Abstract
The utility model provides a detachable assembling type permanent-magnetic motor rotor comprising a magnetic pole iron core, a rotor bracket and a rotor pressing ring. The magnetic pole iron core is composed of more than two counter-pole magnetic pole iron core units, the counter-pole magnetic pole iron core units are assembled into a whole by a tightening screw rod after being magnetized, the rotor pressing ring is fixed at the end part of the magnetic pole iron core by a nut at the end part of the tightening screw rod, and the magnetic pole iron core is fixed on the outer surface of the rotor bracket along the circumferential direction by a bolt. The detachable assembling type permanent-magnetic motor rotor is easy for installation and convenient for maintenance.
Description
Technical field
The utility model relates to a kind of permanent magnet machine rotor, especially relates to a kind of detachable assembled permanent magnet machine rotor.
Background technology
At present, known rotor structure for permanent magnet motor, its rotor core integral body laminates and is one, and the magnet steel that magnetizes after finishing embeds iron core respectively, and iron core is installed on the rotor field spider.In embedding the magnet steel process, because magnet steel is magnetized, must overcome the magnetic force of magnet steel, bring inconvenience to telescopiny; The ruined situation of magnet steel coating also happens occasionally; And when certain magnet steel goes wrong, need unload whole magnet steel of whole magnetic pole, maintenance causes difficulty to rotor.
The utility model content
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and provides a kind of installation easy, detachable assembled permanent magnet machine rotor easy to maintenance.
The technical solution of the utility model is: it comprises pole core, rotor field spider and rotor pressing ring, pole core is made up of plural a pair of utmost point pole core unit, a pair of utmost point pole core unit after magnetizing is assembled into one by stretching screw, rotor pressing ring is fixed in the pole core end by the nut of stretching screw end, and pole core is along the circumferential direction gone up by being bolted to the rotor field spider outer surface.
A pair of utmost point pole core unit comprises two blocks of magnet steel that magnetize, an iron core unit, and magnet steel inserts in the iron core unit.
The utility model is owing to be divided into plural a pair of utmost point pole core unit with pole core, again by being bolted on the rotor field spider, assembling and dismounting are all very convenient, because a pair of utmost point pole core unit volume is less, in installation process, after can magnetizing to a pair of utmost point pole core unit that assembles magnet steel earlier, be fixed on again on the rotor field spider, install and the process that magnetizes simple.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is an a pair of utmost point pole core cellular construction enlarged diagram embodiment illustrated in fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to Fig. 1, present embodiment comprises pole core 10, rotor field spider 7 and rotor pressing ring 6, pole core 10 is made up of 11 a pair of utmost point pole core unit 9,11 after magnetizing a pair of utmost point pole core unit 9 are assembled into one by stretching screw 3, rotor pressing ring 6 is fixed in pole core 10 ends by the nut 4 of stretching screw 3 ends, and pole core 10 is fixed on rotor field spider 7 outer surfaces and along the circumferential direction goes up by bolt I 8-1, bolt II 8-2, bolt III 8-3.
With reference to Fig. 2, a pair of utmost point pole core unit 9 comprises the magnet steel I 1-1 that magnetizes, the magnet steel II 1-2, the iron core unit 2 that magnetize, and magnet steel I 1-1, magnet steel II 1-2 insert in the iron core unit 2.
