Definitions
- the present invention relates to a polycentric electromagnetic motor and rotor radial magnetic flux framed by two stators with reduction of the detent torque which finds a particular but non-limiting application as a power steering motor in a motor vehicle.
- an electric motor is used in addition to the manual steering force exerted by the driver of the vehicle.
- Such an electromagnetic polycentric and magnetic flux motor comprises at least two stators flanking at least one rotor, an air gap, therefore at least one double gap, being defined between each of said at least two stators and said at least one rotor thus framed.
- the rotor carries at least one series of permanent magnets, while at least one series of winding elements is carried by each stator.
- each of the winding elements comprises a tooth carrying a coil, the tooth being framed on each of its sides by a notch, a good conductor wire being wound on the tooth to form the coil.
- the rotor which is secured to the output shaft of the motor is subjected to a torque resulting from the magnetic field, the magnetic flux created being a radial flow.
- a winding element comprises iron, the iron being able to be constituted by the winding support means or a central iron core for channeling the magnetic field passing through the winding element.
- the winding element may also have iron teeth on which a winding is wound respectively.
- CN201869064 discloses a polyentrefers motor with a double stator acting as a winding element surrounding a rotor acting as a permanent magnet element, these magnets being based on rare earths.
- the rotor is thus positioned between the two stators, a winding being integrated in an assembly slot of the support tooth of a stator winding which also comprises an iron core.
- the permanent magnets are embedded in a conductive ring to provide a multi-pole magnetic field for the air gaps on the left and right sides simultaneously.
- Each stator can drive the rotor in rotation and the two stators can work simultaneously or alternately.
- Such a dual stator motor and a single rare earth permanent magnet rotor provide increased output power and its efficiency is improved over a single gap motor.
- iron losses can be of two types.
- the first type concerns hysteresis losses due to the permanent magnetization of the magnetic path.
- the second type relates to eddy current losses produced by the rotating magnetic field. These losses lead to a heating of the entire engine or generator as well as to torque losses due to a lower intensity of current available for the operation of the engine, especially at high speeds of operation.
- Document DE-A-198 38 378 describes a radial flow motor comprising at least a double air gap comprising at least two stators flanking at least one rotor, an air gap being defined between each of said at least two stators and said at least one rotor and framed, at least one permanent magnet being carried by said at least one rotor, while a series of winding elements is carried by each stator being distributed successively, each of the winding elements comprising a tooth carrying a coil, each tooth being framed on each of its sides by a notch, said at least one magnet extending in the portion of the rotor between the two air gaps and each of the series winding elements comprising a non-coiled tooth between two teeth.
- the magnet is composed of a series of magnets each separated by intermediate pieces and is therefore discontinuous.
- it is a tooth similar to other teeth that does not wear winding that was taken as a separating element. It is therefore not possible in the engine according to this document to have a separating element which is smaller or larger than a tooth of the series or to have a separating element of a different material than tooth of the series.
- the document WO-A-93/15547 substantially repeats the features of the preceding document by showing a discontinuous magnet formed of several parts but without, however, disclosing a separating element between the winding elements.
- the problem underlying the present invention is, on the one hand, to obtain a radial flow electromagnetic motor which has the smallest possible space, in particular in its axial direction, and which can deliver a high mass torque and, d on the other hand, to reduce or even cancel the existing expansion torque in a polycarbonate motor with permanent magnets.
- an electromagnetic radial flow motor especially for assisting the power steering in a motor vehicle, the engine comprising at least a double air gap comprising at least at least two stators flanking at least one rotor, an air gap being defined between each of said at least two stators and said at least one rotor thus framed, at least one permanent magnet being carried by said at least one rotor, while a series of winding elements is carried by each stator being distributed successively, each of the winding elements comprising a tooth carrying a coil, each tooth being framed on each of its sides by a notch, characterized in that the rotor comprises a single magnet s' extending completely into the portion of the rotor between the two air gaps and in that each of the series winding elements comprises a separating element disposed between each notch of a tooth and the notch of the successive tooth.
- the present invention makes it possible to respond to power and space constraints in that it provides a high mass torque for a reduced diameter and an axial length smaller than the conventional structure with a single gap of the same diameter.
- the magnet or magnets occupy the whole place of the rotor between the two air gaps, so the maximum space provided for the magnet or magnets, which increases the efficiency of the engine and makes the engine much more compact.
- the magnet occupies the entire place of the rotor between the two air gaps, the magnet therefore extends in the largest possible space, which increases the efficiency of the engine and makes the engine much more compact.
- the magnet in one piece is easier to position between the two gaps than a series of magnets.
- each separation element when ferromagnetic, is used for channeling the magnetic flux emitted by the winding elements for both the internal stator and the outer stator, this between all the teeth.
- the invention further comprises at least any of the following:
- the separating element protrudes from the winding element in a manner similar to the teeth, that is to say having the same height.
- the teeth and the separation elements forming part of a series of winding elements of the same each stator have different widths.
