The permanent magnet fixation member 290 can integrally secure bond in the permanent magnet engaging portion 270.
For example, the permanent magnet fixation member 290 can integrally be incorporated into the permanent magnet knot by binder
Conjunction portion 270.
For example, the permanent magnet fixation member 290 can be set to and the permanent magnet engaging portion 270 screw knot each other
It closes.
In addition, for example, the permanent magnet fixation member 290 can be set to and 270 welding of permanent magnet engaging portion
In conjunction with.
It, can also be with shape although illustrating the situation that the permanent magnet 222 is formed as circular in the present embodiment
As circular shape.
The permanent magnet 222 can be set to along the circumferential direction configure magnetic pole different from each other.
In the settable Magnetic Sensor 310 in the side of the permanent magnet 222, the Magnetic Sensor 310 for detect it is described forever
The magnetic field of long magnet 222.
For example, the Magnetic Sensor 310 can have the Hall sensor (Hall using Hall effect (Hall effect)
Sensor) 314, the Hall effect (Hall effect) is to be formed in the conductor by electric current perpendicular to current direction
When magnetic field, potential difference is generated on the direction vertical with electric current in conductor.
The Magnetic Sensor 310 can have multiple Hall sensors 314.
For example, as shown in figure 14, the Magnetic Sensor can have substrate 312 and is configured in a manner of separated from each other described
Multiple Hall sensors 314 of substrate 312.
The multiple Hall sensor 314 can separate configuration on the same circular arc of the periphery of the permanent magnet 222.
For example, the Magnetic Sensor 310 may be disposed at the supporting substrate 247 of the inverter 240.
Though it is not illustrated, being that the Magnetic Sensor 310 can communicatively be connected with control unit, with energy
Enough output test results.
For example, the substrate 312 of the Magnetic Sensor 310 can have: cable 315, with can be with the Hall sensor 314
The mode of transmission signal is connected with the Magnetic Sensor 310；And connector 317, one side are connected with the cable 315
The other side is connect with different connector.
According to this structure, the permanent magnet engaging portion 270 of the main part 262 of permanent magnet 222 and the slip ring 260b
It combines, the permanent magnet fixation member 290 can be by integrally secure bond.
The end of the rotary shaft 161 and each end part of the rotor coil 181 are incorporated into the slip ring 260b
It is not incorporated into after the connection sheet 285 of the leg 280 of the slip ring 260b, the connection sheet 285 can be plastically deformed respectively.
The supporting substrate 247 of the inverter 240 can be combined with the periphery of the slip ring 260b, in the permanent magnet
It can configure the Magnetic Sensor 310 on 222 periphery.
In addition, power supply is fed separately to the stator coil 141 and the rotor coil 181 if starting running,
Interaction by the magnetic field being respectively formed by the stator coil 141 and rotor coil 181, the rotor 160 can be with
The rotary shaft 161 pivots about.
If the rotary shaft 161 is rotated, the slip ring 260b is rotated, and the Magnetic Sensor 310 is able to detect
The magnetic field of the permanent magnet 222 is simultaneously output to the outside as detection signal.
More than, the specific embodiment of the utility model is had been shown and described.But it can be not depart from this practical new
It in the range of the technical idea or substantive characteristics of type, is realized with variform, therefore, embodiments illustrated above is not limited to it
The content of detailed description.
In addition, the embodiment that do not listed one by one in detailed description hereinbefore even, it should also in claims
Defined in its technical idea in the range of be broadly construed.Also, the technical scope of claims and be included in
All changes and deformation in its equivalency range, should all fall into the protection scope of claims.
