Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reluctance type electric motor and a reluctance type rotating machine such as a reluctance type rotary solenoid, in which each magnetic pole is provided independently so that the magnetic path of the armature magnetic pole of a stator is closed for each magnetic pole. It is something.

[Conventional technology]

Each magnetic pole of a conventional fixed armature is provided independently, and a roughtance type rotating machine is fixed by placing each of the above magnetic poles in the center of the inner circumferential surface of an outer cylinder formed to have the same diameter as the outer circumferential surface of the armature magnetic pole. However, rotary shaft bearing supports were fitted to both ends of the inner circumferential surface of this outer cylinder.

[Problem that the invention seeks to solve]

For example, in the case of a conventional glue raftance nose rotating machine such as this, in the case of an inner rotor, the magnetic poles on the inner circumferential surface of the outer cylinder are fitted and fixed, making the assembly of the stator complicated and the rotating machine difficult to assemble. There was a problem that productivity decreased. Furthermore, there is a problem in that the gap between the opposing rotating surfaces of the magnetic poles of the stator and the salient poles of the rotor becomes large, causing vibrations during rotation.

[Means for solving problems]

In order to solve the above-mentioned problems with the conventional ones, the present invention provides a rotor with a rotating surface at the tip and salient poles formed with equal spacing and equal width, and a rotor with a U-shape having both ends at a right angle. A plurality of armatures each having a magnetic pole bent to have rotating surfaces at both tips and an excitation coil for exciting these are arranged so that the rotating surfaces at both tips of each of the magnetic poles extend in the circumferential direction. Controls the energization of the stator and the excitation coil, which are arranged on the circumference at equal intervals so as to face the rotating surface of the rotor so that they are lined up and are integrally molded with synthetic resin except for at least the rotating surface of the armature. The current supply control circuit is configured to include an energization control circuit.

[Effect]

According to the above-described means of the present invention, the stator is integrally molded except for at least the rotating surfaces so that each rotating surface of the plurality of armatures and each rotating surface of the rotor face each other with a constant small gap. The rotary machine is assembled by inserting the stator into the outer cylinder, so the assembly work is easy. Further, the error in the gap between the opposing rotating surfaces of the magnetic poles of the stator and the rotating surfaces of the salient poles of the rotor is reduced.

〔Effect of the invention〕

As explained above, the reluctance type rotating machine according to the present invention has the effect that the assembly work of the one-rotation machine is facilitated and that vibrations due to errors in the busy gap do not occur. Furthermore, since the magnetic poles are U-shaped, there is no magnetic flux leaking to other magnetic poles (which has the effect of increasing output torque).Also, since the number of salient poles is small, the inertia of the rotor can be reduced.
