Q:The ac motor doesn't have a brush so how does the rotor rotate?: If you remove the core, you will see something like a coil, usually made of easily conductive metals such as copper or aluminum. Because ac power is a three-phase alternating current of the sine wave, a rotating field is formed on the coils, so there is less of a dc motor.

Q:Why is it that high speed motors rarely communicate?: High-speed motor power is small, the production of dc easy, power gain, ac motor are rarely of more than 1500 turns, the high speed rotor of the centrifugal force is too large, high power motor generally do not need such a high speed. Series electric motor can be used for both the dc and dc, high speed, at home food processing machine, handgun drill and so on If you use a converter, you can do special high-speed motors, and the price of the converter is much higher than the motor.

Q:Why does dc motor reduce the voltage regulating ac motor?: The rotational speed of the ac motor is determined by the rotational speed of the rotating field, while the rotational speed of the rotating field is only related to the frequency and the magnetic poles. The frequency is fixed, and the magnetic poles are determined by the structure of the motor, which cannot be changed in the course of operation, so it is quite difficult to adjust the speed of the ac motor. The variable speed of dc motor can be obtained from the hardness of its mechanical properties, which is the relationship between the torque of the motor and the rotational speed. Beta = dM/dn. Type in the beta is hardness, it is the differential ratio of torque and rotational speed, beta is hard characteristics, on the other hand is soft features, need speed can be as long as the soft characteristics of dc motor, series motor, when the load increases, its speed will come down.

Q:What will be the result of the power supply to ac motor after the rectifier (not filtering)?: The ac motor will not be able to transfer the pulse direct current, the light is hot.

Q:Is a single-phase carbon brush motor a dc motor or ac motor?: Phase with a carbon brush motor is dc motor or ac motor, have a plenty of dc motor also have a plenty of ac/dc motor, such as the pistol electric drill majority is ac/dc motors, alternating current (ac) can also be used, direct current (dc) can also be used. (2) (the power supply of the rectifier bridge is not output from the positive and negative terminal.) there must be a positive negative electrode for the power supply of the rectifier bridge, otherwise it is not the power supply of the rectifier bridge. (3) the bidirectional thyristor is applied to alternating current circuit, and if your motor speed is a bidirectional thyristor, it may be alternating current motor. The dc motor carbon brush is the same as the ac motor carbon brush, so the alternating current series excitation machine is used.

Q:Electric curtain choice dc motor or ac motor?: Ac motor cheap and long service life (up to only five years), but only for a hotel, office buildings and other projects, a lot of people think the products have passed 3 C certification, not a security issue, if not these products manufacturers of professional personnel to install, can pose a safety hazard, because they don't understand the internal structure of electric curtain motor, such things don't happen again.

Q:The difference between dc motor and ac motor: The speed adjustment method is different: The reason that the stator magnetic field is rotating is the three-phase symmetric alternating current which is 120 degrees behind each other, and the stator field is changed by alternating current. By changing the speed of alternating current changes, the speed of the motor can be changed. Dc power supply, dc motor is the same constant voltage, and the coil connected to the actual location change of formation, and connected to the coil of the actual location of the change only associated with the speed of the rotor rotation; As long as the speed of the rotor is changed, the rotor speed is proportional to the voltage, and the change of voltage can change the speed, which is the speed adjustment.

Q:What is the difference between a three-phase synchronous motor and a three-phase asynchronous motor search: We know that the three-phase power supply phase phase difference is the voltage on the phase between 120 degrees, three of the three-phase asynchronous motor stator winding on the spatial orientation also sent 120 degrees, so that when zhongtong into the three-phase power supply in the stator winding, stator windings creates a rotating magnetic field, the stator windings creates a rotating magnetic field, rotor conductors (cage) will cut the lines of magnetic force of a rotating magnetic field and induced current, the current in the rotor conducting bar and interact with a rotating magnetic field to produce electromagnetic force, electromagnetic force produced by electromagnetic torque drive rotor rotating magnetic field along the direction of rotation. In general, the actual speed of the motor is below the rotational speed of the rotating field. We call the three-phase motor an asynchronous motor. Three-phase synchronous motor is the three-phase generators of different working condition. There are N on three-phase synchronous motor rotor of magnetic pole, the pole to N - S - N - S - order, coil magnetic poles, all of the coil in series, the final ends, pick up on the rotor shaft of two copper on the slip ring, copper slip ring and the shaft is insulated.

Q:Why not use a commutator?: Instead of using the commutator, the alternating current is changing direction.I hope my answer will help you

Q:Which is better for a dc treadmill or an ac treadmill?: Depending on what you're using, if the home must be a dc motor: It is recommended that you consult the physical store before purchasing
