Q:MATLAB for ac asynchronous motor simulation
Is produced by the American MathWorks company business mathematical software MATLAB, for algorithm development, data visualization, data analysis and numerical calculation of senior technical computing language and interactive environment, mainly including two most of MATLAB and Simulink. MATLAB is very extensive!
Q:The application of single phase ac asynchronous motor in washing machine
Single phase ac asynchronous motor, which is is generally used to washing machine motor, the reason is tube sheet, because everyone has its principle, the structure is very understand, production technology has been very mature, and applied in the washing machine has decades of history. But as a result of this kind of motor is constant speed operation, when working through the belt drive and deceleration clutch to complete the conversion speed, torque, then finish washing machine washing, dehydration, respectively. The normal drum washing machine does not have a decelerating clutch, and only the first one is a reduction and transmission. It is accomplished by different poles of the motor in the washing and dehydration. The winding is made up of two poles/l2 poles or two poles/l6 poles. This will allow the washing rate to be around 40-60r/min, and the drying speed is about 400 to 600r/min. When people want to further improve the dehydrated speed, they also choose to change the voltage of the motor to change the voltage of the motor winding, which can be adjusted for dehydration. However, this method exists, the regulation range is small, the stability is poor and so on.
Q:The properties of single phase electromotive force of ac motor
The magnetic field generated from the electrotechnics, the three-phase alternating current (ac) is a rotating magnetic field, its speed n1 depends on current frequency f and rotating magnetic field of magnetic pole logarithmic p1, the relationship between them is: n1 = 60 f/p1
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 difference between dc motor and ac motor
Ac motor is only the stator winding and rotor cage shape is commonly, when during a stator winding in three-phase alternating current (ac), to produce a rotating magnetic field, rotor cutting lines of magnetic force movement, the induced electromotive force and induced magnetic fields, are produced by the interaction of two magnetic field drive motor rotation. Dc motors have two windings, a stator winding, a rotor winding, the stator zhongtong with direct current, a fixed magnetic field generated, passing a current in the rotor is, based on the function of electric conductor in magnetic field by force, and the effect of the rotor after electrify force, so that it rolls up, adjust the size of the current in the rotor, can change the speed of the motor, dc motor speed smooth, can realize stepless speed regulation. Now frequency conversion technology is mature, so use more and more frequency control of motor speed, dc motor without the answer
Q:About 100W ac motor is better than dc motor
The answer is very specific. Ac motor and dc motor are used for different purposes, you can reconnect according to the theory, the industry experience of your relevant industry is applied. That would be better.
Q:How does the motor select ac contactor
The communication contactor consists mainly of four parts: (1) electromagnetic system, including attracting coils, moving iron core and static iron core; (2) the contact system, including three main contact heads and one to two sets of regular open, often closed auxiliary contacts, is connected to the moving iron core. (3) an arc extinguishing device, which has a general capacity of communication contacts with an arc extinguishing device, so as to cut off the arc of the arc rapidly, avoiding the burning main contact; (4) insulation case and accessories, all kinds of spring, transmission mechanism, short circuit ring, terminal column etc.
Q:According to the power of motor, how to select the contactor and switch?
Select the circuit breaker as follows: The capacity of the motor is set to X (kW), the rated current of the motor as: 2 * X (A), in general, choose the circuit breaker rated current capacity shell frame is 4 * X (A), thermal rating of the breaker tripping current choice for (2.5 ~ 3.2) * X (A). For example: motor power 7.5 (kW), rated current of 15 (A), the capacity of circuit breaker should be 32 (A). Motor power (kW), 55, 110 (A) current rating, the rating of the breaker shell frame current capacity should be 250 (A), the circuit breaker rated heat tripping current choice for around 150 (A). The contact choice is the same as (3.5 ~ 4) * X (A). Note: the fan, pump circuit breaker and the contactor choose to be larger, because they have a longer start time, and the start torque is larger. 4, conductor selection: choose according to the rated current of the motor, generally 1.5 times the rated current, but want to consider laying environment, laying mode, multiplied by the appropriate factor.
Q:Which is better for a dc treadmill or an ac treadmill?
Depending on what you're using, if the home must be a dc motor: It is recommended that you consult the physical store before purchasing
Q:What is dc and ac servo motor?? What are the features?
Upstairs said too much load is professional enough ` ` ` ` ` ` dc servo motor servo motor is better in terms of regulating speed But in the ac servo motor in with local power was not rarely used ` ` ` ` ` ac and dc servo motor has brought my brush There are ac motor without brush with brush can adjust the power of the rotor to realize the speed of the motor But in a motor with brush need to use a period of time will have to change the brush each have an advantage See you in what place ` ` `
