- Q: Ac motor 110KW how much current
- But it's very short, so it's usually 1.3 to 1.7 times, and that's 1.5 times. You also have to think about the coefficient of use, and you take one of the motors. 223 * 1.5 * 0.9 = 301 A
- Q: The ac motor is not positive and negative, so how do you achieve positive and reverse?
- Ac motor? Single item of pole type electric motor does not turn positively! Three exchanges of any two phase sequence will be easy if you have more mundane motors!
- Q: What happens to the capacitance of ac motor
- A little bit is ok, if big, it is easy to burn the machine, you can try for yourself, change the new capacitor to take a look. (less turn for a moment is ok) and see if it is immediately fever, if, so before you the motor or a large capacitance, but I think you are still in a first try out as large as before,
- 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
- Q: Can ac motors be used to speed control?
- If you don't have a low frequency field running, you can choose to ordinary asynchronous motor, if there is a low frequency operation that suggest you still choose frequency conversion motor, is mainly ordinary motor cooling fan is connected to the motor spindle, fan heat dissipating capacity of low frequency, then the heat dissipation of the motor can't guarantee. But the frequency conversion machine is the opposite, because the fan is controlled separately, it is forced wind cold. It doesn't matter even at low frequencies. I hope I can help you.
- Q: How to implement the start-stop of three-phase ac motor with the contactor?
- The contactor is divided into AC contactor (voltage AC) and DC contactor (DC), which is applied to power, distribution and electricity. A contactor is a term that refers to a magnetic field that is used by an industrial electrical current to generate a magnetic field, which makes the contact close to the control load.
- Q: Which is better for a dc treadmill or an ac treadmill?
- On electricity to run the market at present is dc motor, but the dc motor is ac motor, durable, safe, that is to say, market exchange treadmill will be dominant in the future. Running on electricity, suggest buying a running machine. If commercial electricity runs in clubs for a long time, then you have to buy an ac treadmill.
- Q: Dc motor and ac motor, which is better for mechanical hands?
- DC power amplification, but not to control steering servo DC signal, and is adjustable wide pulse signal, so as to obtain the high precision control. Pure DC signal can also control the rudder Angle, but control may be too long, for example, if you need to 31 degrees from left 30 degrees to the left, with DC signal may need to 1 second, and using PWM pulse may need only 0.1 seconds
- Q: What are the similarities and differences between the dc brushless and the ac brushless motor?
- General use on the generator excitation, brushless dc brushless ac motor is generally, also have a plenty of a brush, a motor is generally small motor brush, because of the need to solve the short circuit current of commutation time, so communication has the motor will not be too big, just imagine the dc motor, dc motor and reversing problems, so the dc motor will not do! Dc brushless motor actually is ac motor, commonly used in generator excitation system!
- Q: What is the difference between a three-phase synchronous motor and a three-phase asynchronous motor search
- Synchronous motor as a generator running, the rotor winding with dc excitation at work, by external mechanical force to drive the rotor rotation, the direction of the n0 and torque T direction on the contrary, the stator of the induced emf (electromagnetic induction principle), and then the output voltage. When the synchronous motor runs, the rotor winding works with the dc excitation, the stator 3 phase alternating current, which generates the rotating magnetic field and the rotor synchronous rotation. Asynchronous motor and synchronous motor is the most fundamental difference between the stator any excitation, without excitation for asynchronous, should only produce relative movement, will have the effect of cutting magnetic induction line (or flux change), will produce electromagnetic induction force (i.e., ampere force). With the excitation, the stator can be regarded as a magnet, with fixed NS poles, which will be synchronized with the rotating field, so the synchronous motor is called. (magnets attract) three-phase asynchronous motor to spin the prerequisite is to have a rotating magnetic field, three-phase asynchronous motor stator winding is used to produce a rotating magnetic field
