- Q:About 100W ac motor is better than dc motor
- For ac generator, it can realize the energy of the "direct" back to the grid (but must ensure that the four conditions: the same voltage amplitude, phase, phase sequence, same same frequency); But dc generator power inverter is required (convert alternating current to direct current (dc) according to the process of rectification, the process of convert dc to ac inverter), to feedback to the grid. So it also needs to increase the power inverter.
- Q:The calculation method of the weight of copper wire used for ac motor
- The calculation method of the weight of copper wire used for ac motor
- Q:How does dc motor change ac motor
- But between dc motor and ac motor can't convert each other, this is because their manufacturing process and machine structure is different, the design from the start then can not be changed, unless you have taken apart the motor to have done
- Q:How do ac motors keep moving in the same direction?
- Most of the ac motor rotor is not current, power is in the little excitation current of synchronous motor synchronous runtime. Running in the rotor is current, this is in a rotating magnetic field induced current, the rotation of the rotor is also want to rely on the induced current, this is because the wire out of the current is induced in a rotating magnetic field, and wire in the magnetic field force, thus the rotor to turn up, until than the speed of the rotating magnetic field of the lower speed stability, this is the principle of asynchronous motor, so as long as the rotating magnetic field to the same, the motor to the same, how to obtain a rotating magnetic field, a direct current is not, the formation of the three-phase alternating current (ac) is itself a generator stator induced current in the rotor rotating magnetic field, so as long as he is input into the coil on the difference of 120 degrees, can be formed on the stator rotating magnetic field, single phase is somewhat hard to understand, but if you can put the sinusoidal magnetic field is decomposed into two same size changes, in the opposite direction of the synthesis of two rotating magnetic field results, as long as the rotor turns up later, and two the relative speed of the rotating magnetic field induced by the electric current cannot be integrated to zero, still can go up, just start up more troublesome.
- Q:The application of single phase ac asynchronous motor in washing machine
- Washing machine motor should be called: capacitive single-phase asynchronous motor. The principle is on the startup winding in series a proper capacitor, due to the capacitor current lagging behind its voltage 90 degrees, so can produce a deflection on the stator magnetic field, the motor rotation. A washing machine is a clean appliance that USES electricity to produce mechanical functions to wash clothes. The washing capacity is divided into two categories: household and collective. China requires washing capacity in under 6 kg belong to household washing machine: household washing machine mainly by the body, wash to take off the bucket (some wash and take off the bucket separately), drive and control system, etc, some still is equipped with heating device. Washing machines generally refer to the use of water as the main cleaning fluid, which is different from the use of special cleaning solution and usually the dry cleaning which is responsible for the special person.
- Q:Why does dc motor reduce the voltage regulating ac motor?
- The rotational speed of the ac motor is determined by the rotational speed of the rotating field, while the rotational speed of the rotating field is only related to the frequency and the magnetic poles. The frequency is fixed, and the magnetic poles are determined by the structure of the motor, which cannot be changed in the course of operation, so it is quite difficult to adjust the speed of the ac motor. The variable speed of dc motor can be obtained from the hardness of its mechanical properties, which is the relationship between the torque of the motor and the rotational speed. Beta = dM/dn. Type in the beta is hardness, it is the differential ratio of torque and rotational speed, beta is hard characteristics, on the other hand is soft features, need speed can be as long as the soft characteristics of dc motor, series motor, when the load increases, its speed will come down.
- Q:What is the difference between the three-phase ac motor and the second phase
- The three-phase asynchronous motor is composed of stator and rotor, its stator winding is a three-phase symmetric winding and USES symmetrical power supply. The two phase motor specifies the motor for the two phase winding. Two phase motors are divided into two types: drive and servo. Most household appliances and small electrical appliances (single phase) asynchronous motors are two phase driven motors. The two-phase servo motor of control is controlled, the two phase winding of the stator is respectively the excitation winding and the control winding, which is 90 degree Angle in space.
- Q:Three-phase asynchronous ac motor electric speed formula?
- The "extreme number" of a three-phase asynchronous motor is the number of magnetic poles specified in the subfield. The connection mode of stator winding is different, and different poles of stator magnetic field can be formed. The number of poles chosen for the motor is determined by the speed required by the load. The electric current of the motor is only related to the voltage and power of the motor. The three-phase ac motor generates N, S, magnetic poles for each coil, and the number of magnetic poles per machine is the number of poles. Because the poles come in pairs, the motors have two, four, six, eight... Extremely.
- Q:Can ac motors be used to speed control?
- Only the frequency converter motor can be used to adjust the speed of the transducer, and the ordinary motor can not be adjusted by the transducer. But it's ok to start ac motors with a frequency converter. Because when the speed is low, the ventilation of the electric motors deteriorates, and the fever is severe enough to keep working.
- Q:What is the control speed for ac servo motors?
- It is estimated that you should use an external pulse control servo driver, and you can control the speed of the servo motor by controlling the frequency of the servo drive pulse. Japanese general maximum speed corresponding to the pulse frequency of 500 k by the proportion relation, you change your pulse output frequency of the controller, to control the speed of the servo motor.
