- Q:What will be the result of the power supply to ac motor after the rectifier (not filtering)?
- The ac motor will not be able to transfer the pulse direct current, the light is hot.
- Q:What is the difference between ac servo motor and three-phase ac asynchronous motor?
- Low frequency characteristics In low speed, the step motor is prone to low frequency vibration. The vibration frequency is related to the load condition and drive performance, and the frequency of vibration is generally considered to be half the frequency of the motor. The low-frequency vibrations, determined by the principle of stepping motor, are very bad for the normal operation of the machine. When the stepper motor work in low speed, general damping technology should be adopted to overcome the low frequency vibration phenomenon, such as add damper on motor, or drive the segmentation technology, etc. Ac servo motors are very stable, even at low speeds. Ac servo system has a resonance suppression function, can cover the mechanical rigidity, and internal system has the function of frequency resolution (FFT), can detect the mechanical resonance point, is advantageous for the system adjustment.
- Q:Does the train use dc or ac?
- It turns out that there is a small generator on the bus, which is the chassis of the coach or the generator that hangs on the frame. Generator through a belt connected to the installed on the axle of the pulley, when the train operation, the wheel rolling, the belt driven in generators and power generation, supply all kinds of electrical appliances use. When the train stops, the wheel does not move, and the generator no longer generates electricity. In order to ensure that the passenger car can be powered by normal power, it is equipped with a battery power system on the passenger bus. When driving, it converts electrical energy from a generator into chemical energy savings, a process called battery charging. When parking, it converts chemical energy into electricity and sends electricity to electricity, a process called battery discharge. Railway on the installation of the generator and battery compartment is called "mother", is not installed the car called "car", the mother car and child: the proportion of the general 1:1. This wheel is powered by a belt that drives a generator, called a shaft generator. This type of electricity is widely used in China's railway trains. This way of power supply of power generation equipment, use is the largest number of J type three-phase ac induction generator, the power only 5 kw, obviously not suitable for power consumption big hundreds of new air conditioning bus
- Q:Any 220V ac motor can be reversed?
- Theoretically yes. Now there are only three lines of single phase motor. This type of motor is made by the manufacturer, which connects the starting winding and the main winding to the interior directly. This motor cannot be turned upside down by an external method if it is not modified.
- Q:How does dc motor change ac motor
- The dc is dc, the communication is communication。I hope my answer will 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:What are the advantages of ac generators compared to dc motors? Why is it that today's big generators are talking about generating electricity and getting rid of dc power?
- Alternator's advantage is the advantage of developing energy, now is the main ac power on the consumption of energy, and this kind of generator maintenance convenient, and durable. And dc generator for dc energy consumption only, in addition to small household electrical appliances is large motor with this kind of dc power supply, small home appliance is not necessary to buy a dc generator for power supply? And large motor, need large generators to supply power, to know the large generator driven by either hydraulic or mechanical energy or wind need to consume large amounts of diesel oil, water or wind, and want to have big permanent magnet iron core or high power rectifier devices. Permanent magnetic iron core is one of the best in the dc generator, but also need high power permanent magnet generating large generator drive, and is very difficult to start, or excitation coil dc power supply, need to control dc again. A lot of trouble. Instead of using alternating current, the whole flow can also save energy. This is just my personal opinion, I don't know if it's right or wrong.
- Q:Three-phase asynchronous ac motor electric speed formula?
- In China, the power frequency is 50 Hertz, so the synchronous speed of the dipole motor is 3000 RPM/min, and the synchronous speed of the quadrupole motor is 1500 revolutions per minute, and so on. The rotor of an asynchronous motor is always slower than or above its rotating magnetic field, and the name of asynchrony comes in. The difference between the rotor speed of the asynchronous motor and the rotational field speed (called the transvariation) is usually within 10%. Because of this, the actual speed of the three-phase asynchronous motor will be lower than that. If the synchronous speed of 6 is 1000 revolutions, the actual speed is 960 RPM/min.
- 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:What kind of motor can be added
- Speed regulating motor (220 v) : the speed controller adjustable speed range: 130 ~ 1350 RPM, with speed sensor, inside the feedback control, so the power frequency have change, it should have no change of revolution.
