Q:Why do elevator door motors use dc instead of ac?
Because the dc voltage is more stable.Dc voltage reliability and stability are high.
Q:Ac asynchronous generator principle
Asynchronous generator rotor is higher than the synchronous speed, the stator magnetic field will be of induction coil cutting, voltage and current, if the power grid, the grid frequency control are the synchronous speed. If it is not incorporated into the grid, its synchronous speed will be determined by the combination of the generator's speed and load.
Q:The structural difference between ac motor and dc motor
the structure of the synchronous motors have to be different. Compared with asynchronous motor (objective) (2) the principle of synchronous motor Understand the synchronous motor speed is constant, not change according to the load. Synchronous motor speed cannot adjust. 1, the working principle of dc motor General understanding of 2, the structure of the dc motor is divided into two parts: the stator and rotor. Remember the stator and the rotor is composed of a few parts, note: don't confuse commutating pole and commutator, remember the two of them. The stator includes: main pole, stand, commutating pole, brush device and so on. The rotor includes: the armature iron core, the armature winding, commutator, shaft and fan, etc. 3, dc motor excitation method Dc motor performance is closely related to its excitation mode, dc motor excitation method usually has four kinds: dc separately excited motor, dc shunt motor, dc series motor and dc compound motor. Mastering the respective features of four ways: dc separately excited motor: exciting winding and armature contact without electricity, excitation circuit is made up of other dc power supply. So the exciting current is not affected by the armature terminal voltage or armature current. Dc shunt motor, shunt winding ends voltage is the voltage on both ends of the armature, but exciting winding with fine wire coils, the number of turns a lot, so has larger resistance, made by his exciting current is small. Dc series motor:
Q:About 100W ac motor is better than dc motor
Depending on what you do with the motor, each has its own characteristics. The main difference between ac and dc motors is that the power supply is different, the ac motor USES alternating current, and the generator is alternating current. Direct current motors use direct current, and generators emit dc points. The advantage of dc motor (compared to ac motor) is the ability to achieve economic and smooth speed regulation. Ac motors need to be able to do this using a converter, an electromagnetic regulator, etc. Power and speed must be the same speed of dc motor and ac motor, dc motor price is a little more expensive, mainly because it must have a complex "commutator" to realize the ac/dc conversion. This also increases the manufacturing cost of dc motors.
Q:Three-phase ac motor star row and delta connection?
Three-phase winding delta connection Three-phase asynchronous motor winding delta connection, when the power of a phase (L3) circuit, by the winding with cz series and winding ax again after parallel hybrid circuit of stator current whether meet the phase condition, the need to be calculated to determine. Because of the three-phase symmetric winding structure, the three-phase excitation impedance is equal, namely, Zma = Zmb = Zmc = Zm < Φ, the three phase stator current are: A = 0 12 / (Zm < Φ) = < - Φ, 0 = 0 c = 12 b/(2 Zm < Φ) = / 2 < - Φ. The current in the three-phase winding is visible, but the current phase is the same, and the current is not satisfied with the phase condition. Three-phase winding delta connection, three-phase asynchronous motor open phase, not only unable to start, lacks when starting the stator current is very big, if not in time to cut off the power supply, motor will be destroyed immediately. This is quite different from normal starting and must be taken seriously.
Q:How to eliminate the electromotive force of ac motor
It is wrong to eliminate the anti-electromotive force of ac motor, which is the electromotive force that is opposite to the electromotive force of the power supply. There are multiple power sources in the circuit that can be turned against electromotive force. For example, two metal bars that cut the magnetic field in the same way back to the road may have an anti-electromotive force. There may be an anti-electromotive force in the presence of the electromotive electromotive force and induced electromotive force. In the case of a coil, the current of the electric current changes in the end of the coil. For example, the variation of voltage between the inductors in the LC oscillator circuit is strongly associated with the anti-electromotive force. The electromotive force is also produced when the motor coil is turning.
Q:How does the brush motor control the positive and backward rotation?
Usually have a brush motor circuit with dc power supply, as long as change the brush across the electrodes at the ends of the power supply, change the direction of the input current, can change the motor and reversing.
Q:When the ac servo motor is turned off, the rotor shaft is tight
If there is no brake device, it indicates that the load is not installed properly, which can cause rotational difficulty. Solution: loosen the load and turn the motor separately. The structure of ac servo motor can be divided into two parts, the stator part and the rotor part. The structure of the stator is basically the same as the stator of the rotating transformer, and in the stator iron core, there is also a two-phase winding of the Angle of 90 degree Angle. One group is the excitation winding, the other is the control winding, the ac servo motor is a two-phase ac motor. When ac servo motor is used, the excitation voltage Uf is applied at both ends of the excitation winding, and the control voltage is applied on both ends of the winding winding. When the stator winding is combined with the voltage, the servo motor will soon turn. Going into the field winding and control winding current to produce a rotating magnetic field in the motor, the rotating magnetic field to determine the steering motor, when any one of favorite on winding voltage inverting, the direction of the rotating magnetic field is changed, the direction of the motor is also changing.
Q:What is the regulation method of ac motor? What are the different features
Friend, one, change the logarithmic speed control method: change the red way of the stator winding to change the stator pole of the cage motor to achieve the speed adjustment. Two, frequency control method: changing the frequency of the motor stator power by using the frequency converter, changing the speed control method of the synchronous speed. Three, cascade speed regulation method: cascade speed regulation refers to the wound rotor motor rotor loop series adjustable the additional potential to change the slip of the motor, to achieve the purpose of speed control. Most of the slip power is absorbed by series of additional potential to recycle produce additional device, the absorption of returning the slip power grid or conversion of energy use. According to the slip power utilization way, cascade speed regulation can be divided into motor cascade speed regulation, mechanical cascade speed regulation and thyristor cascade speed regulation form, adopts thyristor cascade speed regulation. Four, wound rotor motor rotor series resistance speed control methods: line type asynchronous motor rotor string into the additional resistance, make the slip of the motor, motor under low speed running.
Q:What is an ac induction motor
In the rotor, there is no direct input alternating current, and a conductor with closed circuit on the rotor. Do the relative motion of a rotating magnetic field and rotor, the rotor on the closing of the conductor cutting current lines of magnetic force, magnetic field and the current and the stator's rotating magnetic field interaction, so as to drive the rotor rotation. From the above narrative, the current in the rotor is induced by a stator rotating field, so it is called an induction motor
