Definitions
- the present invention relates to a reluctance motor with a stator and a rotor
- the stator is made of a ferromagnetic, but not permanent magnetic material and radially directed to the rotor stator teeth,
- stator permanent magnets emanating from de ⁇ nen permanent magnetic fields.
- Another way to build a three-phase motor, be ⁇ is to use a conventional three-phase winding in the stator, in addition to introduce permanent magnets in the air gap between the stator and rotor and form the rotor as a reluctance.
- a motor is described for example in DE 197 43 380 Cl.
- the magnets must be relatively thick to a strong force or mediating power step-permanent magnet ⁇ to generate field.
- the requirement of the large thickness runs counter to the desire to choose the effective magnetic air gap between the stator and rotor as small as possible.
- the object of the present invention is to modify the known reluctance motor in such a way that, in spite of maintaining the permanent magnets, a small effective magnetic air gap can be realized.
- the object is achieved in a reluctance motor of the above type mentioned ge ⁇ achieved in - that the permanent magnets are arranged tangentially ⁇ dernuten in the STAs
- the stator teeth have the rotor in the radial direction of a tooth spacing, the permanent magnets a magnetic distance. Characterized in that the magnetic distance at least as large as the tooth pitch, the effective magnetic air gap mi ⁇ can be nimiert.
- FIG. 1 shows a section through a reluctance motor and FIG. 2 shows an inventive detail of FIG. 1.
- a reluctance motor has a housing 1 in which a stator 2 is arranged.
- the housing 1 consists in ⁇ example of steel.
- the stator 2 consists of a ferromagnetic but not permanent magnetic material. For example, it can be constructed of iron sheets.
- the reluctance motor has a rotor 3, on which a rotor 4 is arranged.
- the rotor 3 is mounted in the housing 1 such that the rotor 3 and with it the rotor 4 is rotatable about a rotation axis 5.
- the stand 2 on the stator teeth 6, the radi ⁇ al, are directed so towards the axis of rotation 5 and from the axis of rotation 5 off on the rotor. 4
- Each two tangentially adjacent stator teeth 6 form between each a St Sut 7.
- In the stator slots 7 each have a part of a stator winding 8 is arranged.
- the stator teeth 6 have a tooth spacing a in the radial direction from the rotor 4. This tooth spacing a corresponds to the mechanically present and - in contrast to the known reluctance motor - at the same time also the effective magnetic air gap 9 of the reluctance motor.
- stator winding 8 in the radial direction of the rotor 4 to a winding distance b which is greater than the tooth spacing a.
- the stator winding 8 thus does not fill the stator slots 7. Therefore, it is possible to dernuten 7 permanent magnets 10 use, of which - trivially - go out permanent magnetic fields. Due to the insertion of the permanent magnets 10 in the stator grooves 7 thus the permanent magnets 10 are arranged on the stator 2. Due to this fact, they are furthermore arranged tangentially, ie in the circumferential direction around the axis of rotation 5, in the region of the stator slots 7.
- the permanent magnets 10 are magnetized in the same direction in the radial direction. This is indicated in FIG. 2 by arrows 11, which, viewed in the radial direction, are all the same direction, e.g. all radially outward.
- flux guide elements 12 are associated with the permanent magnets 10.
- the permanent magnetic fields are deflected into the stator teeth 6.
- the deflection is the art ⁇ that the permanent magnetic fields in the stator teeth 6 are directed in the opposite direction to the permanent fields in the region of the stator slots. 7 This is illustrated in FIG. 2 for one of the permanent magnets 10 by drawing in corresponding magnetic field lines 13.
- the flux guide elements 12 are made of a ferromagnetic, non-permanent magnetic material.
- the material may be the same as that of the stand 2.
- the permanent magnets 10 have in the radial direction of the rotor 4 on a magnet distance c.
- the magnet spacing c is preferably ⁇ at least as large as the tooth spacing a.
- the effective magnetic air gap By means of the reluctance motor according to the invention, it is thus possible for the effective magnetic air gap to be as small as the air gap 9 actually existing mechanically. This reduction in distance compensates or overcompensates for the reduction in the magnetic flux resulting from the fact that the permanent magnets 10 are in the tangential direction. see are spaced from each other. Furthermore, compared to the reluctance motor of the prior art, only half of the magnetic material is needed. In addition, the mounting of the permanent magnets 10 on the stator 2 and the entire Ferti ⁇ supply of the stand 2 simplified. In particular, the air gap can ⁇ 9 characterized in that the magnetic distance c is at least as large as the distance a tooth is to be made more accurately.
