The rotor sheet is provided with a rotor sheet body, wherein starting rod slots are uniformly distributed along the outer circumference of the rotor sheet body; six magnetic steel slots are uniformly distributed on the rotor sheet body below the starting rod slots; an upper magnetic insulation bridge C is arranged between each starting rod slot and the main magnetic steel slot; the middle part of the rotor sheet body is provided with a rotor shaft hole; and the diameter phi of the rotor sheet body is between 250mm and 350mm.
Description
Technical field
What the utility model 280 Rare-earth PMSM Rotor Structure punchings related to is the punching of the synchronous operated three-phase rare-earth permanent-magnet synchronous electric motor rotor of a kind of asynchronous starting, belong to the rotor core punching of high synchronization rare-earth synchronous motor, can with supporting uses such as XYT-280S2-6 type textile motor, decelerator motor, pump motor, blower motor, compressor electric motor, injection molding machine motor, blow moulding machine motor, rubber and plastics machine motor.
Background technology
280 present Rare-earth PMSM Rotor Structure punchings, because the rotor punching structural design is reasonable inadequately, the running of can not pulling in smoothly behind the electric motor starting.Because the rotor punching structural design is reasonable inadequately, brings the unreasonable locked-rotor torque that causes of magnetic intensity bigger than normal, simultaneously, unreasonable the causing of back electromotive force is not economized on electricity.
Summary of the invention
The purpose of this utility model is to provide a kind of 280 Rare-earth PMSM Rotor Structure punchings at above-mentioned weak point, make rare earth permanent-magnet synchronization motor (the XYT-280S2-6 type that adopts this rotor punching to produce, wherein 280 is electric machine stand number, height of center is 280mm) both had a rational locked-rotor torque, rational pull up torque is arranged again, also have rational back electromotive force simultaneously, can satisfy corollary equipment and normally start, also have tangible power savings.
280 Rare-earth PMSM Rotor Structure punchings take following scheme to realize: 280 Rare-earth PMSM Rotor Structure punching structures have the rotor punching body, the external starting bar groove that is evenly distributed in of rotor punching, the rotor punching body is evenly equipped with six magnet steel grooves below the starting bar groove, described magnet steel groove is a radial V-type magnet steel groove, is provided with every magnetic bridge C between starting bar groove and magnet steel groove.Be provided with rotor shaft hatch at rotor punching body middle part.
Described rotor punching body diameter phi is 250～350mm.
Described starting bar slot length B is 5～18mm, and starting bar well width A is 1～10mm.
Described starting bar groove is provided with 40～70.
What be provided with between described starting bar groove and the magnet steel groove is 0.5～3mm every magnetic bridge C width upward.
The monolateral length D of described magnet steel groove is 10～100mm, and magnet steel well width E is 2～30mm.
Some rotor punchings were sleeved on to pressurize on the plug and tighten when 280 Rare-earth PMSM Rotor Structure punchings were used, be assembled into rotor core, in the startup groove groove of rotor core, insert starting bar, load onto the startup ring at the rotor core two ends, the welding of employing intermediate frequency, take out plug, send into the heating furnace heating, after the heating rotor core is taken out, hot jacket is on rotor main shaft, with spindle hole positioning car cylindrical, cleaning is also checked the magnet steel groove, embeds corresponding magnetic links in the magnet steel groove, and two ends are fixed with side plate, verification dynamic balancing on dynamic balancing machine, the rotor stator of packing into after verification is qualified.
Reasonable in design, the compact conformation of the utility model 280 Rare-earth PMSM Rotor Structure punchings.Adopt this rotor punching to produce rare earth permanent-magnet synchronization motor (XYT-280S2-6 type, wherein 280 is electric machine stand number, height of center is 280mm) have a rational locked-rotor torque, rational pull up torque is arranged again, also has rational back electromotive force simultaneously, can satisfy corollary equipment and normally start, and power savings is remarkable.This rotor punching shape is calculated and the verification experimental verification gained based on electromagnetism repeatedly.The utility model 280 Rare-earth PMSM Rotor Structure punchings are suitable for supporting uses such as XYT-280S2-6 type textile motor, decelerator motor, pump motor, blower motor, compressor electric motor, injection molding machine motor, blow moulding machine motor, rubber and plastics machine motor.
