Abstract
The utility model discloses a high strength motor rotor which relates to motors and discloses a technique. The motor rotor consists of rotor plates 3 formed by stacked silicon steel plates, end plates 2 and aluminum end rings 5, which are arranged on a shaft 1. The aluminum end rings 5 and the end plates 2 are orderly arranged on two ends of the rotor plates 3 on the shaft 1. Groove welding seams 4 are arranged axially on the outer circle walls of the end plates 2 and the rotor plates 3. The motor rotor has the advantages of simple and compact structure, convenient manufacture and assembly, high safety performance and long 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 motors.
Description
One, technical field
The utility model relates to motor, especially a kind of high strength 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, high strength 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, end plate, the aluminium end ring composition that silicon steel sheet are housed on the axle axle laminate, its axle upper rotor part sheet two ends are equipped with aluminium end ring and end plate successively, at the cylindrical wall of end plate and rotor sheet the slot welding seam are arranged axially.
The utility model, aluminium end ring outer are enclosed within 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.Be applicable to the high speed frequency control motor.
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-axle 2-end plate 3-rotor sheet 4-slot welding seam 5-aluminium end ring
Five, embodiment
As shown in drawings, include axle and rotor sheet 3, end plate 2, the aluminium end ring 5 that silicon steel sheet laminates is housed on 1 forms, its 1 upper rotor part sheet 3 two ends of axle are equipped with aluminium end ring 5 and end plate 2 successively, at the cylindrical wall of end plate 2 and rotor sheet 3 slot welding seam 4 are arranged axially.Aluminium end ring 5 outer is enclosed within the tubular position of end plate 2.
The cylindrical of end plate 2 and rotor sheet 3 is processed V-shaped groove, connects in the V-type slot welding and forms slot welding seam 4.Slot welding seam 4 can adopt the 16-90 bar.
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. high strength rotor, include the rotor sheet (3), end plate (2), aluminium end ring (5) composition that silicon steel sheet are housed on axle (1) axle laminate, it is characterized in that axle (1) axle upper rotor part sheet (3) two ends are equipped with aluminium end ring (5) and end plate (2) successively, slot welding seam (4) is axially arranged at the cylindrical wall of end plate (2) and rotor sheet (3).
2. a kind of high strength rotor according to claim 1 is in the outer tubular position that is enclosed within end plate (2) that it is characterized in that aluminium end ring (5).
