOSURE OF THE INVENTION

[0010] The objective of the claimed invention is to develop an electric motor with a high electromagnetic torque value, ensuring high electric motor power.

[0011] The technical result of the invention is to increase the power of an electric motor per unit volume.

[0012] The specified technical result is achieved due to the fact that the synchronous electric motor contains a housing in which two stators are installed with an electric winding in the form of a plurality of stator coils located around a circle, and a common rotor, at the ends of the shaft of which two separate electric windings are located for each stator in the form of a plurality of rotor coils located around a circle, wherein the electric windings of the rotor are connected to each other via a phase correction circuit, and the electric windings of the stators are connected to each other via a power controller.

[0018] IMPLEMENTATION OF THE INVENTION

[0019] A synchronous electric motor comprises a housing in which two stators with electric windings in the form of a plurality of stator coils (1) arranged circumferentially are installed, and a common rotor, at the ends of the shaft (3) of which two separate electric windings for each stator are located in the form of a plurality of rotor coils (2) arranged circumferentially. Thus, at each end of the rotor shaft (3), rotor coils (3) are arranged circumferentially. The rotor coils (3) located on the right side of the rotor and the rotor coils (3) located on the left side of the rotor act as electromagnets. The rotor electric windings are interconnected via a phase correction circuit (matching circuit) (4), and the stator electric windings are interconnected via a power controller.

[0020] The claimed electric motor operates as follows. When power is applied to the electric motor, the power controller supplies current to the stator coils (1), located and aligned with the rotor coils (2) on the left side of the rotor. As a result, the stator, on the left side of the rotor, induces an EMF in the rotor coils (2) on the left side due to electromagnetic induction. Current then flows from the rotor coils (2) on the left side of the rotor into the phase correction circuit (4), located between the two rotor sections, where it is increased to the required value and fed to the rotor coils (2) on the right side. The rotor coils (2) on the right side are repelled by electromagnetic induction from the stator coils (1) located and aligned with the rotor coils (2) on the right side of the rotor. Next, the power controller supplies current to the stator coils (1), located and combined with the rotor coils (2) on its left side; the stator, due to electromagnetic induction, excites an EMF in the coils (2).Current from the rotor coils (2) on the right side then flows into the phase correction circuit (4), located between the two rotor halves, where it is increased to the required value and fed to the rotor coils (2) on the left side. This causes the rotor shaft (3) to rotate, transmitting power, for example, to the wheels of a car.

[0021] The proposed electric motor design allows for increased induced EMF in the rotor by using a larger parallel winding area. Consequently, the rotor has a higher external excitation power comparable to permanent magnets, which increases torque, i.e., increases the electric motor power per unit volume. The use of a power controller allows for an increased number of electromagnetic coils in the stator, thereby increasing torque.

[0022] The invention has been disclosed above with reference to a specific embodiment. Other embodiments of the invention may be apparent to those skilled in the art without altering its essence as disclosed herein. Accordingly, the invention should be considered limited in scope only by the following claims.
