The permanent magnet 4 of present embodiment comprises the first permanent magnet 4a and the 2nd permanent magnet 4b.
1st permanent magnet 4a is positioned at the position clipped by the magnetic barrier 12a of the magnetic barrier 12aa in outside and inner side.Now, magnetic barrier 12aa is positioned at the position than 12a outer circumferential side side (stator side), and the length of each magnetic barrier becomes 12a > 12aa.The 1st above-mentioned permanent magnet 4a is arranged to 2 and centered by d axle line symmetrical.Using this 1 couple as the 1st permanent magnet group.
2nd permanent magnet 4b is positioned at and is clipped and the position of ratio the 1st permanent magnet 4a outer circumferential side side (stator side) by the magnetic barrier 12b of the magnetic barrier 12bb in outside and inner side.Now, magnetic barrier 12bb is positioned at the position than magnetic barrier 12b outer circumferential side side (stator side), and the length of each magnetic barrier becomes 12bb > 12b.The 2nd above-mentioned permanent magnet 4b is arranged to 2 and centered by d axle line symmetrical.Using this 1 couple as the 2nd permanent magnet group.
In addition, the end of the magnetic barrier 12aa side of the 1st permanent magnet 4a is positioned at or nonoverlapping position roughly equal with the end of the magnetic barrier 12a side of the 2nd permanent magnet 4b.In other words, be configured to towards armature spindle 9 direction, each permanent magnet be located in rotor 5 is not overlapping.
In addition, the first bridge part 13a is clipped by the magnetic barrier 12a being become symmetry centered by d axle.In addition, using near the first bridge part 13a as the first narrow portion of magnetic circuit.In addition, the second bridge part 13b is clipped by the magnetic barrier 12b being become symmetry centered by d axle.In addition, using near the second bridge part 13a as the second narrow portion of magnetic circuit.
Armature spindle 9 is provided with in the inner circumferential side of rotor 5.Armature spindle 9 is rotatably supported by the bearing with roll shaft, ball axle etc. not shown here.
In addition, also can be configured to, when drawing the normal on the outer peripheral face of this armature spindle 9 towards the outer peripheral face of rotor 5, be present on this line when the first permanent magnet 4a is different with the 2nd permanent magnet 4b both sides.
In the armature winding 3 of the stator 1 of the permanent magnet type reluctance rotary motor formed like this, produce rotating magnetic field due to current flowing.Rotor 5 is attracted by the rotating magnetic field being produced, and rotates centered by armature spindle 9.Rotor core 8 has respectively along the radial direction of rotor core 8 or being easy to magnetized axis (part that magnetic flux easily passes through) q and being difficult to magnetized axis (magnetic flux is difficult to the part passed through) d of radiation direction extension, and these q axles and d axle are determined by the allocation position of permanent magnet 4.Therefore, rotor core 8 circumferentially alternately and with regulation phase place formed.
In the explanation of the 1st execution mode, be illustrated as an example with 2 layers of magnet configuration, but be not limited to 2 layers.

From mathematical expression 1, by increasing the ratio of Lq/Ld, reluctance torque (Tr) can be improved, and combine, so the efficientibility produced relative to the torque of electric current can be sought due to reluctance torque (Tr) and magnet torque (Tm).In addition, from mathematical expression 2, the both sides by inductance and permanent magnet magnetic flux affect and decide terminal voltage.In order to obtain the characteristic of best motor in the voltage be endowed, electric current, need magnet region that suitably controlling magnet magnetic flux is such to guarantee the structure in rotor cross section.
In order to realize structure as described above, need the structure making reluctance torque (Tr) and magnet torque (Tm) appropriate balance.Make the maximized shape of ratio of Lq/Ld, be become maximum mode with the axial magnetic flux of q to form magnetic circuit on iron core, and become with the axial magnetic flux of d the rotor shapes that minimum mode is provided with permanent magnet 4 and magnetic barrier 12.In addition, in order to suitably control voltage, have to be formed as to make magnet magnetic flux than from the weak magnet configuration of the armature flux of stator side.
Fig. 3 represents the comparison of the torque-speed characteristic having permanent magnet 4 stacked permanent magnet type reluctance rotary motor and have the not stacked permanent magnet type reluctance rotary motor of permanent magnet 4.Represent in figure 3 and there is the stacked torque-speed characteristic of permanent magnet 4 81 and there is the not stacked torque-speed characteristic 80 of permanent magnet 4.The torque that the nonoverlapping torque-speed characteristic of permanent magnet 4 80 is larger than the torque-speed characteristic 81 of permanent magnet 4 overlap can be exported during representing the rotating speed more than 5000 in figure.In other words, owing to making permanent magnet 4 not overlapping, in ~ high speed time torque export improve.
