Embodiment Construction

[0043] Below, the content of the present invention will be described in detail in conjunction with the drawings and embodiments.

[0044] image 3 It is a schematic plan view of the rotor of the single-phase start-up reluctance motor of the present invention. Such as image 3As shown, the rotor 10 includes an iron core 11 with a shaft joint 12 formed in the direction of the combined rotating shaft (not shown in the figure), several magnetic bar insertion openings 13 formed around the iron core 11, and the magnetic bar insertion openings 13 Insert several magnetic rods 14 in. Furthermore, the iron core 11 includes: a plurality of magnetic fluxes extending perpendicular to a first axis perpendicular to a direction coupled to the rotation axis (hereinafter referred to as "coupling direction") and symmetrical to each other around a second axis perpendicular to the first axis. Shielding layer 15 constitutes. Also, the portion of the core 11 between the plurality of magnetic flu...

Abstract

A single-phase starting up type magnetic resistance motor rotor includes: axle combining port, iron core with number of magnetic bar inserting, number of magnetic bar inserting in magnetic bar inserting port, number of flux shield layer, said flux shield layer approaching inserting port. The present invention has function for clearing opposing torque, providing maximal power and efficiency, preventing generating magnetic saturation phenomena in iron core, and making magnetic flux flow more volubility.

Description

technical field [0001] The invention relates to an electric machine. In particular, it relates to a rotor of a single-phase start-up reluctance motor that includes a bar magnet insertion opening where no bar magnet is inserted, thereby preventing reverse torque. Background technique [0002] The single-phase start-up reluctance motor is a single-phase power AC motor that moves at a constant speed, and is a hybrid form of an induction motor and a reluctance motor. The single-phase start-up reluctance motor includes: a stator that forms a rotating magnetic field by the AC power supplied to the winding; a rotor that is located inside the stator and rotates under the action of the rotating magnetic field generated by the stator. Single-phase start-up reluctance motors use the rotational force when the rotor moves in the direction where the reluctance (electromagnetic resistance) decreases when the stator magnetic flux passes through the rotor. That is to say, when starting, li...
