Abstract
The utility model relates to a rotator for an asynchronous motor and is mainly used for an open-type asynchronous squirrel cage motor. End rings are respectively arranged on the two ends of the body of the utility model, fan blades bulging axially are arranged on and integrated with the end face of each end ring, and the diameter of a circumference formed by the fan blades is smaller than that of the excircle of each end ring. By adjusting the diameter of the circumference formed by the fan blades and the excircle diameter of each end ring, reasonable adjustment of blast pressure and volume is realized, thereby improving the ventilation efficiency of the fan, and simultaneously improving the utilization rate of materials of the motor and reducing the cost of the motor.
Description
Technical field
The utility model relates to asynchronous motor, especially relates to the rotor of asynchronous motor.
Background technology
The asynchronous interconnected cage motor of existing open type, the particularly asynchronous interconnected cage motor of cast iron structure open type adopt the cast-aluminum rotor flabellum as ventilation components usually.The diameter of the periphery that the flabellum lateral surface of two ends of rotor axial projections is constituted equates normally that with the diameter of end ring cylindrical this version has limited the adjusting to blast and air quantity to a great extent, is unfavorable for the raising of ventilation fan efficient.
The utility model content
The utility model has limited adjusting to blast and air quantity at above-mentioned prior art, is unfavorable for improving the technical problem of ventilation fan efficient, provides a kind of and can rationally regulate blast and air quantity, can improve the rotor of the asynchronous motor of ventilation fan efficient.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of rotor of asynchronous motor, the two ends of rotor body have end ring respectively, the flabellum that one with it and axial projections are arranged respectively on the end face of end ring, the flabellum that it is characterized in that described axial projections is radial distribution, and the diameter of the periphery that each flabellum lateral surface is constituted is less than the outside diameter of described end ring.
The utility model also comprises following technical characterictic: described flabellum is the plane flabellum.
Technique effect of the present utility model is:
1, the diameter that can be by regulating the periphery that each flabellum lateral surface constituted and the outside diameter of end ring are realized the reasonable adjusting to blast and air quantity, thereby are improved the drafting efficiency of fan.
2, reduce the use of material, improved the stock utilization of motor, reduced the cost of motor.
Description of drawings
Fig. 1 is a half sectional view of the present utility model
Fig. 2 is a left view of the present utility model
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As Fig. 1, shown in Figure 2, the two ends of the rotor body 1 of asynchronous motor have end ring 2 respectively, a plurality of flabellums 3 that one with it and axial projections are arranged respectively on the end face of end ring 2,12 flabellums 3 are arranged in the present embodiment, the flabellum 3 of axial projections is radial distribution, the diameter of the periphery that each flabellum 3 lateral surface is constituted is less than the outside diameter of described end ring 2, both ratios design the requirement of ventilating according to the power of motor size, the diameter of the periphery that each flabellum 3 lateral surface is constituted is set in a rational value, thereby blast and air quantity are adjusted in a reasonable range, to improve the drafting efficiency of fan, improve the stock utilization of motor simultaneously, reduced the cost of motor.Flabellum 3 among Fig. 1, Fig. 2 is plane flabellums, and it is the plane in two sides radially.
As can see from Figure 1, the periphery that the excircle of end ring 2 and each flabellum lateral surface are constituted has gradient respectively, and this gradient is the needs of manufacturing process.
Claims (2)
1. the rotor of an asynchronous motor, the two ends of rotor body have end ring respectively, the flabellum that one with it and axial projections are arranged respectively on the end face of end ring, it is characterized in that: the flabellum of described axial projections is radial distribution, and the diameter of the periphery that each flabellum lateral surface is constituted is less than the outside diameter of described end ring.
2. according to the rotor of the described a kind of asynchronous motor of claim 1, it is characterized in that: described flabellum is the plane flabellum.
