Description
Technical field
The present invention relates to the stator punching of the stator punching of motor, particularly a kind of single phase capacitor operating type motor, mainly as the stator punching of air conditioner fan motor, belong to the high energy efficiency stator punching designing technique that high-power indoor split-type air conditioner motor is used.
Background technology
It is Φ 92mm that traditional family expenses split-type air conditioner is moulded shell motor external diameter specification with single phase capacitor operating type.Its internal stator punching external diameter is Φ 78mm, as shown in Figure 1.When this traditional stator is used for designing high-power indoor split-type air conditioner fan electromotor, have following shortcoming: 1, winding is directly around the stator forehead, and electric efficiency is general all about 40%, and efficient is lower; Relatively the big gearing part width is less because of grooved simultaneously, and motor tooth section magnetic is close too high, and the winding effective rate of utilization is low, and electric efficiency can not improve again.2, power output is designed into 30W under the general rated point rotating speed, can not meet the demands aspect efficient and the temperature rise.3, keeping the motor entire outer diameter is under the constant prerequisite of 92mm so that electric efficiency rise to 50%-55% and more than, power output is designed into 30W-45W and can't realizes under the rated point rotating speed.
Summary of the invention
The stator punching that the object of the invention is to consider the problems referred to above and a kind of single phase capacitor operating type motor is provided, can be in the situation that keep plastic shell motor external diameter Φ 92mm constant, so that the air conditioning indoor machine motor improved efficiency to 50%-55% and more than, simultaneously the output power of motor maximum can reach about 45W under rated speed point working order, with solve present existing structure punching maximum can only be designed into about 30W and efficient in the problem of 40-45%.Particularly suitable of the present invention is made existing family expenses indoor split-type air conditioner and is Φ 92mm with the plastic shell motor external diameter, and rated point requires power output at 30W-45W, and the motor efficiency requires the motor at 50%-55% simultaneously.
The technical scheme that realizes the object of the invention is:
A kind of stator punching of single phase capacitor operating type motor, comprise stator punching, the stator punching center is provided with circular hole in the hollow, radially be provided with some slot for windings along stator punching, form stator tooth between the adjacent slot for winding, the end of stator tooth forms salient pole, and described salient pole evenly distributes at the edge of circular hole in the hollow, it is characterized in that, the size of described stator punching is as follows:
The diameter of stator punching cylindrical: 88.00～88.03mm; The diameter of circular hole: 50.00～50.046mm in the hollow; Stator tooth is parallel teeth, and its width is: 4.9～5.1mm, tooth depth: 6.85～6.95mm;
Winding width of rebate: 1.80～1.85mm, notch is high: 0.48～0.52mm, groove shoulder height: 0.75～0.85mm, bottom land place circular diameter: 66.30～66.50 mm.
Relatively be provided with two side cuts on the said stator punching cylindrical.
Above-mentioned two every side cuts of cutting edge are 1mm, and the distance between two side cuts is: 85.5～86.5mm.
Above-mentioned slot for winding is designed with 16.
The invention has the beneficial effects as follows, owing to having adopted brand-new internal diameter, external diameter and grooved size design, the fully close distribution of each several part magnetic in the coupling magnetic circuit, be optimized design, obtain optimum stator punching inside/outside diameter size collocation and grooved size, so that the motor efficiency improves 5%～10%.Simultaneously the consumption contrast equal-wattage grade motor demand of enamelled wire and steel is lacked 7%～10%.The simultaneously side cut of two 1mm of distribution on the external diameter, comprehensively promoted the utilance of material, reduce simultaneously groove shoulder place size, made things convenient for automated production, and volume and the weight reduction of stator have been reduced, reduce the motor flux leakage impact, reduced rolled steel dosage when further having promoted electric efficiency.The present invention is that a kind of design is ingenious, function admirable, machine motor stamping in the convenient applicable high-power split-type air conditioner.
