Abstract
The utility model relates to an energy-saving electric fan which is an electric fan formed by that the inner holes of special-shaped 16 groove stators are adopted, the inserted wires adopt the speed regulation method that the connecting wires of long span length and the main windings are in series-parallel connection, and the high efficiency fan blades in special geometric shape are matched, etc; the electric fan has the advantages that the motor is saving in material and low in temperature, the working area of blades is completely used, and the inserted wires are convenient; the entire machine consumes little energy, the input power is 42.5 watt-44 watt, and the power factors of the medium speed and the low speed are advancing and capacitive.
Description
Energy-saving electric fan of the present utility model is 300～400 millimeters a electric fan, particularly 400 millimeters electric fan.
The general fan blade that adopts single-phase cover pole type induction motor or single phase capacitor operating type motor configuration mango form propeller shape of known electric fan.Groove on its motor stator generally is pyriform or flat-bottom slot, and groove is symmetrical.The main winding line directly is generally 0.23 millimeter of φ 0.21 or φ, pays a winding wire diameter and be 0.19 millimeter of φ 0.17 or φ, and controllable silicon is generally adopted in speed governing, methods such as auto-transformer or L type, the tap of T type.Shortcomings such as the electric fan that constitutes with above-mentioned parts exists manufacturability bad, and electrode performance is relatively poor, and material consumption is big, and the bottom gear input power is big, and it is big to consume energy.
The purpose of this utility model is to provide a kind of motor and fan blade perfect match for overcoming above-mentioned shortcoming, improves the use value and the overall efficiency of electric fan, reaches the electric fan of energy-saving effect.
Solution of the present utility model is: increase special-shaped 16 groove diameter of stator bores, shorten iron core thickness, 0.14 millimeter of main winding line footpath φ, 0.17 millimeter of the number of turn 725 * 2+725 * 2,1450 * 2 pair winding wire diameter φ, the number of turn 874 * 2; The profile of blade is the efficient fan blade with special geometrical shape, and speed governing adopts the main winding series parallel connection to connect method; The wiring of rule employing long span makes alternate and electrode insulation is strengthened, and makes motor windings and blade coupling.
Adopt the utility model that motor material is economized, temperature rise is low, and blade work done district utilizes fully, and rule is convenient, the complete machine less energy consumption, and the power factor of input power complete machine middling speed and low speed is leading, is capacitive.It is 42.5～44 watts;
The utility model will be illustrated more clearly in from the accompanying drawing of the following example.
The parts assembling schematic representation of Fig. 1 Energy-saving electric fan;
The elementary diagram of Fig. 2 Energy-saving electric fan;
Fig. 3 a is the fan blade front view of Energy-saving electric fan, and b is the side view of fan blade shown in a.
Electric fan is by front mesh enclosure (1), fan blade (2), and rear net cover (3), front cover (4), stator (5), rotor (6), rear end cover (7), rear casing (8), column and base (9) are formed.The profile of stator (5) is a square circular, and stator (5) internal diameter and rotor (6) external diameter strengthen, and the internal diameter of stator (5) is 50.2 millimeters, shortens core length.The flute profile of stator (5) is made special-shaped groove, and special-shaped groove is asymmetric, and facewidth yoke is high to be equated, makes groove area increase uniform electromagnetic field.The main winding line directly is 0.14 millimeter of φ, and 0.17 millimeter of winding wire diameter φ is paid in the number of turn 725 * 2+725 * 2,1450 * 2, the number of turn 874 * 4, and electric fan moves under the magnetic field of circle or sub-circular.Speed governing winding series parallel connection on the stator (5) connects, and rule adopts the long span wiring.The profile of three fan blades (2) has special geometrical shape, and the Weight control of single blades (2) is at 90～95 grams, and disk ratio is 0.54, aspect ratio is 0.77, the established angle of fan blade is 13～14 degree, and camber is 9.5～10.5 millimeters, and radially becoming the camber of 4 degree with the string vertical line is 5 millimeters.
