Q:Which price is higher, AC motor or direct current motor? Which one has a longer service life?
1, under the premise of the same capacity, because the DC motor sales volume is small, copper is used more, so the price is more expensive than the AC motor;2 because of brush DC motor needs to be replaced frequently, if included in the life, the working life of DC motor AC motor is short, if not included in the replacement of the working life of two kinds of brush, the service life of the motor is basically the same
Q:How is the rated current of three-phase AC motor calculated?
Rated current (1.732 In=Pn/ * Un * n * cos Phi ETA).Where Pn is the nominal rated power, rated voltage Un, COS with n rated power factor, rated efficiency.Note that the power refers to the power output shaft, Pn/ is the input electric power.
Q:AC or DC motors for rolling gate motors?
Roll gate, also known as "rolling door", is a lot of joint activities of the doors and pieces connected together, in a fixed slide, with the center of the scroll above the center of the rotating door up and down.Roll gate (gate) is suitable for commercial appearance, garage, shopping malls, hospitals, factories and mines, enterprises and other public places or houses.
Q:How to connect the AC motor?
The single-phase motor has three terminals, the two terminals are connected to the fire line, and one to the zero line.
Q:Who knows the main difference between DC motor and AC motor, I hope to say a little more simple, thank you
DC characteristic:(1) good speed control performance. The so-called "speed performance" refers to the motor in a certain load conditions, according to the needs of artificially change the speed of the motor. The DC motor can achieve uniform and smooth stepless speed regulation under heavy load condition, and the speed range is wide. (two) starting torque is large. The speed regulation can be realized uniformly and economically. Therefore, all the machines which start or require uniform speed regulation under heavy load, such as large reversible rolling mills, winches, electric locomotives, trams, etc., are all driven by DC motors and motors.Communication characteristics:The AC motor has higher working efficiency, no smoke and dust, no pollution to the environment and little noise. Because of its series of advantages, it is widely used in industry and agriculture, transportation, national defence, commerce and home appliance, medical equipment and so on.
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:Causes of insulation breakdown in AC motor voltage withstand test
For various reasons, the insulation parts are weak in AC motor, and the breakdown of the weak parts of the insulation in the withstand voltage test
Q:AC motor control chip
Alternating current machine: a machine used to realize the mutual conversion of mechanical energy and alternating current energy. AC motor has become the most common motor because of the great development of AC power system. Compared to the AC motor and DC motor, because there is no commutator (see DC motor commutation), therefore has the advantages of simple structure, convenient manufacture, relatively strong, easy to make high speed motor, high voltage, high current, large capacity. The coverage of AC motor power greatly, from a few watts to several 101000 watts, even millions of kilowatts. In the early 1980s, the largest turbo generator reached 1 million 500 thousand kilowatts. The [1-2] AC motor was invented by Nicola Tesla, an American scientist from Serbia.
Q:AC motor: use gear variable or frequency conversion?
The advantages of variable frequency speed control is that a wide range of stepless speed regulation can be achieved within a range of any speed, at the time of transmission, the motor does not need to stop. Now the price of converter is not very high. But there are disadvantages, the reliability of electronic products is much worse than the reliability of mechanical products, even the normal operation is also prone to problems. And when there is a problem that the speed of the speed in the rated speed is a constant torque speed regulation process, that is to say its speed down, while torque did not change, the output power is motor becomes small. The device will not work on certain load characteristics. At this time, it is necessary to use the gear change structure to speed down at a high speed, then decelerate under the gear change mechanism to obtain large power.
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.
