Definitions
- the present invention relates to a synchronous machine that extracts electric power or generates torque by relatively rotating a field formed by a magnetized permanent magnet and a wound armature.
- DC generators, DC motors, synchronous generators, and synchronous motors can be broadly classified into armature rotating types and field rotating types, but those using permanent magnets are mostly field rotating types.
- the number of magnetic poles of the field and the number of armature poles are composed of 1: 1 and 1: 2 or an integer ratio.
- the permanent magnet of the field pole is magnetized in a direction perpendicular to the armature winding and rotates by itself. In order to make the magnetic field near the magnetic pole close to the desired value, some consideration is usually taken for the pole shape, air gap, etc.
- the permanent magnets of the field poles are magnetized at right angles to the relative rotation direction of the armature, so that when the poles face the armature balls, However, the strongest attraction force is generated, and at the same time, at the valleys of the magnetic poles, the attraction force decreases sharply, resulting in a strong cogging in the rotation of the armature. There was regret not done.
- An object of the present invention is to solve the above-mentioned problems in conventional generators and motors, namely, that cogging torque is large and rotation is not smooth, and that power generation efficiency is lower than mechanical input.
- Another object of the present invention is to provide a synchronous machine such as a synchronous generator and a synchronous motor having a small input and a large output, that is, high operating efficiency.
- the number of poles of the armature is ⁇ (where ⁇ is an integer), while the magnetic pole of the field is constituted by a plurality of permanent magnets, and the number of magnetic poles is ⁇ 1,
- the magnetization direction of the permanent magnet is set to the rotation direction of the armature or the field or the opposite direction, and the magnetizations of a plurality of permanent magnets are arranged to be inclined with respect to the axis of the rotational motion.
- the vehicle is moved relative to the vehicle.
- the armature has ⁇ poles ( ⁇ is an integer) and the polarity of the permanent magnet forming the field is ⁇ ⁇ 1, the pole of the permanent magnet and the pole of the armature are directly opposed. There is always only one pair, and no other is facing at the same time. And, since this pole is inclined with respect to the axis of the rotational movement of the field formed by the permanent magnet, within the range of the angle of ⁇ super over before and after the facing, between the two. The resulting suction force does not change significantly.
- FIG. 1 is a cross-sectional view of the entirety
- FIG. 2 is a front view of an armature core
- FIG. Fig. 4 shows a specific example of armature windings
- Fig. 4 is a front view of the permanent magnets constituting the field
- Fig. 5 is a partial orchid drawing showing the magnetized state of the magnet
- Fig. 7 is a circuit diagram showing the measurement state
- Fig. 7 is a characteristic diagram of the generated voltage, current, and torque due to the load when the rotational speed is changed.
- reference numeral 1 denotes a hollow fixed shaft, through which a rotating shaft 2 is rotatably mounted by a bearing 3.
- FIG. 3 illustrates the winding method for odd poles.
- A-phase windings and connecting wires are represented by solid lines, B-phase is represented by, and C-phase is represented by —————.
- 3 windings-a phase component is formed, 3 X 3 and 9 poles 1-
- a plurality of permanent magnets 7 are fixed so as to be located close to the outer periphery of the pole 4a of the armature core 4. I have.
- both poles are within the range of the crossover angle before and after the facing.
- the real suction force generated during the period does not change significantly.
- the S pole of the permanent magnet ⁇ constituting the field passes through the position 1 in FIG. 3, for example, and as the attraction of both weakens, the next position 2 and the other poles of the permanent magnet 7 Since the repulsive force between the N pole and the negative pole increases, the decrease in the real attractive force is offset. Therefore, since the relationship is close to the confrontation, the cogging torque fluctuation due to the sudden change in the attractive force of the pole 4 due to the pole of the permanent magnet 7 constituting the field is slight. Becomes
- one end of the coil 5 is connected to form a Y-shaped wire.
- the load R is a DC generator in which only one-way current flows.
- the pole of the permanent magnet 7 constituting the field since the pole of the permanent magnet 7 constituting the field is inclined, the change in the magnetic flux density generated in the ball 4 becomes small before and after facing the pole.
- the generated current is in a state close to the flat, so that the ripple voltage included in DC can be reduced.
- the rotation speed of the rotating shaft 2 Fig. 7 shows the generated voltage, generated current, and rotating torque at that time.
- the outer diameter of the armature core 4 used in this experiment was 39.4, the inner diameter of the permanent magnet ⁇ composing the field was 40, the coil 5 was 0.16 mm, and the copper wire with a diameter of 140 turns was wound.
- the line resistance is 9.3 ohm.
- the HI rotation may be performed not by the permanent magnet 7 constituting the outer field but by the inner armature.
- conventional brush means may be used for power extraction.
- the magnetization direction of a plurality of permanent magnets constituting the field of a rotating field type generator is set to the field or armature rotation direction, and the magnetization of a plurality of permanent magnets
- the magnetic path of NS becomes longer and the magnetic field distribution between NS becomes broad.
- the cogging torque in the crossover portion of the south pole and the south pole is small because the attractive force of the south pole and the repulsion of the south pole cancel each other.
- the armature pole is ⁇ and the pole of the permanent magnet that constitutes the field is ⁇ _ 1, even if only one armature pole and magnet pole face each other, it contributes to the reduction of cogging torque. I do.
- the magnetic flux density that cuts the armature winding has a maximum portion that is widened and flattened, so that it becomes close to a trapezoidal waveform, and the conversion efficiency is good when converted to direct current via a diode.
- the synchronous machine according to the present invention has a small mechanical energy loss and a small electric energy loss, and can provide a large output with a small input.
