- 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: How does ac servo motor change direction?
- The private subdivision simulates input, and pulse input, the input terminals of the simulated input are negative 0 - - 10 volts (reverse) and positive 0 - -10 volt (positive pass). Pulse input, in addition to pulse, and direction control.
- Q: Is the extruder in 110KW a good ac motor or dc motor?
- Now we use frequency conversion to ac motor. Very few dc machines, because dc machines need to be maintained too often.
- Q: Why should ac motors be used in parallel with capacitors
- You say "ac motor" all have no rotational moment!!! With capacitor in parallel to the two sent 90 degrees (jet lag) rotational torque coils, potential difference (90 degrees) to stagger time (small single-phase motor) it mainly provide starting torque
- Q: Who knows the main difference between dc motor and ac motor
- The two point poles 1 and 2 dc motors are forever 1 is positive and 2 is negative and the ac motor is a very shallow sign of positive and negative points
- Q: What are the advantages of the dc welder and ac welder? The better one?
- The current of the dc welder is not "over zero", it is not easy to break arc, the arc is stable, this is its greatest advantage. The secondary voltage peak of transformer is certain, the dc arc welding machine is higher than the ac welder, it is easier to draw the arc. The dc welder is more than the ac welder, and the cost is slightly higher
- Q: How does ac motor speed control
- The rated speed n = 60f/p (1-s) = synchronous speed of N1 (1-s) f power frequency The speed adjustment of the power frequency is changed by using the frequency converter, the speed adjustment range is large, the stability is smooth and the mechanical properties are hard. This is the reduction in the nominal load speed. It belongs to stepless speed adjustment. Suitable for most three-phase squirrel cage asynchronous motor. The speed adjustment of the magnetic pole is changed, it is the speed adjustment, the speed adjustment is poor, and it is commonly used for metal cutting machine tool. Change the speed adjustment. (1) rotor circuit resistance: used for ac winding asynchronous motor. The speed of adjustment is small, the resistance has to consume power, the motor is inefficient. It is used for cranes. (2) it changes the voltage regulation of the power supply, the speed adjustment is small, the torque decreases greatly with the voltage drop, and the three-phase machine is not used. For single-phase motor speed adjustment, such as fan searching. (3) a series of speed adjustment, the essence is that the rotor introduces additional electromotive force, and changes its size to speed adjustment. It is also used only for winding motor, but efficiency is improved.
- Q: Is it that all ac motors are bi-directional
- In addition to changing the power supply, some motors change the direction of the winding or the rotor direction
- Q: Common problems with ac motor
- ?the bearing room is too big. (3) tighten the screws; (4) there is clutter in the motor. Electromagnetic aspect: (1) the motor is overloaded; (2) the three-phase current imbalance; (3) missing phases; (4) stator, a short circuit failure of the rotor winding; (5) the welding part of the cage rotor welding is caused by cutting. What are the causes of overheating of motor bearings? The motor itself: (1) the inner and outer ring of the bearing is tightly coupled; (2) there is a problem with the parts, such as seats, ends, shafts, etc. (3) improper bearings; (4) the bearings are not lubricated or the bearings are not cleaned, and the grease contains sundries; (5) shaft current. Usage: (1) the unit is improperly installed, such as the shaft of the motor shaft and the shaft of the device that is dragged. (2) the pulley was pulled tight; (3) the bearing is not well maintained, the grease is not sufficient or exceeds the use period, and the hair dries out. What is the cause of low electrical resistance? (1) the windings of the winding or water intrusion; (2) gathering dust or oil on the windings; (3) aging of insulation; (4) the insulation of the motor lead or the junction plate.
- Q: What is the connection of ac motor
- Three phase ac motor has two kinds of connection Star: three phase lines of three terminals connected to three terminals, and the following three terminals with wire or metal pieces.
