The invention relates to electrical engineering, in particular, to AC motors with built-in electromagnetic clutches, and can advantageously be used in automatic control systems.

The purpose of the invention is to reduce the weight and size parameters.

The drawing shows an electric motor with integrated clutch, general view.

The electric motor consists of a fixed housing 1, in which pa3iiemeubi stator 2 electric motors, in the case of KaTiTUKa 3 t-sleeve excitations with a fixed magnetic conductor and ball bearings 4 in which the output shaft 5 with the rotor 6 of the coupling is mounted.

The ball bearings 7 are equipped with a rotor consisting of two coaxially arranged cylindrical magnetic cores 8 and 9, which are rigidly interconnected and are simultaneously the leading part of the coupling.

The mutually facing surfaces of the magnetic cores 8 and 9 in the zone of one of the end parts of the rotor have protrusions-poles 10 and form a gear coupling inductor. In the gap between the poles 10 is located the rotor 6. a coupling made of a hysteresis alloy in the case of a hysteresis coupling or in the form of a massive glass made of a ferromagnetic material in the case of an industrial coupling. The magnetic cores 8 and 9, the rotor 6, the coil of the excitation 3 with a fixed magnet top, separated from the magnetic cores of the rotor by an air gap

11, form an electromagnetic coupling theme, with magnetic currents from the stator 2 of the motor and the coil 3. The coupling is closed. 5 sec through the outer magnetic conductor .9 in a mutually perpendicular direction.

When current is applied to the excitation winding 3 of the coupling, a coupling force between the leading part 8-9 and the rotor 6 arises, as a result of which the output shaft 5 begins to rotate at a frequency depending on the current in the winding. .

The design of the proposed motor with clutch is compact, simple and has less weight.
