Abstract
The invention relates to a magnetic steel arranging method of motor rotors, in particular to an arranging method of high-speed groove drum motor rotor magnetic steel, which is matched with an automatic winder in fine yarn spinning industry. In the arranging method of the high-speed groove drum motor rotor magnetic steel, thirteen magnetic steels (1) on a high-speed groove drum motor rotor are arranged, and the arranging way is that: the magnetic steels are uniformly distributed by taking an iron core (2) as a center, and are surrounded by a stainless steel sheath (3). The magnetic steel is provided with N pole and S pole at the same time, so as to lead the rotor not to have clearance weak magnetism in the high-speed operation pole-exchange process. The method can lead the high-speed groovedrum motor rotor matched with the automatic winder not to generate jitter in the using process, so as to ensure stable operation, low noise, low power consumption, low temperature rising and less faults under the condition that the groove drum motor is in high load for a long time, thereby practically solving the difficult problem of domestication of the high-speed groove drum motor.
Description
Technical field
The present invention relates to a kind of magnet steel aligning method of rotor, the aligning method of a kind of high-speed groove drum motor rotor magnetic steel that relating in particular to matches with the spun yarn industry automatic winder of weaving uses.
Background technology
The rotor of high-speed groove drum motor is made by permanent magnetic material, has the permanent magnet of certain magnetic pole logarithm, and the structure of rotor is general to adopt the permanent magnet with tile to be attached to rotor in appearance, i.e. salient pole type.In order to produce trapezoidal induced electromotive force, the shape of the rotor magnetic steel of high-speed groove drum motor curved (tile), the rotor air gap is even under the magnetic pole, air-gap field is trapezoidal profile, armature is arranged on the stator, and the stator armature winding adopts whole apart from centralized winding, and the number of phases of winding adopts three phase windings, each phase winding links to each other with the electronic switching circuit of outside respectively, and the switching tube in the switching circuit is subjected to the signal controlling of position transducer.DC power supply is powered to the motor stator winding by switching circuit, position transducer detects the residing position of rotor at any time, and come the conducting of control switch pipe and end according to the position signalling of rotor, thereby automatically controlled the energising and the outage of winding, realized the stator commutation.In the process of commutation, each phase winding of stator formed rotating magnetic field in working gas gap is a spasmodic motion, and they follow the tracks of rotor, and with the magnetic field interaction of rotor, can produce and promote the torque that rotor is rotated further.During the groove drum high-speed cruising of domestic production jitter phenomenon is arranged easily, the epitrochanterian magnet steel of one of the main reasons magnetizes inhomogeneous, and weak magnetic dot is arranged between the number of poles; Rotor upper magnetic steel number of pole-pairs is equipped with unreasonable, the magnetic density unevenness is even, the low requirement that causes groove drum can not satisfy long-term high rotating speed operation of magnetic density especially during the broiling summer, the torque instability occurs especially, the rotor poor rigidity, rotor is beated greatly, and electric current is big, the power consumption height, heating is serious, and temperature rise is too high and burn.
Obtain high speed (7000rpm) operation of groove drum, groove drum must have big torque, and wide speed adjustable range is when running in continuous 24 hours, necessary running steadily, noise is low, low in energy consumption, temperature rise is low, so most important to the research of rotor and epitrochanterian magnet steel (permanent magnet).If have only the N or the S utmost point on the every magnet steel outer surface, so, during the rotor running, promptly from N → S or S → N, when change poles can be caused in the gap of magnetic steel ingot, the groove drum that runs up had jitter phenomenon.
Summary of the invention
The present invention is in view of problems of the prior art, provide a kind of rationally scientifically method be equipped with epitrochanterian magnet steel, utilize particular manufacturing craft accurately to magnetize, allow and all have N, the S utmost point simultaneously on every block of magnet steel, stop to cause weak magnetic because of the magnetic steel ingot gap, make change poles finish in same block of magnet steel, groove drum will be steady at high-speed cruising.
In order to achieve the above object, the aligning method of the high-speed groove drum motor rotor magnetic steel that the present invention relates to, 12 blocks of magnet steel that break traditions in the magnet steel configuration of rotor distribute, adopted tridecyne magnet steel arranged distribution, and allow all have N, the S utmost point simultaneously on every block of magnet steel, make rotor in the process of change poles that runs up, not have the gap a little less than magnetic.
The present invention can in use not produce jitter phenomenon by the high-speed groove drum motor rotor that use so that automatic winder matches, running steadily under the situation of long-term high capacity, noise is low, low in energy consumption, temperature rise is low, fault is few can to guarantee groove drum, solves the difficult problem of high-speed groove drum motor production domesticization conscientiously.
