Q:How to speed the AC motor?
The speed of three-phase asynchronous motor is expressed as:N= (60 * f / P) * (1s) =n1 (1s),N - motor speed (R / min, revolutions per minute); F - power frequency (Hz);P - the polar logarithm of an electric motor;S - slip ratio of motor, s= (N1 - n) / n;Synchronous speed n1 motor, n1= (60 * f / P) (R / min).There is a way to change the speed of an electric motor:1, change the power frequency;2, change the number of poles of the motor;3, change the speed difference.
Q:Is the single-phase carbon brush motor a direct current motor or an AC motor?
(1) motor is a DC motor with single-phase brushless motor or AC, there is also some DC motor AC and DC motor, such as most of the pistol electric drill AC and DC motor, AC and DC power can also be used to use.(2) the power supply of rectifier bridge is not from positive and negative pole, and the power supply of rectifier bridge must have positive and negative poles, otherwise it is not power supply of rectifier bridge.(3) bidirectional thyristor should be used in AC circuit. If your motor speed is bidirectional thyristor, it may be AC and DC motor.DC motor carbon brush and AC motor carbon brush is the same, so there are AC and DC dual series motor.
Q:Why should a single-phase AC motor start with a capacitor?
A starting winding is added to the stator, and the starting winding and the main winding are separated by 90 degrees in space. Connect a suitable capacitor starting after winding, the winding equivalent circuit becomes a resistor inductor and capacitor in series, as long as the capacitance value of the phase angle of voltage current meet ahead of a certain angle, such as 30 degrees; at the same time, if the current running winding perceptual hysteresis voltage of 60 degrees, then the current phase two the winding difference reached 90 degrees, the so-called phase separation principle. In this way, the two currents, which differ by 90 degrees in time, pass through two windings that are 90 degrees apart in space, which will produce (two phase) rotating magnetic fields in space, and the motor will rotate naturally.
Q:STC microcontroller through the relay control AC motor, in the motor start and stop the moment will be interrupted multiple times
You've taken some of the usual anti jamming measures, but the key issues haven't been solved.1, the relay is isolated, without individual power supply, the photoelectric coupler input, if need to power (such as 6N137), must be separate power supply.Signal 2, optocoupler out, if it is low speed optocoupler, decreased along with gentle, easy to false triggering, you can add a Schmitt trigger in optocoupler after. It should solve your problem.3, SCM procedures can also do some anti disturbance processing, for example, some of the microcontroller's external interrupt, anti disturbance processing, you can open. If not, you can use the query operation, for example, each 10uS query IO once, 5 times continuously high, think that it is effective to obtain a high level, high level, set a mark, marked effective, inquiry into the 5 consecutive low level (if the middle high level again just count) is deemed effective falling edge.
Q:How to synchronize two ordinary AC motors?
The motor does not need to be synchronized. As long as the same type of motor on the line, the two sides automatically run at the same time into the synchronous state. As long as the load on both sides of the motor is not the same. When a motor is switched a little faster, the load of the motor is increased, the speed of the motor is slowed down automatically, the load of the other motor is reduced, and the speed of the motor is increased naturally.
Q:How to change DC motor to AC motor?
DC motor to AC motor, single motor is good to change, as long as the power and speed approximate. The key is to change the control, DC speed control device to be replaced by AC control system, especially if you want to speed, you must install the inverter, the motor also choose AC inverter three-phase asynchronous motor.You mentioned the 2200rpm, I do not know whether the rated speed or actual use speed, DC motor should have rated speed and weak magnetic speed of two gears. If you are 2200rpm rated, about 45 kW AC machine to choose 4 pole motor, 4 pole motor rated speed is 1500rpm (50Hz), need to increase the frequency, we must choose the variable frequency motor, variable frequency motor 50Hz under constant torque, constant power 50~100Hz, should be able to meet the needs of equipment.As for the Japanese motor, which sell, it is difficult to say. Even if you can buy it, it should be sky high. If there are no special requirements, it can be changed into a three-phase asynchronous motor made in china. Should fully meet the electrical requirements.I've done a lot of imported motor localization project, Japan also had many alternative motors, such as MITSUBISHI, Hitachi, Yaskawa and so on, the German motor can use domestic alternatives, not to mention the small Japanese!
Q:What are the classifications of AC motors?
According to the different rotor structure, three-phase asynchronous motor can be divided into two major categories, squirrel cage and winding. Among them, squirrel cage is the most widely used.
Q:Why does high-speed rail use AC traction motors in China?
Synchronous excitation motor, more devices, more annoying, generally used in firepower, water power plants. It can be said that the world's larger power motors (1MW or more), basically all communication. The power generation is basically synchronous, and the motor is basically asynchronous. In addition, I give you a data, the world about 70% of the power consumption of the motor, there are 70% of which is asynchronous motor.
Q:Why is an AC motor more popular than a direct current motor? System description, thank you.
When it comes to AC motor, said first alternating current, alternating current is often used in our daily life, low price, wide use, AC Alternating Current AC motor can adapt to any electrical equipment, is no exception, the reason is the three-phase alternating current of each phase is 120 degrees, 360 degrees, this is just a three-phase AC motor is welcome to good, so the AC motor will be popularized
Q:Can the welding line of AC welding machine be dead?
The welding line of AC welding machine is the two line of electric welding machine.The welding wire caused by electric shock accidents, because the two line is low voltage (no-load voltage generally 50 - 90V), people understand the causes of electric shock, often mistakenly think that the welding line two times is "safe", leading to accidents causing death two line not uncommon a shipyard is a young female welder, welding is the cabin, the cabin due to high temperature and poor ventilation, body sweating, canvas overalls and leather gloves are wet. When replacing the electrode holder when touched, because of spasm fall backward, falling out of the neck in the holder, failed to cause electric shock accident died after death. The accident tells us that the two line voltage of the welder is low, but it is enough to kill.
