- 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: Dc motor power 13KW for ac motor
- I don't think the power will change. The current and the voltage are going to change, but the product should not change
- Q: Ac motor speed control method
- Disadvantages: The maximum speed of the output shaft is 80% ~ 90% of the synchronous speed of the motor. The transition difference power of the speed adjustment process is converted into thermal energy and low efficiency. (7) the rotor resistance speed adjustment Advantages: The technical requirements are low and easy to master; The cost of equipment is low; No electromagnetic harmonic interference.
- Q: The alternating current is constantly changing, and how is the ac motor going to be controlled?
- There are many methods of rotating magnetic field, such as three-phase winding, single-phase shift phase, short circuit, pulse changing phase, etc.
- 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: According to the power of motor, how to select the contactor and switch?
- Based on the capacity of the three-phase squirrel-cage asynchronous motor, the calculation method for selecting circuit breaker, contactor, heat component and conductor is as follows: 1, the capacity of the motor is set to X (kW), the rated current of the motor as: 2 * X (A), in general, with the motor nameplate rated current of the difference is very small, if not sure, can take the motor manual check. For example: motor power 7.5 (kW), rated at 15 (A); The motor power 55 (kW), the rated current is 110 (A).
- Q: The structure of the ac motor
- Ac motor is a machine that transforms electrical energy into mechanical energy. The ac motor is composed of a stator iron core, wire wrap winding, stand, and other structures that are fixed in these parts. The rotor by
- Q: Direct current motor and ac motor, which is large, good, who invented
- The auster motor USES the principle of the magnetic effect of the current, and the principle is invented by the Danish physicist oster. He was born on August 14, 1777, in a family of pharmacists in rudjoin, langlang island. He was admitted to the university of Copenhagen in 1794 and a doctorate in 1799. He visited Germany and France in 1801-1803 and met many physicists and chemists. He was a professor of physics at the university of Copenhagen in 1806 and became executive secretary of the Danish royal society since 1815. In 1820, the royal society received the royal society award for the remarkable discovery of the magnetoelectric effect. In 1829, he was President of the Copenhagen institute of technology. He died in Copenhagen on March 9, 1851. He has studied physics, chemistry and philosophy too much. Due to the influence of Kant's philosophy and the natural philosophy of schelling, it is believed that natural forces can be transformed from one another, and the relationship between electricity and magnetism has been explored for a long time. In April 1820, the effect of the current on a magnetic needle, the magnetic effect of the current, was finally discovered. On July 21, the same year, he published his findings on the subject of an experiment on electroconflict in magnetic needles. This short paper to make Europe has had the enormous vibration physics, led to the emergence of a large number of experimental results, which has opened up a new field of physics ─ ─ electromagnetism. In 1934, the unit of strength of the magnetic field was named after "oster". In 1937 the American association of physics teachers set up the oster medal to reward physics teachers who contributed to physical teaching.
- Q: What is the control speed for ac servo motors?
- By ac servo motor drives to work, of course, different types of servo motors have their rated speed, and speed control is achieved by the servo drive.
- Q: The speed regulation performance of dc motor is very good. Why need ac motor?
- Compared with ac motor, dc motor is very good at the speed of adjustment, but it is difficult to maintain the high cost and high cost.