- the teeth of the outer stator are offset relative to the teeth of the inner stator so that the apex angle at the center of the motor flanking a tooth width with its associated notches of the outer stator is offset with respect to the angle at the apex framing a tooth width with its associated notches of the internal stator.
- the teeth are made of plastic, composite, ceramic or glass material.
- the separating elements may be made of insulating material.
- the notches of all the winding series have means for channeling the magnetic flux.
- the notches are closed on most of their face vis-à-vis the associated air gap, a magnetic flux passage opening being present on said face.
- the two stators consist of several teeth of different shape and semi-closed notches in order to reduce the relaxation torque. In addition, this can affect the configuration of the magnetic flux emitted by the winding elements.
- said at least one rotor comprises several magnets, the coils of the series of winding elements of at least one stator being offset with respect to said magnets of said at least one rotor.
- said at least one magnet is chosen from ferrite magnets, rare-earth magnets such as neodymium-iron-boron magnets or samarium cobalt magnets, magnets based on aluminum, nickel and cobalt, with or without thermoplastic binder.
- the rotor and the stators are in cylindrical form.
- the rotor comprises a support for said at least one magnet, no part of the support being interposed between the two air gaps.
- said at least one rotor is connected to an output shaft of the motor passing through a median hollow cylindrical space to the motor traversing the motor axially, this median hollow space being delimited by the internal periphery of the internal stator.
- said at least one rotor is connected to the output shaft by a star-shaped piece.
- the diameter of the median hollow cylindrical space is greater than the diameter of the drive shaft so as to leave a passage between the drive shaft and the median hollow cylindrical space.
- the passage has ventilation means for cooling.
- the invention also relates to a power steering of a motor vehicle, characterized in that it contains at least one such motor.
- the engine according to the invention is very compact and relatively light because of the at least partial absence of iron, which makes it particularly well suited to use in a motor vehicle since a small footprint is an important criterion of choice in the automotive field.
- FIG. 1 is a diagrammatic representation of a radial cross-sectional view of an embodiment of a radial flux polycarbonate motor according to the present invention
- FIG. 2 is a diagrammatic representation of an axial sectional view of an embodiment of a radial flux polycarbonate motor according to the present invention
- FIG. 3 is a diagrammatic representation of a radial sectional view of another embodiment of a radial flux polycarbonate motor according to the present invention
- a motor M or a radial polycarrier generator comprises at least two stators 1, 1a flanking at least one rotor 2, a gap 4, 4a being defined between each of the at least two stators 1 1a respectively framing said at least one rotor 2. It is thus possible to define an internal stator a and an external stator 1, the latter forming the periphery of the motor M.
- the motor M consists of a rotor 2 comprising a series of permanent magnets 3 and two stators 1, 1a comprising a series of winding elements 5, 6, 7, 5a, 6a, 7a which will be described later. There is therefore an external gap 4 and an internal air gap 4a.
- Said at least one rotor 2 is connected to an output shaft of the motor passing through a median hollow cylindrical space 9 to the motor M passing through the motor M axially, the output shaft not being shown in the figures.
- the series of magnets comprises eight magnets, only one of which is referenced 3. This is not limiting.
- the stators 1, 1a are said to be wound, that is to say that they have a series of successive winding elements respectively composed of a winding of wire good conductor of electricity, for example aluminum or copper, a tooth 7, 7a and two notches 6, 6a flanking each tooth 7, 7a on each of its sides.
- a winding of wire good conductor of electricity for example aluminum or copper
- a tooth 7, 7a and two notches 6, 6a flanking each tooth 7, 7a on each of its sides.
- stator 1 a For each stator 1, only one tooth 7 and 7a, and one of their notches 6, 6a surrounding them are referenced by stator 1, 1 a.
- the notches 6, 6a are advantageously closed and individual.
- Each tooth 7, 7a serves as the core of a winding of the wire or winding.
- the number of teeth 7, 7a is preferably a function of the number of pairs of magnets 3 and the number of phases of the supply current.
- said at least one magnet 3 extends completely in the portion of the rotor 2 between the two gaps 4, 4a and each of the winding elements 5, 6, 7, 5a, 6a, 7a of the series comprises a separating element 5, 5a disposed between each notch 6, 6a of a tooth 7, 7a and the notch 6, 6a of the tooth 7, 7a successively.
- separation element 5, 5a characterizes an element located between two notches 6, 6a vis-à-vis winding teeth adjacent 7, 7a.
- This separating element 5, 5a may be of ferromagnetic material when the winding teeth 7, 7a are made of iron or of ferromagnetic material.
- the separating element 5, 5a may be of insulating material when the teeth 7, 7a do not contain iron.
- the teeth 7, 7a and the separation elements 5, 5a for each internal or external stator are part of the same element.
- a winding element according to the present invention therefore comprises a winding, a tooth 7, 7a for supporting the winding, a notch 6, 6a disposed on each side of the tooth 7, 7a and a separating element 5, 5a.
