Description
Technical field
The utility model relates to the punching of a kind of single phase series motivated motor rotor.
Background technology
Series-wound motor is meant that stator excitation winding and armature (rotor) winding are series connection, but not only can perfectly straight stream but also indirect current, has the motor of commutator switching-over.
Series-wound motor mainly is by stator, rotor, and forward and backward end cap (cover) and heat radiation fan blade are formed. and stator is made up of stator core and the winding that is enclosed within on the pole shoe, and its effect is to produce magnetic flux, cover before and after magnetic conduction and the support; Rotor is by rotor core, axle, and armature winding and commutator are formed, and its effect is to guarantee and produce continuous electromagnetic torque, through the acting of rotating shaft drive load, electric energy is converted into mechanical energy; The support armature has been covered in front and back, and stator and rotor are linked fixedly all-in-one-piece effect. and its shaft, forward and backward cover will have enough intensity, in case armature and cover generation covibration cause vibration and dangerous. and have in the general forward and backward cover and roll or sliding bearing.
Though present stage single phase series motivated motor have light, volume is little, be easy to carry about with one, be easy to advantage such as use, because the less employed power of motor of volume generally all below 850W, is difficult to satisfy the high-intensity productive labor of people.
The utility model content
The utility model technical problem to be solved is to provide a kind of compact conformation, and stock utilization is high, the single phase series motivated motor rotor punching that motor performance significantly improves.
The technical scheme of the utility model is: the punching of a kind of single phase series motivated motor rotor; Comprise stator punching and rotor punching; Described stator punching comprises pole body part and yoke part; The pole shoe arc length of said pole body part is 37～39mm, and the stator yoke height of yoke part is 3.8～4.2mm, and the magnet pole widths of pole body part is 19～21mm.
The pole shoe arc length of the utility model is very important.If the pole shoe arc length increases, the magnetic pole area is just big, just can produce more magnetic flux; Make rotor produce bigger torque, thereby can drive bigger load, but the pole shoe arc length can be brought following two shortcomings after increasing: the one: the pole shoe arc length increases; The pole tip distance of two adjacent poles just shortens, and the magnetic resistance of pole tip leakage flux just diminishes, and the pole tip leakage flux just increases; Therefore, from reducing the angle of leakage flux, we do not hope that the pole shoe arc length is too big.The 2nd: the pole shoe arc length is too big, and switching-over is worsened, and spark increases, and reason is the increase of armature reaction electromotive force.
Preferably, said stator punching is provided with 4 wire casings, and each wire casing area is 58.5 square millimeters.
Preferably, said rotor punching is provided with 12 wire casings, and each wire casing area is 32.44 square millimeters.
Preferably, said pole body partly comprises pole shoe and pole tip, the straightway in the pole tip outside and the pole shoe arc is tangent and from the horizontal by 50 ° of angles.
Preferably, the internal diameter of said stator punching is 34～36mm, and the external diameter of stator punching is 55～57mm, and the external diameter of rotor punching is 33～35mm.
Preferably, said rotor punching is
0.60～0.62 with the ratio of the external diameter of stator punching.
Preferably, the outline of said stator punching is cut flat structure for the four sides.
The beneficial effect of the utility model is:
1. designed best pole shoe arc length, on the basis that guarantees big pole shoe arc length, fully taken into account the distance between adjacent pole, two pole pitch are not reduced, kept trying one's best big groove area, balanced tooth portion width and yoke portion width guarantee machine performance;
2. the rotor punching of the utility model has increased the effective area of coil groove, makes and can hold more enamelled wire, obtains high-power requirement more easily, arrives the purpose of energy-conservation joint consumption;
The stator punching of the utility model adopt the top rake pole motor (be the straight line in the pole tip outside and the pole shoe arc is tangent and from the horizontal by 50 ° of angles); Effectively raise the serious distortion of system air-gap field; Reduce near the magnetic flux density in pole tip zone, improved switching-over, improved motor performance;
4. the utility model stator punching has fully taken into account cutting out property of economy, and outline is cut flat structure for the four sides, and the leftover pieces under remaining when the punching of punching out series excited machine are minimum, and the utilance of silicon steel sheet is the highest.
