Abstract

The invention relates to electrical engineering and can be used in automation systems. The goal is to increase efficiency and reliability. The linear electric motor contains a laminated magnetic core 1, a winding 2 core, a PMO 3, annular permanent magnets 4, ferromagnetic sleeves 5, bearing shields 6, bearings 7, magnetic circuit 8 of the rotor, nonmagnetic sleeve 9, cylindrical magnetic core 10, support 11, guide 12, a rotor 13 with kuvoobraznymi teeth 14, and on the inner surface of the sleeves 5 and on the outer surface of the magnetic cores 8 made annular thread with the same pitch, and on the outer surface of the magnetic core 10 and on the inner surfaces of the magnetic cores 8 on the screw thread with the same pitch. When power is applied to the winding 2, the core begins to rotate and, interacting with the magnetic core 10, moves the stator to one side or the other. Sleeve 5 with a cylindrical thread relieves bearings from axial force, which increases the efficiency and reliability of a linear electric motor. 1 il.

 Electron rotor contains magnetic magnetic conductors 1, 2 core winding, PMO 3, annular permanent magnets 4, ferromagnetic sleeves 5, shchshmipnikovgie shity 6, bearings 7, rotor magnetic conductors in v1-f.e of nuts 8, non-magnetic} 1 sleeve 9, cylindrical magnetic conductor 10, support II, guide 1 2.

Permanent (, 1e magnets 4 are magnetized radially with opposing

The magnetic nuts have the shape of a hollow cylinder with beak-shaped teeth 14 facing to the magnetic circuit 1 of the stator and the alternating forming alternating poles of the rotor. The sleeves 5, the magnetic rotor 8 and the cylindrical magnet 10 are separated by an air gap) m.

An annular thread with the same pitch is made on the inner surface of the sleeves 5 and on the outer surface of the magnetic rotor 8, on the outer surface of the magnetic circuit 10 and on the inner surface of the rotor 8 magnetic conductors there is a screw thread with (1 dip, pc (1st luai iiM,

When applied to the winding 2 core, a rotating field appears, and no first field, which carries along the jioTop. When the magnetonrove is rotated, an axial displacement of the screw thread of the rotor magnet 8 relative to the thread magnet wire 10 occurs and an axial force occurs, under the action of which the ring threads of the magnetic conductor 8 are displaced relative to the threads of the bushings 5. An axial force acts on the bushings 5, in this case the stagor will move the transducer1, and its position corresponds to the mi1P1muma of the magnetic resistance between the magnetic conductors of the rotor 8, the sleeves 5 and the magnetic conductor O.

The main part of the magnetic flux passes through the bushings 5 and rotor 8 power lines along the shortest path in the radial direction, due to which the sleeves 5 and nuts 8 moss are very thin, m (the inertia of the nuts B is small and they can rotate with great acceleration.

On bearings 7 axial force not. It acts as it is transmitted by the magnetic conductor 8 to the bushes 5 through a magnetic field, therefore mechanical losses in them are practically absent due to which the energy indices increase.
