Is the single-phase carbon brush motor a direct current motor or an AC motor?
(1) motor is a DC motor with single-phase brushless motor or AC, there is also some DC motor AC and DC motor, such as most of the pistol electric drill AC and DC motor, AC and DC power can also be used to use.(2) the power supply of rectifier bridge is not from positive and negative pole, and the power supply of rectifier bridge must have positive and negative poles, otherwise it is not power supply of rectifier bridge.(3) bidirectional thyristor should be used in AC circuit. If your motor speed is bidirectional thyristor, it may be AC and DC motor.DC motor carbon brush and AC motor carbon brush is the same, so there are AC and DC dual series motor.
The motor carbon brush is suitable for all kinds of motors, generators, wheel machines. The utility model has better commutation performance and long service life. Is the motor carbon brush for motor commutator or slip ring, as sliding contact body import and export current, its thermal conductivity, and good lubrication performance, and has certain mechanical strength and direction of the spark of instinct. Almost all motors use carbon brush, which is an important component of the motor. Widely used in all kinds of AC and DC generator, synchronous motor, battery DC motor, crane motor, collector ring, all types of welding machine, and so on. With the development of science and technology, more and more types and working condition of the use of the motor is more diverse, so need to have different grades of brush to meet these requirements, it is also with the brush type motor industry development more and more.
The role of the motor is to change the current direction of the DC motor and AC motor, the DC motor is to change the rotor's conductive coil, thereby changing the rotor magnetic pole. Thereby changing the motion of the motor. The carbon brush is used for motor commutator or slip ring, as sliding contact body import and export current, its thermal conductivity, and good lubrication performance, and has certain mechanical strength and direction of the spark of instinct. Almost all motors use carbon brush, which is an important component of the motor.
