Washing Machine Carbon Brushes Running In The Common Phenomenon

Washing Machine Carbon Brushes running in the common phenomenon
Due to the resistance is too large or uneven dispersion of the birth of the fever: the collection ring and the Washing Machine Carbon Brushes is to decide to slide each other to run the excitation current, according to the capacity and model differences, each collection ring about the number of scattered Ten Washing Machine Carbon Brushes, due to the difference between the resistance of the resistance, the current distribution of the difference will lead to fever is not symmetrical, there are several reasons:
(1) Washing Machine Carbon Brushes and slip ring appearance to fight resistance, Washing Machine Carbon Brushes and brush braids to fight resistance, brush braids and brush frame lead to fight too much resistance. Can measure a single Washing Machine Carbon Brushes total pressure drop, Washing Machine Carbon Brushes to fight the pressure drop, brush body pressure drop, the connection pressure drop, brushing the pressure drop held between each other recently checked. Also check whether the screws in the circuit are tightened. Check the Washing Machine Carbon Brushes to fight the surface of the clean level, whether there is oil pollution.
(2) Washing Machine Carbon Brushes pressure is not uniform or do not meet the requirements, probably have a Washing Machine Carbon Brushes is too short, the spring due to overheating soft aging loss of flexibility and so on. Should use the spring scale to check the Washing Machine Carbon Brushes pressure. Constant pressure spring should be complete without machine damage, the pressure should be consistent with the delineation of its products, the uniform pole of the spring pressure problems should not exceed 5%; non-constant pressure Washing Machine Carbon Brushes spring, the pressure should be specified when the product Set, when no delineation, should be adjusted to the washing machine does not make the minimum pressure of carbon brush fire, as usual 140-250g / cm2, unified brush on each Washing Machine Carbon Brushes pressure should be symmetrical.
(3) the collector ring and rotor lead wire resistance is too large, this situation should be between the collector ring and the rotor between the fastening screws to strengthen.
(4) Washing Machine Carbon Brushes material is poor, poor conductivity, the use of models do not meet the requirements of the use of the difference between the type of Washing Machine Carbon Brushes. Uniform motor should be used on the unified model, uniform factory Washing Machine Carbon Brushes, stall appearance check there are significant differences in the Washing Machine Carbon Brushes should be replaced.
 Washing Machine Carbon Brushes is the role of the relative movement of the two objects connected between the current. The most common is the motor commutator, there are linear motion tram, electric locomotive Washing Machine Carbon Brushes. Washing Machine Carbon Brushes different shapes, the use of the motor for the rectangle, placed in the Washing Machine Carbon Brushes holder. Washing Machine Carbon Brushes and commutator or slip ring between a certain pressure, large-scale Washing Machine Carbon Brushes structure is more complex, small Washing Machine Carbon Brushes is relatively simple.
    Washing Machine Carbon Brushes current is not the same, large-scale Washing Machine Carbon Brushes on the wire, small often led by the elastic conductive film. Washing Machine Carbon Brushes materials are mostly made of graphite, in order to increase the conductivity, there are made of copper-containing graphite, graphite has a good electrical conductivity, soft texture and wear. Lifting crane and subway, subway with the collection of boots, can also be attributed to the Washing Machine Carbon Brushes, but the material and structure and graphite Washing Machine Carbon Brushes is very different.
 Washing Machine Carbon Brushes is made of graphite, in order to increase the conductivity, there are made of copper-containing graphite, graphite has a good electrical conductivity, soft texture and wear. Washing Machine Carbon Brushes can be used for DC motor or AC commutator motor, such as general power tools, hand drill and angle grinder, are used to it. Washing Machine Carbon Brushes is used and commutator to achieve the motor current commutation,
    Washing Machine Carbon Brushes is a sliding contact of a motor (except a squirrel-cage motor) conducting current. In the DC motor, the Washing Machine Carbon Brushes also charged with the armature winding induction alternating electromotive force, commutation (rectification) task. Practice has proved that: the reliability of motor operation, to a large extent determined by the performance of the Washing Machine Carbon Brushes.
