- Q: There are several methods for alternating current motor
- Other answer Ac asynchronous motor reverse connect braking has two forms: 1) the power brake, reverse connect braking - the electric motor of the three-phase power exchange of two lines, make access to the motor phase sequence, on the other hand, a rotating magnetic field inversion (in contrast to the rotor turning), the electromagnetic torque is a braking torque, motor soon stopped, must stop the motor when power off, otherwise will reverse starting; 2) pour la reverse connect braking - motor work normally when the load torque pulling reverse rotation, at this time of the electromagnetic torque is a braking torque, the braking torque motor reverse speed is not fast, but will not stop the motor;
- Q: Why does a single phase ac motor have to be a capacitor to start running?
- Because only the formation of a rotating magnetic field, a squirrel cage rotor spins, only increase the startup winding, but start winding must pass a capacitance phase shift make start winding current advanced main coil current 90 degrees, the formation of a rotating magnetic field motor to rotate (high power motor start will remove after start capacitance).
- Q: The application of single phase ac asynchronous motor in washing machine
- Single phase ac asynchronous motor, which is is generally used to washing machine motor, the reason is tube sheet, because everyone has its principle, the structure is very understand, production technology has been very mature, and applied in the washing machine has decades of history. But as a result of this kind of motor is constant speed operation, when working through the belt drive and deceleration clutch to complete the conversion speed, torque, then finish washing machine washing, dehydration, respectively. The normal drum washing machine does not have a decelerating clutch, and only the first one is a reduction and transmission. It is accomplished by different poles of the motor in the washing and dehydration. The winding is made up of two poles/l2 poles or two poles/l6 poles. This will allow the washing rate to be around 40-60r/min, and the drying speed is about 400 to 600r/min. When people want to further improve the dehydrated speed, they also choose to change the voltage of the motor to change the voltage of the motor winding, which can be adjusted for dehydration. However, this method exists, the regulation range is small, the stability is poor and so on.
- Q: Why is dc motor less efficient than ac motor
- As the name suggests, dc motors use direct current as a power source. Ac motor is used as an ac power supply. According to the structure, the principle of dc motor is relatively simple, but the structure is complex and not easy to maintain.
- Q: Why not use a commutator?
- The difference between an engine and an electric motor is that there is no electric power on the engine, and the motor is connected to the power supply but not necessarily the other
- Q: What are the advantages of the dc welder and ac welder? The better one?
- compared with ac arc welding machine, dc welding arc stability, not easy broken arc and small six, splash. Dc arc welding machine can weld acid and alkaline welding rod, communication can only seven alkaline welding rod, welding machine prices, see you need to how much current welder, relatively speaking, dc welder expensive eight. Very save electricity, dc arc welding machine, is the development trend in the future. Personal recommendations dc welding machine. There is one of the biggest advantages is the dc welding machine is very light, 200 a to ten catties of convenient also move '
- Q: How do ac motors keep moving in the same direction?
- Typically by capacitance phase out another phase Angle difference of alternating current (ac) effect on the secondary coil and main coil integrated into a rotating magnetic field up to cut off the secondary coil. As for the synchronous motor, the principle of some trouble, basic is asynchronous motor rotor into a rotor as dc motor. When it starts to become asynchronous start, starts in electricity, the rotor into sync, ha ha, also forgot to tell you that a speed ratio of the motor is rotating magnetic field of low speed asynchronous motor, the same is called synchronous motor, the speed of the rotating magnetic field is the synchronous speed.
- Q: What are the similarities and differences between the dc brushless and the ac brushless motor?
- General use on the generator excitation, brushless dc brushless ac motor is generally, also have a plenty of a brush, a motor is generally small motor brush, because of the need to solve the short circuit current of commutation time, so communication has the motor will not be too big, just imagine the dc motor, dc motor and reversing problems, so the dc motor will not do! Dc brushless motor actually is ac motor, commonly used in generator excitation system!
- Q: Is the inductance of the stator winding of single phase ac motor constant? Does the inductance of the stator winding change when the motor turns?
- This is a conceptual error! Inductance is the fixed index of inductance element! Like resistors of resistance! Capacitance value! The inductance is not inductive! Not electromagnetic induction strength! It doesn't change when it's fixed! The inductance is the design data! Inductive and inductive strength is the actual application data!
- Q: The vector control ac motor drive is the converter?
- I can send you the data, there are two kinds of actuators, one is the servo actuator, one is the frequency converter, there is the mailbox, I send you an EMAIL.
