Abstract
The utility model discloses a hybrid type motor rotor which relates to motors and discloses a technique. The motor rotor comprises a rotating shaft 1 on which rotor plates 4 formed by stacked silicon steel plates, aluminum end rings 3 and end plates 2 are arranged. The aluminum end rings 3 and the end plates 2 are orderly arranged on two ends of the rotor plates 4 on the rotating shaft 1. Two ends of a screw bolt 5 which orderly passes through holes of the end plates 2, holes of the aluminum end rings 3 and holes between rotor slots of the rotor plates 4 are meshed and welded with a nut 6. The motor rotor has the advantages of simple and compact structure, convenient manufacture and assembly, high safety performance and long service life (3 times longer than that of general rotors), and the motor rotor solves the problem that motors (in particular large power motors) are difficult to reach high speed. The motor rotor is suitable for high speed variable-frequency adjustable-speed motor rotors.
Description
One, technical field
The utility model relates to motor, especially a kind of mixed electric machine rotor.
Two, background technology
When the high speed, the rotor winding degree is wiped stator greatly, easily at existing squirrel cage motor rotor, and motor windings is easy to burn out.Traditional cage rotor all is to laminate cast aluminium with silicon steel sheet to form, when high-speed cruising, rotor loose easily sheet, fall aluminium, cause rotor to damage, motor speed such as can't improve at above-mentioned defective.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, mixed electric machine rotor firm in structure, that winding degree is little, security performance is high, the life-span is long, motor speed easily improves.
The technical scheme that the purpose of this utility model adopted is, include the rotor sheet, aluminium end ring, the end plate that silicon steel sheet are housed on the rotating shaft axle laminate, its rotating shaft axle upper rotor part sheet two ends are equipped with aluminium end ring and end plate successively, pass screw rod two ends and nut engagement welding behind the hole between the rotor grooved of the hole of hole, aluminium end ring of end plate and rotor sheet successively.
The utility model, aluminium end ring are enclosed within outward in the tubular position of end plate.
The utlity model has simple and compact for structurely, make easy to assemblyly, the security performance height in the life-span long (prolonging more than 3 times than common rotor), has solved motor (particularly heavy-duty motor) and has gone up difficult at a high speed problem.Suitable high speed frequency control motor rotor.
Four, description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is the utility model sectional structure schematic diagram.
Among the figure: 1-rotating shaft 2-end plate 3-aluminium end ring 4-rotor sheet 5-screw rod 6-nut
Five, embodiment
As shown in drawings, include in 1 of the rotating shaft rotor sheet 4, aluminium end ring 3, the end plate 2 that silicon steel sheet laminates is housed, 1 upper rotor part sheet 4 two ends of its rotating shaft are equipped with aluminium end ring 3 and end plate 2 successively, pass screw rod 5 two ends and nut 6 engagement welding behind the hole between the rotor grooved of the hole of hole, aluminium end ring 3 of end plate 2 and rotor sheet 4 successively.Aluminium end ring 3 outer being enclosed within the tubular position of end plate 2.
Operational mode of the present utility model is: rotor is installed in the motor stator, fixedly is the energising operation of coil stator central authorities with two end caps.
Claims (2)
1. mixed electric machine rotor, include rotor sheet (4), aluminium end ring (3), the end plate (2) that silicon steel sheet laminates is housed on rotating shaft (1) axle, it is characterized in that rotating shaft (1) axle upper rotor part sheet (4) two ends are equipped with aluminium end ring (3) and end plate (2) successively, pass between the rotor grooved of the hole of hole, aluminium end ring (3) of end plate (2) and rotor sheet (4) screw rod (5) two ends behind the hole successively and mesh with nut (6) and weld.
2. a kind of mixed electric machine rotor according to claim 1 is characterized in that being enclosed within the tubular position of end plate (2) outside the aluminium end ring (3).
