Chinese patent literature CN 201315506Y discloses a kind of rotor punching for fan motor of air conditioner on September 23rd, 2009, circular hole in the hollow has been made at the middle part of rotor punching, be evenly distributed with the some punching grooves that arrange along the radial direction of rotor punching in rotor punching cylindrical and the hollow between the circular hole, the outside diameter φ A of rotor punching is 61～63mm, the diameter phi B of circular hole is 8.05～15mm in the hollow, slot opening C is 0.7～0.9mm, groove shoulder breadth D is 3.94～4.14mm, groove shoulder height E is 0.65～0.85mm, groove depth F is 7.4～7.6mm, and bottom radius R is 1.0-～1.2mm.
The utility model content
The purpose of this utility model aim to provide a kind of simple and reasonable, improve motor magnetic close, improve casting aluminum rotor quality, the vibration of motor and the rotor punching of the fan motor of air conditioner that noise is little, cost of manufacture is low, 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, the middle part of rotor punching is provided with circular hole in the hollow, be evenly equipped with the some punching grooves that radially arrange along rotor punching in the cylindrical of rotor punching and the hollow between the circular hole, its architectural feature is that the outside diameter φ A of rotor punching is 60～66mm, the diameter phi B of circular hole is 7～12mm in the hollow, the slot opening C of punching groove is 0.45～0.85mm, the high E of the notch of punching groove is 0.4～0.8mm, the groove shoulder breadth D of punching groove is 3.2～3.8mm, the groove shoulder height F of punching groove is 0.4～0.6mm, the groove depth G of punching groove is 6.5～10mm, and the bottom radius R of punching groove is 0.5～1.1mm.
Described punching groove is along the outer inner round side that circumferentially is distributed on rotor punching.
Described punching groove is the structure of falling the pyriform.
The number of described punching groove is 26 or 34.
The utility model makes the close distribution of motor rotor tooth section magnetic more reasonable after adopting above-mentioned technical scheme, and rotor and the close collocation of stator punching magnetic are more reasonable; And reduced the raw material consumption of winding and iron core, reduced cost of manufacture.
Punching groove in the utility model adopts the structure of falling the pyriform, has improved the casting aluminum rotor quality, has increased simultaneously the kelvin effect of rotor, and motor torque is more level and smooth, has reduced vibration and the noise of motor; Rely on kelvin effect, automatically increase torque when starting, rotor resistance loss when reducing operation.
The utlity model has simple and reasonable, improve motor magnetic close, improve casting aluminum rotor quality, the vibration of motor and the characteristics that noise is little, cost of manufacture is low.
