Q:The electric fan is a dc motor, or the ac motor is good, why?
Alternating current (ac). Direct Current, or DC, is a Current that does not make periodic changes in direction and time. AC (alternating current, AC) for short. A current in which the magnitude and direction of a periodic change are made periodically. Alternating current (ac) is to use ac generator, in the process of power generation, more uniform distribution of magnetic pole is according to certain Angle on a circle, make the power generation process, each coil is cutting lines, with much of the poles, each of the lines of magnetic force produced by magnetic pole was cut of voltage and current are change by string pattern, so can continuously produce stable current. Domestic ac frequency is 50 hz, namely change 50 times per second. In some countries, the frequency of the alternating current (ac) is 60 hz, namely changes 60 times per second. Of course there are other frequency. Such as electronic circuit of square wave, triangle, etc., but these waveforms of alternating current (ac) is not a conductor cutting lines, but a capacitor charging and discharging, switch transistor work.
Q:The structure of the ac motor
Ac motor is a machine that transforms electrical energy into mechanical energy. The ac motor is composed of a stator winding that generates a magnetic field and a stator winding and a rotating armature or rotor. An electric motor is made from the phenomenon of force rotation in the magnetic field. Ac motor consists of stator and rotor and the stator and the rotor is to use the same power supply, so the direction of the current in the stator and rotor changes always synchronized, the coil in the direction of current changed, became the current in the electromagnet direction at the same time, according to the left hand rule, magnetic coil suffered direction invariable, the coil can continue to turn down. The communication engine is working with this principle. The main purpose of ac motor: ac motor is more efficient, no smoke, no smell, no pollution, no noise. Due to its series of advantages, it is widely used in industrial and agricultural production, transportation, national defense, commercial and household electrical appliances, medical equipment and so on.
Q:What is the difference between ac motor and dc motor?
The dc feature: (1) the speed of regulation is good. The so-called "speed regulating performance" means that the motor changes the speed of the motor under certain load conditions. Direct current electromotor can achieve uniform, smooth stepless speed adjustment under heavy load conditions, and the speed adjustment is wider. The starting torque is large. The speed adjustment can be achieved evenly and economically. Therefore, all machines that start or demand uniform speed of rotation under heavy load. Communication features: The ac motor is more efficient, no smoke, no smell, no pollution and less noise. Due to its series of advantages, it is widely used in industrial and agricultural production, transportation, national defense, commercial and household electrical appliances, medical equipment and so on
Q:What is the difference between ac servo motor and three-phase ac asynchronous motor?
Stepper motor is the electrical pulse signal into angular displacement or line displacement of the stepper motor open-loop control yuan, in the case of the overload, motor speed, stop position depends only on the pulse signal frequency and pulse number, and not affected by load change, when the stepper driver receives a pulse signal, it is driving a stepper motor, set the direction of a fixed Angle, known as the "step Angle", its rotation is based on the Angle of the fixed step by step.
Q:Is the servo motor a dc motor or ac motor?
What is a dc motor? Answer: the output or input for the direct current to the rotation of the motor, known as the dc motor 2, a: what is ac motor output or input for the rotation of the ac power motor, known as 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:The vector control ac motor drive is the converter?
Simply put, vector control is to decouple the magnetic chain from the torque, and the regulator of the two can be designed to achieve the high performance speed adjustment of ac motor. Vector control method is based on slip frequency control of speed sensorless vector control method of vector control mode, and has a speed sensor vector control mode, etc. In this way, a three-phase asynchronous motor can be controlled by a dc motor, which is the same as the static and dynamic performance of dc speed control system. So that's the encyclopedia. That's pretty good. The concept of vector control was first discovered by Siemens engineers in a graduate thesis, which is widely used in domestic inverters. The traditional V/F control is more advanced and the advantages are obvious. The current frequency converter also has a control called direct torque control (DTC), which is only done by Siemens and ABB, and the DTC controls are more advanced. Which one doesn't understand
Q:The moment of inertia per motor is equal to the inertia ratio?
This formula is a conservation of kinetic energy: the kinetic energy of the single axis is 1/2 by J times omega squared. J is the moment of inertia for the angular velocity omega, kinetic energy is conserved, the kinetic energy is equal to the kinetic energy of the low speed shaft of high-speed shaft, there are: Jo * omega squared = J1 o * 1 omega squared, then simplify equation can get inertia ratio is the square of the acceleration ratio, which is the square of the velocity ratio.
Q:What is the difference between dc, alternator motor, and how the motor works
Generator is usually send ac dc converter (Ann is probably what you said dc generator), such as ordinary power station is to use such a generator. You can only use ac ac motor (such as dot chronograph), direct current motor can use alternating current (ac) and direct current (household electric light can use battery (direct current), for example, you can also use socket (alternating current).
Q:Does ac motor use the upper hall sensor
There are temperature sensors that can monitor winding temperature and avoid burning coils; There is a near switch or other sensor switch that can monitor the number of revolutions, or block the protection.
