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:How does a three-phase ac motor form a circuit?
The method of circuit of three-phase ac motor is as follows: When the three-phase stator winding of the motor (the difference between a 120 - degree Angle), access after the three-phase alternating current (ac), will produce a rotating magnetic field, the rotating magnetic field cutting rotor winding, thus produce induced current in the rotor winding is closed (rotor winding path), the rotor of current-carrying conductor under the effect of the stator rotating magnetic field will produce electromagnetic force, as to form the electromagnetic torque on the motor shaft, motor rotation, and the motor rotation direction is the same as the rotating magnetic field direction. Three-phase motor, refers to the three phase when the motor stator winding Angle of 120 degrees (the difference between electric), to the three-phase alternating current (ac), will produce a rotating magnetic field, the rotating magnetic field cutting rotor winding, thus produce induced current in the rotor winding, rotor winding is closed path).
Q:What is an ac driver? And the principle! Thank you very much!
Speed response performance is different It takes between 200 and 400 milliseconds for a step motor to accelerate from rest to a working speed (usually a few hundred revolutions per minute). Better acceleration performance of the ac servo system, a panasonic MSMA 400 w ac servo motor as an example, from static accelerated to the rated speed 3000 RPM it takes only a few milliseconds, can be used for quick start-stop control occasions. To sum up, the ac servo system is superior to stepping motor in many performance aspects. But you can also use stepping motors to do the motor on a less demanding occasion. Therefore, in the design of the control system, the factors such as controlling requirements and cost, etc., should be taken into consideration.
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 are the main parts of alternators?
 ends of the generator is aluminum alloy die casting, after the end cover with brush holder. Silicon diode rectifier is used will have a three-phase alternating current generator, rectifier dc. It is composed of six diode, respectively, pressure plate and the rear end cover in aluminum alloy component, a three-phase bridge rectifier circuit. x0d generator of the cathode by iron, perfectly on the back end cover three diode cathode tube, its shell is positive, three diode shell together become a generator of the cathode, the center for pipe cathode lead; In a component on a board of three diode as the anode tube, its shell is negative, the three diode shell meet together for the anode, the center lead to the anode of the pipe.
Q:What is the difference between a brushless ac motor and a brushless dc motor?
The difference between brushless and brush is commonly used for dc motors. The ac motor does not have a brush and no brush.
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:When the ac servo motor is turned off, the rotor shaft is tight
If there is no brake device, it indicates that the load is not installed properly, which can cause rotational difficulty. Solution: loosen the load and turn the motor separately. The structure of ac servo motor can be divided into two parts, the stator part and the rotor part. The structure of the stator is basically the same as the stator of the rotating transformer, and in the stator iron core, there is also a two-phase winding of the Angle of 90 degree Angle. One group is the excitation winding, the other is the control winding, the ac servo motor is a two-phase ac motor. When ac servo motor is used, the excitation voltage Uf is applied at both ends of the excitation winding, and the control voltage is applied on both ends of the winding winding. When the stator winding is combined with the voltage, the servo motor will soon turn. Going into the field winding and control winding current to produce a rotating magnetic field in the motor, the rotating magnetic field to determine the steering motor, when any one of favorite on winding voltage inverting, the direction of the rotating magnetic field is changed, the direction of the motor is also changing.
Q:Why is a single phase ac motor that can be adjusted by voltage
Synchronous motor torque = motor power/(2 * PI * RPM / 60) N · m. 2, the frequency of the alternating current (ac) of 50 hz, synthesis of the synchronous speed of the magnetic field of 50 r/s, which is 3000 r/min, if motor more than a pair of poles, further analysis can also get synchronous speed. 3, 4 pole synchronous speed is 1500r/min, 6 pole synchronous speed is 1000r/min, 8 pole synchronous speed is 750r/min. The asynchronous motor speed = (60 * frequency/logarithmic) times the error rate. 5, the synchronous motor stator voltage is reduced, according to article 1, motor torque, asynchronous motor, conforms to article 4 formula, slip is less than 1, motor speed down. If the torque of the motor is in balance with the external resistance torque, the slip rate is stable, the speed is stable and the motor is successful. After the 5th and 6th, the stator voltage of the motor is improved, and the process is reversed. The voltage regulation is implemented in this way.
Q:The ac motor is not positive and negative, so how do you achieve positive and reverse?
Three-phase motor fixed wiring to produce a circular rotating magnetic field, single phase motors through a secondary coil series capacitor formed an elliptic rotating magnetic field, as long as the connection method is fixed, the above two is fixed in the direction of the field Change the wiring method, can change the rotation method of the magnetic field, realize positive and backward turn
