- Q: Ac frequency conversion air conditioning compressor is synchronous motor and asynchronous motor
- Dc motor is synchronous and asynchronous, because the rotor speed of dc motor is related to voltage. Synchronous motor refers to the same frequency as the power supply. Ac ac is synchronous motor for dc motor. General synchronous motor is permanent magnet, replacing excitation with permanent magnet, can reduce volume and improve energy conversion efficiency. Synchronous motors are used in places with high speed requirements. The alignment and connection of the asynchronous motor's stator coils are the same as that of the synchronous motor, except that there is no permanent magnet or coil on the rotor, only an iron knot. Because with the frequency in a rotating magnetic field, rotor speed difference, thus induced in the rotor magnetic field, driving the rotor rotation, average speed is slower than the frequency of a beat, speed and the same frequency, because don't produce speed difference. The greater the speed difference, the greater the motor torque. The compressor is synchronous and asynchronous, only the synchronous motor is more efficient, the speed control is accurate. The asynchronous motor is suitable for high power compressor, such as central air conditioning. As for synchronous or asynchronous, the input is high voltage direct, because direct communication can't change frequency. The variable frequency air conditioning is used to change the ac frequency to control the speed. Turn alternating current into high voltage dc and then turn into three phase alternating current through high power IGBT. You can refer to the principle of the new energy electric motors, and the input is direct current, but the motor is a three-phase ac motor.
- Q: The application of single phase ac asynchronous motor in washing machine
- The machine that drives the washer is the motor. Selecting the motor at present, the washing machine has the following kinds: single phase ac asynchronous motor, single-phase series motor, permanent magnet brushless dc motor and switched reluctance motor. It is divided by the structure of the motor and the way of work; If the connection mode of the motor and load is divided, it can be divided into indirect drive and direct drive. Direct drive, the output shaft of the motor is directly connected with the load, and eliminates the central driving chain, which is a kind of both a short and advanced drive. The motor that carries out this type of drive is the direct drive motor. The tube says: direct drive motor. It's also called DD motor in English.
- Q: How does ac motor winding be classified?
- There are many kinds of ac motor winding, which are divided by phase and single phase and three-phase winding. It has a single layer winding and a two-layer winding. The single layer winding is the same type, single chain, cross chain and cross. Double layer winding and wave winding; The number of slots in each phase of each phase is an integer or a fraction, and there are two forms of slot and fraction. But the principles of the winding are consistent.
- Q: The motor in the hair dryer is ac motor, or dc motor
- Dc permanent magnet motor。Dc motor, series diode rectifier. Please adopt!.I hope my answer will help you.
- Q: Can two phase ac motor not be able to install governor?
- Small power can, high power (with centrifugal switch) not ok.A resistance governor can be installed
- Q: If the motor through reducer drive the load, the load moment of inertia is to convert to the motor shaft, namely, divided by the square of reduction ratio, and, after conversion of moment of inertia of the moment of inertia/motor = inertia ratio?
- Yes, in the transmission shaft system, the rotational inertia of the axis of rotation is the output axis of inertia (Je) to the calculation axis reduction of the ratio squared (I squared). In other words, from the low speed axis to the high-speed axis, the high-speed axis rotational inertia (Jo) = low velocity axis rotational inertia (J1) is the reduction of the speed of the inertia (I squared). From the high speed axis to the low-speed axis, the inertia of the low speed axis (J1) = high speed axis rotational inertia (Jo) x reduction (I squared). In the calculation, the deceleration ratio is greater than or equal to 1, which is the low speed shaft tooth number/high gear number. The high-speed axis is usually the motor shaft.
- Q: Permanent magnet motor is dc motor and ac motor
- A permanent magnet can be a dc motor or ac motor (for example, a home breeze fan). In the same way, no permanent magnet can be either a dc motor or ac motor, or even an alternating current. In contrast to electric excitation motor, permanent magnet motor, especially rare earth permanent magnet motor, has simple structure and reliable operation. Small volume and light weight; Small losses and high efficiency; Flexible and varied in shape and size of the motor and other significant advantages, and application scope is extremely broad, almost throughout the aerospace, defense, the areas of industrial and agricultural production and daily life.
- Q: Why does ac power connect capacitor
- The purpose of ac motor capacitance is to transfer the single phase alternating current to a phase difference of 90 degrees. The two phase alternating current (ac) into two groups and four groups, each motor coil winding, is formed in the motor rotating magnetic field, rotating magnetic field to produce induced current in the motor rotor, rotating magnetic field and the magnetic field produced by induced current in the opposite direction, by rotating magnetic field into a state push-pull rotation.
- Q: Does ac motor control circuit have to be communicated?
- In addition, the alternating current is a sinusoidal current, not a sudden change in the plot. It's a little bit of a gradient. So the magnetic field is also gradient. Instead of magnet, and ac motor in an iron core, the iron core in the gradient magnetic field induction current, magnetic field and the current must be pushing it normal rotation, of course also change. In other words, what you're saying is that the frequency invariant means that the external gradient is constant, but the induced magnetic field is related to the speed of rotation. And those motors that can shift gears are changed by changing the number of electrodes. For example: the current one period of the external gradient field turns a week, and now the two cycles of the tween magnetic field turn around for a week, not half the time!
- Q: What is the difference between the three-phase ac motor and the second phase
- No two phase motor, what do you mean by two phase motor is single-phase motor, is to connect two wires of that kind of, ha ha, is that after a fire a zero line, the so called single phase motor, three-phase motor is undoubtedly pick three root wire (wire is phase line, commonly known as wire), common single-phase motor rated voltage is 220 v, are not commonly used in industrial production, mainly used in civil, as there is no the three-phase motor is single-phase motor efficiency is high, so once the power requirements in kilowatts, or a few kilowatts can choose three-phase motor, like a home of the motor is single-phase motors, because the load is small, like some big motor in industrial production to 5000 kw, if the single-phase motor, if nothing else, the line is much more rough!
