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?
There are books in the book. Do you mean to change direction and change direction? Ac motor subrotors and stators The current changes in two current directions It's going to change the same way
Q:The type of speed adjustment of ac motor and the difference between them
There are three types of ac motor speeds common in industry. 1, the slip motor speed -- -- -- -- -- - on the motor output shaft is equipped with a pair of electromagnetic coupling, speed tests to adjust the magnetic field of the coupling with a set of speed. (not very much now, the disadvantage is inefficiency, the advantage is that it can be adjusted without speed.)
Q:How does the communication motor work?
Tesla coil to form a rotating magnetic field, rotating magnetic field in the cage of alternating flux change, squirrel cage induction electromotive force formation, formation of induced current, induced current in the magnetic field force, produce with rotation, when balance, motor steady work.
Q:The same power ac motor is more expensive than the dc
Is the same power ac motor more expensive or more expensive? The price is of course the dc welder. But you welding, non-ferrous metal or welding have special requirements that you must use dc welding machine, because it has high no-load voltage. The arc easy. Wide range of welding current. Steady arc. The weld appearance, etc. If you weld a regular iron plate that's all you need to do with the ac welder.
Q:How to judge a three-phase ac motor
A visual inspection, Measure U1U2, V1V2, W1W2 resistance, the three-phase resistances should be equal, and the three phase maximum difference should not exceed 2% of the mean 3, if it's a multimeter, it's almost the same Monitor current and motor temperature after idle running
Q:There is a difference between ac frequency conversion and dc frequency conversion
To compare the differences, you must first understand the structure of the two. In order to realize the dc motor speed regulation, there are several ways: (1) in the winding internal series resistance, the method of reducing I increases the loss of the drag system, the mechanical performance is "soft", and now it is not necessary. (2) regulating the armature winding voltage U, which is by far the best method of regulating speed, has the following characteristics: A) the mechanical properties of the speed adjustment are constant, and the speed landing only changes with the armature voltage. B) to achieve stepless speed adjustment, zero speed adjustment C) because the main flux is constant, the motor rated current is constant, so the speed control process has a "constant torque" characteristic.
Q:How does ac motor winding be classified?
There are many kinds of ac motor winding, which are divided by phase and single phase and three-phase winding. It has a single layer winding and a two-layer winding. The single layer winding is the same type, single chain, cross chain and cross. Double layer winding and wave winding; The number of slots in each phase of each phase is an integer or a fraction, and there are two forms of slot and fraction. But the principles of the winding are consistent.
Q:How does the three-phase ac motor identify the phase
The star delta launch is a time relay for three ac contacts String resistance and reactance start are now rare, and resistance is usually not in the distribution box The circuit of the auto-reducing voltage is a little bit closer to the star delta, but it is applied to the motor that is more than 90KW, and the auto-transformer is in or near the cabinet
Q:Why does ac motor speed control system replace dc motor speed control system?
The PWM control is the control core of the ac speed control system, and the final implementation of any control algorithm is almost done in various PWM controls. Has been put forward and the PWM control scheme of practical application to more than a dozen, articles about PWM control technology in many famous electric power international conference, such as PESC, IECON, EPE has formed at the annual meeting
