LINEAR ELECTRIC MOTOR Russian patent published in 2009 - IPC H02K41/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, particularly to linear alternating current motors and can be used in translational motion electromechanical systems. The electric motor contains an imbricated stator core 2, with a polyphase winding 1 on it, and attached to the housing 3. A flange 4 is joined to the housing. The rotor has three permanent magnets 5, located between two magnetic cores 8. Two magnetic cores 6 have claw-teeth 7, facing the inner cylindrical surface of the imbricated stator core 2. Non magnetic bushings 10 are attached to lateral magnetic cores and rotate in bearings 9. A ferromagnetic liner 11 can execute translational motion along the axis of rotation of the rotor. All permanent magnets 5 are magnetised in the axial direction head-on. Magnetic cores 6, 8 and ferromagnetic liner 11 have threading with the same pitch on the inner and outer cylindrical surfaces, respectively.

EFFECT: improved weight and size characteristics.
