Q:Is the permanent magnet motor a direct current motor or an AC motor?
Permanent magnet motor is DC motor, AC motor can also be (such as household; similarly, no breeze ceiling fan) can be a permanent magnet DC motor, AC motor can also be, even AC / dc.
Q:Can AC motors be controlled by frequency converter?
Only frequency conversion motor can use frequency converter to speed up, ordinary motor can not use frequency converter speed regulation.But it is possible to start the AC motor by using frequency converter.
Q:Why asynchronous motor AC excitation, rather than DC excitation?
Synchronous motor is also a kind of AC motor. Mainly used for generators, motors can also be used, generally used for larger power, speed does not require the adjustment of production machinery, such as large water pumps, air compressors and mine fans. In recent years, due to the development of permanent magnet materials and electronic technology, micro synchronous motor has been more and more widely used. One of the characteristics of synchronous motors is the steady running speed, N and stator current frequency f1 has a strict constant relationship, that is, n=60f1/p=n0 synchronous motor speed n and rotating magnetic field speed N0 the same. The name of "synchronization" comes from here. The stator of a synchronous motor goes without saying that the general rotor coil must be energized to keep it in sync with the stator. (the rotor of the micro synchronous motor can be made of permanent magnetic steel.)Asynchronous motor is different, the stator winding energized to generate rotating magnetic field, in the rotor to generate induction current, so that the motor rotation. Structure than synchronous motor simple
Q:Does the AC motor have carbon brushes?
Its electrical conductivity, thermal conductivity and lubrication are good, and have a certain mechanical strength and reversing spark instinct. Almost all motors use carbon brush, which is an important component of the motor.
Q:Structure of alternating current motor
An alternating current motor is mainly composed of an electromagnet winding or a distributed stator winding and a rotating armature or rotor for generating a magnetic field. The motor is made by the rotation of the energized coil in the magnetic field.
Q:Why is an AC motor more popular than a direct current motor? System description, thank you.
The reason of AC motor is common and convenient power supply: power generator and transformer, transmission and distribution in the form of communication, AC power supply, the utility grid can be directly used for AC motor is simple and convenient; DC motor to be alternating to direct before use, trouble.2, AC motor especially the induction motor, has the advantages of simple structure, easy manufacture, convenient installation, reliable use, low cost, high efficiency; and the DC motor is complicated in structure, manufacture and installation of trouble, use is not reliable, high cost, low efficiency.
Q:What's the difference between a three-phase AC motor and a DC motor?
Squirrel cage type AC motors are of small size, light weight, low price and long service life, which are opposite to the direct current motors;But the DC motor speed performance is good, AC motor is a little bit worse.
Q:What is the difference between AC variable frequency speed control and DC variable frequency speed regulation?
AC variable speed DC speed is widely used because the ratio of AC motor, not the principle of frequency conversion has the advantage of frequency control can only be applied to control, and the torque is unable to achieve precise control, the reason is very simple, the DC motor armature and field is coupled, are separated, such of armature current and exciting current to achieve accurate control. The AC speed control, armature current and exciting current is coupled, is unable to achieve precise control, although the frequency current vector control, which is based on the modern control theory, through the vector transformation, the armature current and exciting current coupling in AC motor solutions, in order to control, which is the principle of simulation DC speed regulation. But it is difficult to control the DC speed. Therefore, in the rolling mills, paper and other requirements of the high torque industry, DC speed control is still widespread. And only for speed control, at present, variable frequency speed regulation can be realistic DC speed control characteristics, because the advantages of AC motor is DC motor can not do.
Q:Why is DC motor speed regulating better than AC?
The magnetic field of an AC motor is strongly coupled and time-varying, while the external conditions change and the speed changes as well, and it changes.
Q:Is the single-phase carbon brush motor a direct current motor or an AC 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.
