The rotor is characterized in that the rotating shaft 3 and the rotor core 1 are matched and fixed via a key slot, a rotor pole comprises one or more of the magnets 6 which are arranged in homopolar and adjacent sequence, each of the magnets 6 is embedded into a slot of the rotor core 1, the shaft-used block ring 4 is positioned on the rotating shaft 3 at one end of the rotor core 1, the baffle 5 is arranged at two ends of the rotor core 1 and outside the shaft-used block ring 4, and the fastener 2 fastens the rotor core 1 therein via the baffle 5. The rotor for the magnetoelectric machine has high mechanical strength and efficiency, low temperature rise, less magnetic leakage and loss as well as convenient processing and assembly, thereby being applicable to various small and medium magnetoelectric machines.
Description
One, technical field
The utility model relates to a kind of rotor, particularly a kind of permanent magnet machine rotor.
Two, background technology
At present, conventional middle low power permanent magnet machine rotor, iron core all are to adopt punching silicon-steel to laminate or adopt cast steel to process basically; Magnetic patch is bonded in iron core surface or fastening with screw with special-purpose adhesive glue.Though said structure has the stock utilization height, advantage such as the magnet steel consumption is few; But when motor when running up, magnetic patch bonding is not firm, causes motor stator, rotor to wipe mutually, burns motor; Moreover permanent magnets is hard and crisp, and single magnetic patch arc is big, magnetic patch critical defect such as very easily rupture.
Three, summary of the invention
The purpose of this utility model provides a kind of rotor magnetic pole sound construction, and leakage field is little, and process and assemble is convenient, the permanent magnet machine rotor that efficient is high.
Permanent magnet machine rotor of the present utility model, comprise rotor core, securing member, rotating shaft, axle ring washer, baffle plate, magnetic patch, its feature adopts keyway to cooperate between rotating shaft and rotor core and fixes, rotor magnetic pole is made up of one or more magnetic patch of arranging by the homopolarity adjacent sequential, every magnetic patch is embedded in the rotor core groove, one end of rotor core has shaft block ring to locate in rotating shaft, baffle plate is positioned at the two ends of rotor core and outside shaft block ring, securing member by the fastening rotor core of baffle plate in wherein.
So both solved the not firm problem of rotor magnetic patch bonding, the magnetic patch of arranging by one or more homopolarity adjacent sequential is combined into a magnetic pole simultaneously, it is big to have solved the single magnetic patch arc of magneto dexterously, the problem of assembling easy fracture, the design of rotor simultaneously can guarantee requirement of mechanical strength, also can reduce leakage field significantly.
Four, description of drawings
Fig. 1 is the structural representation of the utility model permanent magnet machine rotor.
Fig. 2 is the left view of the utility model permanent magnet machine rotor.
Five, embodiment
Structure below in conjunction with description of drawings utility model permanent magnet machine rotor embodiment:
This permanent magnet machine rotor is made up of rotor core 1, securing member 2, rotating shaft 3, shaft block ring 4, plate washer 5, magnetic patch 6; Rotor magnetic pole is rearranged by the homopolarity adjacent sequential by one or more magnetic patch 6, and magnetic patch 6 is the arc magnetic patch, and magnetic patch 6 places in rotor core 1 groove, and rotor core 1 is sealed in magnetic patch 6 wherein; Rotating shaft 3 is adopted keyway to cooperate with rotor core 1 and is fixed, rotor core 1 one ends position in rotating shaft 3 with shaft block ring 4, prevent rotor core 1 axial endplay, place behind rotor core 1 two ends plate washer 5 fastening with securing member 2, rotor core 1 is anchored between 2 plate washers 5, owing to magnetic patch 6 is anchored in rotor core 1 groove, and is sealed in the rotor core 1, therefore motor can not come off when running up yet, and leakage field is little.
Rotor design should guarantee the requirement of mechanical strength of motor high speed rotating, also need guarantee significantly to reduce the rotor magnetic circuit leakage field.After this permanent magnet machine rotor was assembled into motor, magnetic patch (6) was not exposed in the motor stator and rotor air gap.
The permanent magnet machine rotor that most preferred embodiment adopts for the 7.5KW magneto alternator, the external diameter of its rotor core 1 is φ 215mm, and length is 80mm, and magnetic patch 6 is of a size of 55mm * 6mm * 80mm.When the rotor number of poles is two utmost points, can obtain following performance: during 3600r/min, motor two-phase output voltage is 240V, power 7.5KW, and electric efficiency is greater than 90%.
This p-m rotor is specially adapted to the dipolar permanent motor, its mechanical strength height, and temperature rise is low, and leakage field is little, and loss is little, the efficient height, structure is convenient to processing and streamline assembling, and is beneficial to the q﹠r that improves rotor, is applicable to various middle-size and small-size magnetoes.
