What Is The Role Of Power Tools Carbon Brush In The Motor?

Oct 11, 2017


1. Add the external current (excitation current) to the rotating rotor (input current) via the Power Tools Carbon Brush Power Tools Carbon Brush
2. Introduce the static charge on the large axis through the Power Tools Carbon Brush (grounded Power Tools Carbon Brush) (output current)
3. Change the direction of the current (in the commutator motor, the brush also plays a commutation role)
4. The large axis (ground) lead to the protection device for the rotor ground protection and measurement of the rotor positive and negative voltage to the ground commutator by the brush and commutation ring composition, Power Tools Carbon Brush is a brush. As the rotor rotation, the brush is always with the commutator ring friction, and in the moment of commutation will produce EDM, so the brush is a DC motor in the wearing parts. In order to improve the life of the DC motor, operating stability and reduce the DC motor noise and electromagnetic interference, brushless DC motor has gradually replaced the trend of brush motor. General AC motor without constant magnetic field, so do not need commutator, it does not need brush; but the size of the AC motor is generally relatively large. Electric motors used in household appliances are generally AC motors, such as fans, washing machines, refrigerators, air conditioners and so no Power Tools Carbon Brush, but there are also using DC motors, such as many electric shavers, kitchen appliances, electric bicycles and so on There are Power Tools Carbon Brush, that is, DC motor (not including brushless) have. The motors that use the dry batteries are DC motors.
According to the use of Power Tools Carbon Brush objects can be divided into: steam turbine generator brush, rolling motor useful brush, traction motor brush, AC motor brush, aircraft motor brush.
one. Maintenance time It is recommended that the key components of the regulator and the Power Tools Carbon Brush be checked and maintained every three months. two. Maintenance method Check whether the Power Tools Carbon Brush is loose, whether the Power Tools Carbon Brush is in the same plane, and whether it is in good contact with the same line, and any condition must be replaced in time. Otherwise, it will affect the normal operation and use of the regulator life. If you find Power Tools Carbon Brush wear too fast, check the column regulator coil is smooth, whether there is a floating point; load current is too large.
Power Tools Carbon Brush To ensure that you can move freely up and down, the gap between the Power Tools Carbon Brush and the inner wall of the brush is between 0.1 and 0.3 mm to avoid excessive power generation between the Power Tools Carbon Brush and the brush swing. Brush the lower edge of the edge from the commutator surface should be kept at about 2 mm. On the same motor, you should use the same type of Power Tools Carbon Brush in principle, but for large and medium-sized motors that are particularly difficult to change, you can use Gemini Power Tools Carbon Brush, which slides into the side with good lubrication, The Power Tools Carbon Brush is improved by the use of Power Tools Carbon Brush, which suppresses sparking power.
To ensure proper operation of the motor, the Power Tools Carbon Brush good performance mark should be:
a in the commutator or collector ring surface can quickly form a layer of uniform, moderate and stable oxide film.
b Power Tools Carbon Brush has a long service life and does not wear commutator or collector rings
c Power Tools Carbon Brush has a good commutation and current collection performance, so that the spark is suppressed within the allowable range, and the energy loss is small.
d Power Tools Carbon Brush running, but hot, low noise, reliable assembly, no damage.
The role of the motor is to change the current direction of the DC motor and AC motor, DC motor is to change the rotor of the conductive coil, thus changing the rotor pole. The collector ring thus changes the movement of the motor. The Power Tools Carbon Brush is a commutator or slip ring for motors that acts as a sliding contact for deriving the incoming current. It is conductive, thermally conductive and lubricated well and has a certain mechanical strength and commutation spark. Power Tools Carbon Brush, Brush Almost all motors use Power Tools Carbon Brush, which is an important part of the motor.
Power Tools Carbon Brush is suitable for all kinds of motors, generators and axles. Has a good commutation performance, long service life. The Power Tools Carbon Brush is a commutator or slip ring for motors that acts as a sliding contact for deriving the incoming current. It is conductive, thermally conductive and lubricated well and has a certain mechanical strength and commutation spark. Almost all motors use Power Tools Carbon Brush, which is an important component of the motor. Widely used in a variety of AC and DC generators, synchronous motors, battery DC motor, crane motor collector ring, all types of welding machines and so on. With the development of science and technology, the type of motor and the use of working conditions more and more diverse, and therefore need to have a variety of different grades of brushes to meet these requirements, so the type of brush with the development of the motor industry more and more.