- the separating element 5, 5a advantageously projects from the winding element in a manner similar to the associated tooth 7, 7a, that is to say for example by extending substantially parallel to the associated tooth 7, 7a. and at the same height as this one.
- the teeth 7, 7a and the separating elements 5, 5a forming part of a series of winding elements 5, 6, 7, 5a, 6a, 7a of the same each stator 1, 1a can have different widths, the teeth 7, 7a may be wider than the separating elements 5, 5a. The opposite is possible, however.
- each stator 1 or 1 has formed one and the same piece carrying the teeth 7 or 7a, the separation elements 5 or 5a with notches 6 or 6a.
- the teeth 7 or 7a and the separation elements 5 or 5a are then based on the same material.
- the rotor 2 and the stators 1, 1a are in cylindrical form. This is not limiting because there may be other embodiments.
- the rotor 2 may be of cylindrical shape and the stators 1, 1 a in the form of crowns.
- the median hollow cylindrical space previously referenced 9 in FIG. 1 and delimited by the internal periphery of the internal stator 1 a, is occupied by a shaft 15 of the motor M which passes axially therethrough.
- the shaft 15 rotates by means of bearings 1 1, 1 1 has around a frame 13 housing the motor M, a portion of the frame 13 penetrating inside the median hollow space surrounding the shaft 15 .
- the rotor 2 is secured to the shaft 15 via a spacer 14 while the frame 13 is closed by a cover 12.
- the spacer 14 may be in the form of a starry part.
- the motor M comprises its electric part 1, 1a, 2 with its mechanical part 11, 15 housed inside the electrical part 1, 1a, 2 which makes it an extremely compact motor, advantageously closed by the frame 13 and its lid 12.
- the diameter of the median hollow cylindrical space is greater than the diameter of the shaft 15 surrounded by the portion of the frame 13 so as to leave a passage between the drive shaft and the median hollow cylindrical space.
- This passage advantageously has ventilation means for cooling, for example natural air brewing means or under the action of a fan incorporated in this hollow space.
- the present invention relates to a power steering of a motor vehicle containing at least one such motor M.
- the teeth 7 of the outer stator 1 are offset relative to the teeth 7a of the internal stator 1a so that the angle at the apex a5 at the center of the motor M framing a tooth width 7 with its two associated notches 6 surrounding the outer stator 1 is offset from the angle at the apex a4 framing a tooth width 7a with its two notches 6a associated with the inner stator 1a. It follows that the teeth 7 of the outer stator 1 do not individually have the same angle at the apex, a5 as the apex angle a4 for the teeth of the inner stator 1a can respectively be associated with them.
- FIG 3 there is visible an apex angle a3 which corresponds to a width of a notch 6 of the outer stator 1 and an apex angle a1 corresponding to a width of a notch 6a of the inner stator 1a. It is also shown an apex angle a2 corresponding to the difference in angle between one side of the notch 6a of the inner stator 1a and the corresponding side of the notch 6 of the outer stator 1.
- the teeth 7, 7a may contain iron as is the case in the usual manner. However, advantageously to reduce the relaxation torque, the teeth 7, 7a do not include iron. In this case, the teeth 7, 7a may be of plastic material, composite, ceramic or glass.
- the notches 6, 6a of all the winding series 5, 6, 7, 5a, 6a, 7a may have means for channeling the magnetic flux created by the coils.
- the notches 6, 6a are closed over most of their face vis-à-vis the air gap 4, 4a associated, an opening 10, 10a of magnetic flux passage being present on said face.
- This opening 10 for the external stator 1 or 10a for the internal stator 1a can take the dimensions or the desired shape for obtaining a magnetic flux of specific configuration.
- This opening 10, 10a can be different between notches 6, 6a of the inner stator 1a and the outer stator 1.
- said at least one rotor 2 comprises several magnets 3. In one embodiment shown in FIG. 3, said at least one rotor 2 comprises a single magnet.
- the rotor 2 may comprise a support for said at least one magnet 3, no part of the support being however interposed between the two air gaps 4, 4a, this support not being shown in the figures.
- the two sets of magnets 3 may have their successive magnets mounted according to a Halbach structure.
- Each concentric series of magnets 3 arranged according to a Halbach structure establishes an increased magnetic field on the side facing the series of winding elements 5, 6, 7, 5a, 6a, 7a associated with the stator 1, 1a vis-à-vis -vis, while the magnetic field is decreased or canceled on its opposite side. This reduces the loss of the magnetic field.
- At least one rotor 2 comprises several magnets 3, the coils of the series of winding elements 5, 6, 7, 5a, 6a, 7a of at least one stator 1, 1a being offset said magnets 3 of said at least one rotor 2.
- Said at least one magnet 3 may be chosen from ferrite magnets, rare earth magnets such as neodymium iron boron magnets or samarium cobalt magnets, magnets based on aluminum, nickel and cobalt, with or without thermoplastic binder.
