Description
Technical field
What the punching of the utility model in-line four groove Rare-earth PMSM Rotor Structure related to is the punching of a kind of asynchronous starting synchronous operated three-phase rare-earth permanent-magnet synchronous electric motor rotor, belong to the rotor iron core lamination of high synchronization rare-earth synchronous motor, can support the use with textile motor, decelerator motor, pump motor, blower motor, compressor electric motor, electric motor of injection machine, blow moulding machine motor, rubber and plastics machine motor etc.
Background technology
Current Rare-earth PMSM Rotor Structure punching, because rotor punching structure design is reasonable not, running of can not pulling in smoothly after electric motor starting.Because rotor punching structure design is reasonable not, brings the unreasonable locked-rotor torque that causes of magnetic intensity bigger than normal, meanwhile, unreasonable the causing of back electromotive force can be made again not economize on electricity.
Summary of the invention
The purpose of this utility model provides the punching of a kind of in-line four groove Rare-earth PMSM Rotor Structure for above-mentioned weak point, make the rare earth permanent-magnet synchronization motor that this rotor punching of employing is produced, both there is rational locked-rotor torque, there is again rational pull up torque, also has rational back electromotive force simultaneously, corollary equipment can be met normally start, also have obvious power savings.
The punching of in-line four groove Rare-earth PMSM Rotor Structure takes following scheme to realize: the punching of in-line four groove Rare-earth PMSM Rotor Structure has rotor punching body, rotor punching is external is evenly distributed in starting bar groove, also known as cage grooves, below starting bar groove, rotor punching body is evenly equipped with four magnet steel grooves, described magnet steel groove is radial in-line magnet steel groove, is provided with every magnetic bridge C between starting bar groove and magnet steel groove.Rotor shaft hatch is provided with in the middle part of rotor punching body.
Described starting bar groove is turriform, and bottom is trapezoidal, and top is rectangle.It is 10 ° ~ 60 ° that the rectangular top of described starting bar groove is provided with gradient α, the rectangular elevation H1 on starting bar groove top is 2 ~ 20mm, width A is 1.5 ~ 20 mm, the trapezoidal upper base width B of starting bar groove bottom is 2 ~ 20mm, the trapezoidal width F that goes to the bottom is 0.5 ~ 10mm, and trapezoidal height H 2 is 2 ~ 20mm.
Described rotor punching body diameter phi is 55 ~ 550mm.
Described starting bar groove is provided with 10 ~ 100.
On arranging between described starting bar groove and magnet steel groove every magnetic bridge C width be 0.5 ~ 3mm.
The described monolateral length D of magnet steel groove is 20 ~ 250mm, and magnet steel well width E is 1 ~ 40mm.
When the punching of in-line four groove Rare-earth PMSM Rotor Structure uses, some rotor punchings are sleeved on pressurization on plug and tighten, be assembled into rotor core, starting bar is inserted in the startup groove groove of rotor core, startup ring is loaded onto at rotor core two ends, employing intermediate frequency welds, take out plug, feeding heating furnace heats, after heating, rotor core is taken out, hot jacket is on rotor main shaft, with spindle hole positioning car cylindrical, clear up and check magnet steel groove, corresponding magnetic links is embedded in magnet steel groove, two ends side plate is fixed, dynamic balancing machine verifies dynamic balancing, through verify qualified after rotor load stator.
The punching of the utility model in-line four groove Rare-earth PMSM Rotor Structure is reasonable in design, compact conformation.Adopt this rotor punching to produce rare earth permanent-magnet synchronization motor and there is rational locked-rotor torque, have again rational pull up torque, also have rational back electromotive force simultaneously, corollary equipment can be met and normally start, and power savings is remarkable.This rotor punching shape is based on the checking of electromagnetism calculation and test repeatedly gained.The punching of the utility model in-line four groove Rare-earth PMSM Rotor Structure is suitable for textile motor, decelerator motor, pump motor, blower motor, compressor electric motor, electric motor of injection machine, blow moulding machine motor, rubber and plastics machine motor etc. and supports the use.
