Abstract
The utility model relates to an explosion-proof single-phase double-value capacitor asynchronous motor. The utility model comprises a housing, end covers, a stator coil, a rotor coil, a motor shaft which penetrates through the rotor coil, a centrifugal switch which is arranged on a rotary shaft, a bearing and a fan, and the utility model also comprises a starting capacitor, a running capacitor and wire outlets; the utility model adopts the steel plate type housing which combines with the front end cover and the back end cover which are cast with aluminium, the starting capacitor and the running capacitor are arranged on the front end cover of one side, the centrifugal switch is arranged on the same side with the capacitors, and the end covers are provided with the wire outlets. The utility model has the advantages of small size, light weight, compact structure and convenient operation.
Description
The utility model is a kind of motor, the flame-proof type monopole asynchronous motor of locating to use especially for filling station etc.
Present widely used flame-proof type monopole asynchronous motor all adopts cast iron housing and end cap, also will be provided with terminal box and electric capacity box in the motor outside, so its volume is big, weight is big, and structure is not compact, and it is big to take up space, and has influenced its use.
The purpose of this utility model provides the single-phase double value capacitor asynchronous motor of a kind of novel flame-proof type, and its volume is little, in light weight, compact conformation, easy to use.
The purpose of this utility model be achieved in that it comprise casing, end cap, stator coil, rotor coil, pass rotor coil motor shaft, be loaded on centrifugal switch, bearing and fan in the rotating shaft, start electric capacity and running electric capacity, line outlet in addition, it is characterized in that: starting capacitance and running electric capacity are installed in motor one side end cap, the contact switch partial fixing of centrifugal switch with electric capacity with side end cap in, also be provided with line outlet on the end cap.
Adopt the steel plate type casing to use bolt in conjunction with the cast aluminium front and rear cover.
The appearance value proportioning of starting capacitance and running electric capacity is:
Starting capacitance 150 μ F ± 20 μ F, 200 ± 30V;
Running electric capacity 8 μ F ± 2 μ F, 390 ± 30V.
The line outlet place is provided with the rotatable line outlet cap that changes outlet direction.
Can change the direction of Motor Shaft end as required, the corresponding change of blower fan and fan shroud position.
The utility model has the advantages that:, weight is alleviated greatly owing to adopt the structure of outer cover of steel plate and Aluminum Alloy Cover combination; Owing to selected the appearance value proportioning of best starting capacitance and running electric capacity, the appearance value of running electric capacity is reduced greatly than prior art, so the volume-diminished of electric capacity, just might be installed in the end cap, make the electric capacity box be gone to disappear; Because electric capacity is provided with line outlet in end cap and on end cap, go the terminal box that disappeared, therefore the whole volume of motor is dwindled greatly; Particularly be positioned at homonymy because of centrifugal switch and two electric capacity, structure is compact more; Also have rotating outlet flap on the line outlet of end cap, outlet direction can be changed as required; Be not subjected to other element limits owing to go out axle head motor shaft footpath, therefore can increase as required, reduce; Go out also front and back transposition as required of axle head, use very convenient.
Details of the present utility model provides according to following examples and accompanying drawing thereof:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 1.
Fig. 4 is the B-B cutaway view of Fig. 3.
With reference to the accompanying drawings, the utility model comprises casing 5, and it is that steel plate is made, and front end housing 2 and rear end cap 9 all are that cast aluminium is made, front end housing 2 is flat, rear end cap 9 projectioies, the empty thorax of inner formation is combined into one casing 5 and front end housing 2 and rear end cap 9 with bolt 4, front and back ends covers bearing 3 or 2 is housed, motor shaft 1 is installed in the two bearings, and rotor coil 7 is housed on motor shaft 1, is with stator coil 6 outward.At the postmedian of motor shaft 1, near the electric capacity place centrifugal switch 8 is arranged, it is installed on the motor shaft 1 routinely, and fan 13 is contained in the follower head of motor shaft 1, pins with clamp ring 14, and fan guard 15 protections are arranged, and it is fixed on the rear end cap.
Particularly in rear end cap 9, use electric capacity clip 18 fixedly starting capacitance and running electric capacity 10.Motor rear end covers the line outlet 11 that also is provided with projection, and outlet is clamped with wire clip 17, draws casing 5 from line outlet 11, and this line outlet 11 is provided with the line outlet cap 19 that connects with screw, and it can rotate around screw, and outlet direction is changed on demand.16 is interior ground connection among the figure.
The axle head of drawing of the present utility model can change as required, and corresponding blower fan and fan shroud also change thereupon.
The utility model starts electric capacity and running electric capacity also can place two front and rear covers respectively.
The utility model is through the trial-production proof, and its every performance index all are up to state standards, and its volume is little than like product, and weight only is 2/3rds of product of the same type.
