Abstract
The utility model discloses a rotor punching sheet of an air conditioner fan motor. A hollow inner round hole is arranged at the middle of the rotor punching sheet; multiple punching sheet grooves radially arranged along the rotor punching sheet are uniformly distributed between the outer circle of the rotor punching sheet and the hollow inner round hole; the diameter of the outer circle of the rotor punching sheet is 72-80mm, and the diameter of the hollow inner round hole is 12-17mm; the punching sheet groove is of an inverted pear-shaped structure; and the groove opening width C is 0.7-0.9mm, the groove shoulder width D is 2-3mm, the groove depth F is 2-4mm, and the groove bottom radius R is 1.5-2mm. Compared with the traditional rotor punching sheet, the rotor punching sheet disclosed by the utility model has the following advantages: 1, the punching sheet groove is of an inverted pear-shaped structure, so that the rotor cast aluminum quality is improved, simultaneously the skin effect of the rotor is increased, the motor torque is smoother, and the vibration and noise of the motor are reduced; 2, the distribution of the magnetic density of the tooth part of the motor rotor is more reasonable, and the collocation of the rotor and stator punching sheets is more reasonable; and 3, the use of raw materials of a winding and an iron core is reduced.
Description
Technical field
The utility model relates to the rotor punching of a kind of rotor punching of motor, particularly a kind of fan motor of air conditioner, belongs to the improvement technology of the rotor punching of fan motor of air conditioner.
Background technology
The rotor punching of tradition fan motor of air conditioner generally adopts the peariform slot structure, and the rotor bottom size is less, and cast aluminium is second-rate; For motor operation, during startup torque less, need on design, remedy, motor performance is relatively poor thus, cost is higher, simultaneously, has also caused motor oscillating, noise bigger.Therefore, be necessary to do further improvement.
The utility model content
The purpose of the utility model aims to provide that a kind of to improve motor magnetic close; Improve the casting aluminum rotor quality, have the dependence kelvin effect, increase torque when starting automatically; The rotor punching of the fan motor of air conditioner of the function of rotor resistance loss when reducing operation is to overcome weak point of the prior art.
Press the rotor punching of a kind of fan motor of air conditioner of this purpose design; Circular hole in the hollow has been made at the middle part of rotor punching; Be evenly distributed with the some punching grooves that are provided with along the radial direction of rotor punching in rotor punching cylindrical and the hollow between the circular hole; Its architectural feature is that the outside diameter
of rotor punching is 72～80mm; The diameter
of circular hole is 8.05～17mm in the hollow; The punching groove adopts the structure of falling the pyriform, and slot opening C is 0.7～0.9mm, and groove shoulder breadth D is 2～3mm; Groove depth F is 2～4mm, and bottom radius R is 1.5～2mm.
Said punching groove is arranged on the outer inner round side of rotor punching.
Said punching groove is provided with 33,34 or 36.
The utility model is compared with the conventional rotors punching and had following advantage: 1. the punching groove adopts the structure of falling the pyriform, has improved the casting aluminum rotor quality, has increased the kelvin effect of rotor simultaneously, and motor torque is more level and smooth, has reduced the vibration and the noise of motor; 2. make the close distribution of motor rotor tooth portion magnetic more reasonable, rotor and the close collocation of stator punching magnetic are more reasonable; 3. reduced the raw material consumption of winding and iron core.
Description of drawings
Fig. 1 is the utility model one example structure sketch map.
Fig. 2 is the partial enlarged drawing at I place among Fig. 1.
Among the figure: 1 is rotor punching, and 2 are the punching groove, and 3 is circular hole in the hollow, and C is a slot opening, and D is the groove shoulder breadth, and F is a groove depth, and R is a bottom radius.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
1. referring to Fig. 1-Fig. 2, circular hole 3 in the hollow has been made at the middle part of rotor punching 1, is evenly distributed with the some punching grooves 2 that are provided with along the radial direction of rotor punching 1 in rotor punching 1 cylindrical and the hollow between the circular hole 3, and punching groove 2 is arranged on rotor punching 1 outer inner round side.Wherein the outside diameter of rotor punching 1
is 76mm; The diameter
of circular hole 3 is 12mm in the hollow; Punching groove 3 adopts the structure of falling the pyriform; Slot opening C is 0.8mm; Groove shoulder breadth D is 2mm; Groove depth F is 2.5mm, and bottom radius R is 1.8mm, and present embodiment punching groove 2 is set at 33.
