Embodiment Construction

[0028] Such as figure 1 As shown, the stator system of the linear oscillating motor is composed of an annular disk-shaped permanent magnet 4 magnetized in the axial direction, and ring-shaped first pole pieces 5 and second pole pieces 6 are respectively provided on both ends thereof. The inner and outer diameters of the pole pieces 5 and 6 are equal to the inner and outer diameters of the magnet 4 .

[0029] The oscillating system is concentrically arranged and installed inside the stator system in a manner that can move along the axial direction. The oscillating system is composed of a ferrite core 1, on which a first excitation coil 2 and a second excitation coil 2 are wound. Energize coil 3. As long as the oscillating system is in its central position, the first coil 2 is located in the center of the first magnetic gap 7 and the second coil 3 is correspondingly located in the center of the second magnetic gap 8 . The movable supply wires for the coils 2, 3 need only be sl...

Abstract

The invention relates to an electrodynamic linear oscillating motor characterised by high power densities in the magnet gap, magnetic return of the oscillating system to the centre position and a comparatively low weight of the oscillating system. The linear oscillating motor comprises a stator system, which is provided with at least one magnet (4) and an oscillating system which is supported such that it is able to move in the magnetic field of the stator. The oscillating system comprises at least one core (1) made of a magnetically soft material, e.g. a ferrite, and at least one driving coil (2, 3). The oscillating system is designed such that, if at least one driving coil (2,3) is de-energised, it is returned to the centre position by way of a reluctance force acting on the oscillating system. The electrodynamic linear motor in accordance with the present invention essentially combines the advantages of the known MC and MM linear motors, enabling electrodynamic conversion rates of up to 99% to be achieved. The linear oscillating motor is particularly suited as a drive for refrigeration and air-conditioning systems with low power ratings, as well as for pump, injection and shock absorber systems in automobile engineering.

Description

technical field [0001] The invention relates to an electric linear oscillating motor, which has the characteristics of high force density in a magnetic gap, magnetic reset of the oscillating system to the central position, and light weight of the oscillating system. The electric conversion rate of the electric motor can reach 99%. The linear oscillating motor is particularly suitable as a drive in low-power refrigeration and air-conditioning systems as well as in pumping systems, fuel injection systems and damping systems in automotive engineering. Background technique [0002] Household low-power refrigeration equipment and air-conditioning equipment mainly use piston compressors. For reasons of economics, rotary compressors, such as scroll compressors, are only used in equipment with a drive power of several kilowatts. [0003] Piston compressors are driven by an electric motor, which typically produces rotary motion. A corresponding crank mechanism needs to be provided...
