To regularly replace the Washing Machine Carbon Brushes is for what?
    To regularly replace the Washing Machine Carbon Brushes is for what? For a variety of models of large motor units, if the shutdown due to the replacement of Washing Machine Carbon Brusheses affect the normal production, we under normal circumstances can be recommended to replace each 20% of the Washing Machine Carbon Brushes, that is, each motor 20% of the rod, so the replacement of the time, about 1 to 2 weeks each time interval, and so on after the gradual run and then the rest of the Washing Machine Carbon Brushes replacement work, so you can ensure that the motor can be a normal continuous operation.
     In the same motor above, in the replacement of the Washing Machine Carbon Brushes, you should try to use the same type of Washing Machine Carbon Brushes, but for the individual for the special difficulties of large and medium-sized motor, you can also use the twin wash machine carbon brush, because the twin Washing Machine Carbon Brushes Of the sliding edge of the lubrication performance is still relatively good, so slide out once the use of can inhibit the spark of the Washing Machine Carbon Brushes, you can make the Washing Machine Carbon Brushes to improve the operation.
    Because it is not a one-time all the replacement, the degree of friction is not the same, so we have to regularly replace the Washing Machine Carbon Brushes to ensure the normal operation of the motor.
Washing Machine Carbon Brushes large shaft ground and rotor ground: DC motor is set by the commutator (commutator) and the Washing Machine Carbon Brushes on the rotor shaft end! AC motor is made by the slip ring and the Washing Machine Carbon Brushes To complete
 "Big shaft grounding" and "rotor ground" these two concepts of the so-called large shaft grounding refers to the entire rotor "metal surface" can not have static charge accumulation, too much static charge accumulation will cause the ground potential rise, which will Rotor bearing lubricating oil film breakdown to make the loss of lubrication, and then the rotor journal and bearing bearing a direct friction, so we have to rotor the metal surface and the earth connected to the cumulative release of the static charge.
  Rotor grounding refers to the rotor inside the electrical winding wire rod grounding, which is not allowed, because the rotor's internal winding circuit is DC, in the case of good insulation, winding positive and negative poles on the ground voltage distribution, when the A little ground, it will cause the other ground is not grounded to the full voltage, this time it is easy to ground a pole insulation breakdown, so a little ground fault will quickly develop into two points after the ground, so we To set a little ground protection, when a little grounding occurs when the alarm or vote in the trip to start the generator run.
Washing Machine Carbon Brushes in the running of the current fault How to determine you can use the clamp ammeter card about the Washing Machine Carbon Brushes current. If the current is normal, it is the quality of the Washing Machine Carbon Brushes problems, or slip ring with a groove, not flat. There are Washing Machine Carbon Brushes current fault has the following situation: 1. Turn between the short circuit, resulting in spark 2. Washing Machine Carbon Brushes Compression Spring Pressure Sparks Big 3. Commutator Mica Deformation Causes Connection of Enameled Wire Breaks - Causes Sparks.
   Washing Machine Carbon Brushes and commutator in the motor rotation will produce sparks, toner in addition to the components will cause damage, the use of occasions are also limited. AC motor without Washing Machine Carbon Brushes and commutator, maintenance-free, strong, wide application, but the characteristics of the DC motor to achieve the equivalent of the performance of complex control technology to be used to achieve. Now the rapid development of semiconductor power components to switch the frequency of many, to enhance the performance of the drive motor. Microprocessor speed is faster and faster, can be achieved AC motor control placed in a rotating two-axis orthogonal coordinate system, the appropriate control AC motor in the two-axis current component, to achieve similar DC motor control and DC motor with the equivalent performance.
    Washing Machine Carbon Brushes and brush grip should be a certain gap. If the gap is too small, due to thermal expansion may cause the Washing Machine Carbon Brushes in the brush grip stuck. Washing Machine Carbon Brushes in the brush grip stuck or floating up and down is not flexible, will affect the Washing Machine Carbon Brushes and slip ring contact. But the gap can not be too large, otherwise the Washing Machine Carbon Brushes in the brush grip easy to beat. In addition, the brush is clearly fixed by the packing method, the law of riveting or molding method, so if the Washing Machine Carbon Brushes in the brush grip card too dead, the operating staff if the force is not appropriate, it is likely to pull out the brush, and Washing Machine Carbon Brushes in the brush grip. So choose the type of system 1 Washing Machine Carbon Brushes at the same time, but also the size of the Washing Machine Carbon Brushes to the size of the washing machine to brush the brush can be free to pull the brush as well.
