Definitions
- the toroidal coils may comprise two serially connected coil segments.
- the reluctance motor preferably has a control unit, wherein the toroidal coils can be controlled by means of the pulse width modulation (PWM) control unit. It is advantageous if the control unit has an inverter for energizing the toroidal coils.
- PWM pulse width modulation
- a steer-by-wire steering system for motor vehicles comprising a steering actuator acting on the steered wheels, electronically controlled in response to a driver's steering request, acting on the steered wheels by means of a steering gear, and feedback on feedback associated with a steering shaft connected to the steering wheel Actuator provided, wherein the feedback actuator comprises a reluctance motor described above.
- a method for mounting a reluctance motor described above is provided with the following steps: Providing a longitudinally extending mounting mandrel which ensures relative alignment of the stator segments with each other,

- FIG. 27 shows a schematic representation of a further circuit of a four-phase reluctance motor
- Fig. 28 a schematic representation of a circuit of a four-phase
- FIG. 29 shows a schematic longitudinal section through a stator segment with two.
- FIG. 1 shows a steer-by-wire steering system 1.
- a steering shaft 2 mounted on a steering shaft 2 is an unillustrated rotational angle sensor, which detects the driver steering angle applied by rotating a steering input means 3, which in the example is designed as a steering wheel. However, additionally or alternatively, a steering torque can also be detected.
- a feedback actuator 4 is mounted on the steering shaft 2, which serves to simulate the repercussions from the roadway 5 to the steering wheel 3 and thus to give the driver feedback about the steering and driving behavior of the vehicle.
- the driver's steering request is transmitted via the rotational angle of the steering shaft 2 measured by the rotational angle sensor via a signal line 6 to a control unit 7.
- the control unit 7 transmits the driver's steering request via a signal line 8 to an electric steering actuator 9, which controls the position of the steered wheels 10.
- the steering actuator 9 acts via a steering-rod steering gear 11, such as a rack-and-pinion steering, and via tie rods 12 and other components indirectly to the steered wheels 10.
- the control unit 7 preferably takes over the control of the feedback actuator 4 via a signal line thirteenth.
- Control unit 7 furthermore receives signals from sensors 15 from the steering gear 11 via a signal line 14.
- FIG. 2 shows a feedback actuator 4 with a reluctance motor 16 according to the invention.
- the term reluctance motor is broadly understood to mean motors in which a variable magnetic field is generated by a stator, and the rotor usually has poles without windings of ferromagnetic material, the rotor striving for a position in the magnetic field minimal reluctance align.
- the orientation of the magnetic field in the stator can be gradual or continuous with respect to the center of rotation of the rotor
- an air gap 28 may arise, which adversely affects heat dissipation. It may therefore be provided in the air gap 28, a thermal grease or adhesive, which promotes heat dissipation.
- Per phase two stator 20 and a coil 26 are provided.
- the reluctance motor 16 shown in Figure 2 has a total of three phases.
- Interconnection of the coils can be dependent (eg neutral connection) or independent (single control).
- FIGS. 6 and 7 show two positions of a stator segment 20 of the reluctance motor 16.
- the air gap between the rotor 18 and the stator segments 20 is as small as possible and thus the reluctance is minimal.
- the teeth of the rotor 19 and the stator 30 are opposite.
- the position of minimum reluctance with active field winding of the second phase 39 is shifted by Z / 3 in the direction of rotation, and shifted by 2/3 * Z in the direction of rotation when the third phase 40 is active field winding.
- the rotor can be rotated by targeted energization of the individual phases 38,39,40 in rotation.
- FIG. 11 shows the orientation of the teeth 30 of the stator segments 24.
- the tooth pairs of a stator segment 24 are arranged axially aligned and have no offset. But it can also be provided to offset individual sprockets of a stator segments against each other, for. B. by 1/2, 1/4 or 1/3 of the tooth spacing Z.
- the number of teeth along the circumference is preferably greater than 30, more preferably greater than 50.
- Figure 13 a) -o) shows a method of assembling the reluctance motor 16.
- Mounting mandrel 46 is provided, which ensures the relative alignment of the stator segments 24 to each other (angular position).
- the mounting mandrel 46 has six stator pins, not shown, which can be retracted and extended together via a mechanism.
- the stator pins engage in the toothing of the stator segments 24.
- the risk of unwanted rotation of the sprockets of the stator 24 is prevented during the assembly process.
- the second end plate 341 is placed on a seat on the mounting mandrel 46. This is followed by inserting the wave spring 41 before the stator pins are extended. Thereafter, the sixth stator ring 20 on the
- Assembly mandrel 46 placed, followed by the third annular coil 26 and the fifth stator ring 20.
- a spacer 37 separates the fifth stator ring 20 from the fourth stator ring 20 which is placed on the spacer 37.
- the second toroidal coil 26, the third stator ring 20, a further spacer 37, the second stator ring 20, the first toroidal coil 26 and the first stator ring 20 are placed on the mounting mandrel 46 in turn.
- a spacer 37 is placed on which the bearing 36 is placed.
- the first end plate 340 is placed, which has a seat for the fixed bearing 36. By pressure on the first end plate 340, a bias voltage is generated. This bias is preferably about 50kN.
- the two end plates 340, 341 are then fastened to one another by means of the connecting screws 35.
- the connecting screws 35 are on
- This assembly process is particularly simple and qualified by the small number of tools required, a mounting mandrel 46 and a wrench.
- FIG. 14 shows a reluctance motor 16 with a magnetized rotor 18.
- the reluctance motor 16 has only two stator segments 24, which are arranged offset according to Figure 15 against each other in the circumferential direction.
- the ring gear is preferably magnetized or has permanent magnets. The magnetization superimposes reluctance forces on Lorentz forces. Lorentz forces are dependent on the flow direction of the magnetic field. The uniqueness of the rotation thus results from the direction of the coil current.
- the advantage of this arrangement is that only two stator segments are used, resulting in a higher
- FIGS. 19, 20 show a variant of the reluctance motor 16 as external rotor.
- the toothing 30 of the stator 20 is located on the outside and the terminals 32 on the inside.
- the rotor 18 surrounds the stator segments 24 and has, as shown in Figure 20, on the inside of the teeth 19.
- Figures 23-25 show embodiments with magnetized rotor 18. Individual magnets or multimagnetized magnets (one-piece magnet with different magnetized areas) may be used.
- FIG. 23 shows a magnetized and multipart rotor 18 with alternating magnetization along the longitudinal axis 100 in the radial direction magnetic flux 44 passes through the stator segment 24, the rotor 18 and the hollow shaft 45.
