- 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: What is the general ac motor in electrical design?
- Such as cooling fan, slurry pump and circulating pump units have special requirements, usually with a soft start and frequency converter (larger use 660 v, slightly smaller use 380 v) to control.
- Q: How does the three-phase ac motor achieve constant power or constant torque output
- Three phase asynchronous motors running on motor. Three-phase asynchronous motor rotor speed is lower than the speed of the rotating magnetic field, rotor winding due to there is relative motion between magnetic field and induced electromotive force and the current, electromagnetic torque and interact with the magnetic field, the realization of energy conversion. Compared with the single-phase asynchronous motor, the three-phase asynchronous motor performs well and saves all kinds of materials. According to the structure of rotor, three-phase asynchronous motors can be divided into caged and winding type. The asynchronous motor structure of the cage rotor is simple, reliable, lightweight and inexpensive, and is widely used. The main drawback is the difficulty of regulating speed. The rotor and stator of a winding type three-phase asynchronous motor also set up a three-phase winding, which is connected by a slide ring, a brush and an external rheostat. Adjusting rheostat resistance can improve the starting performance of the motor and adjust the speed of the motor.
- Q: The same power ac motor is more expensive than the dc
- Of course, dc is expensive, dc motor is much more complicated than the three-phase squirrel-cage ac motor.
- Q: What are the advantages of the dc welder and ac welder? The better one?
- compared with ac arc welding machine, dc welding arc stability, not easy broken arc and small six, splash. Dc arc welding machine can weld acid and alkaline welding rod, communication can only seven alkaline welding rod, welding machine prices, see you need to how much current welder, relatively speaking, dc welder expensive eight. Very save electricity, dc arc welding machine, is the development trend in the future. Personal recommendations dc welding machine. There is one of the biggest advantages is the dc welding machine is very light, 200 a to ten catties of convenient also move '
- 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: 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: How do ac motors keep moving in the same direction?
- Because the working principle of ac motor is formed stator rotating magnetic field, and then the rotor itself is a closed coil (induction motor) or a magnet (PMSM), the turning of the rotor only related to the direction of rotation of the magnetic field, magnetic field direction of rotation has been unchanged, it remains the same. This principle understanding more complicated than the direct current machine, single phase motor, in particular, the more complex, but the structure is simple. Can't use the principle of the dc motor to use ac motor, dc motor of main current is the same to the rotor, need to brush for phase to ensure the consistency of the turning of the rotor, and the ac motor is the main current to the stator, in order to form a rotating magnetic field.
- Q: How to control ac motor speed
- How the motor is controlled: Motor control refers to the control of the start, acceleration, operation, deceleration and stop of the motor. Depending on the type of motor and the use of motor, there are different requirements and purposes. For motor, it is controlled by motor, which is the purpose of fast starting, quick response, high efficiency, high torque output and high overload capability. Three phase asynchronous motor start-up methods include: Full voltage direct start, voltage drop start, increase rotor circuit resistance start. For the reduction of pressure, the main factors include: auto-transformer start, star delta change start, voltage change start. When the asynchronous motor starts, the rotor is at rest, its slip ratio s = 1. At this point, the rotor side of the t-type equivalent circuit is very low, so the starting current is large and the starting current can be reduced by lowering the voltage. Since the starting torque of the asynchronous motor is proportional to the voltage square, it is necessary to make sure that the motor has a certain starting capacity
- Q: What's the total number of ac motor governor? The most common, each principle, the detailed point, the master thank you Please be more careful, the principle means thank you
- Ac motor speed governor generally refers to the electromagnetic speed regulating motor controller. Now the gear speed machine, also called ac motor speed, the best you know that will you use it first.
