Description
Technical field
What the punching of the utility model V-arrangement eight 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 V-arrangement eight 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 V-arrangement eight groove Rare-earth PMSM Rotor Structure takes following scheme to realize:
The punching of V-arrangement eight groove Rare-earth PMSM Rotor Structure has rotor punching body, rotor punching body is evenly equipped with eight magnet steel grooves, described magnet steel groove is radial V-type magnet steel groove, every magnetic bridge C on arranging, in the middle part of rotor punching body, is provided with rotor shaft hatch between two V-arrangement magnet steel groove ends.
Described rotor punching body diameter phi is 55 ~ 550mm.
On arranging between two described V-arrangement magnet steel groove ends every magnetic bridge C width be 0.5 ~ 20mm.
The described monolateral length D of magnet steel groove is 5 ~ 250mm, and magnet steel well width E is 1 ~ 25mm.
Described rotor punching body is provided with 4 ~ 20 louvres.
When the punching of V-arrangement eight groove Rare-earth PMSM Rotor Structure uses, some rotor punchings are sleeved on pressurization on plug and tighten, be assembled into rotor core, 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, and dynamic balancing machine verifies dynamic balancing, through verify qualified after rotor load stator.
The punching of the utility model V-arrangement eight 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 V-arrangement eight groove Rare-earth PMSM Rotor Structure is suitable for 315-6 type 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.
