Q: How to distinguish dc motor from ac motor?: The difference between dc motor and ac motor is, of course, the type of power supply. One is dc and one is communication. The stator of a dc motor is a fixed magnetic field, and the direct current is rotating within the stator by the electric brush of the rotor forming a changing magnetic field around it. In industrial enterprises, dc motors are generally used for standby machinery or security equipment that can be reliably run because of the relative reliability of dc power sources. As the input voltage changes due to dc motor speed can also change, so need to often speed used dc motor is also many, such as trolley, electric locomotive, and so on. Ac motor is the rotational force generated by the rotating field of the stator that inducts the electric potential on the rotor. Its speed is generally fixed. But because of its simple structure and convenient power supply, it is widely used in various enterprises and families. Small to household washing machine, vacuum cleaner, big to huge pump, machine tool and so on, all use ac electric machine. Since communication is easier to obtain and easier to deliver, most of the electric machinery we use today is driven by ac motors.

Q: There are several methods for alternating current motor: Other answer Ac asynchronous motor reverse connect braking has two forms: 1) the power brake, reverse connect braking - the electric motor of the three-phase power exchange of two lines, make access to the motor phase sequence, on the other hand, a rotating magnetic field inversion (in contrast to the rotor turning), the electromagnetic torque is a braking torque, motor soon stopped, must stop the motor when power off, otherwise will reverse starting; 2) pour la reverse connect braking - motor work normally when the load torque pulling reverse rotation, at this time of the electromagnetic torque is a braking torque, the braking torque motor reverse speed is not fast, but will not stop the motor;

Q: The converter can control which motors: Frequency converter (Variable frequency Drive, VFDS) is the application of frequency conversion technology and microelectronic technology, by changing the way to control the motor power frequency ac motor power control equipment. Inverter is mainly composed of rectifier (ac to dc), filter, inverter (dc to ac), brake unit, drive unit, detection unit micro processing unit, etc. Internal IGBT inverter on the open circuit to adjust the output of the power supply voltage and frequency, based on the actual needs of the motor to provide the needed power supply voltage, thus achieve the goal of energy saving and speed, in addition, the protection of the inverter and there are many functions, such as over-current, over-voltage protection, overload protection, etc. With the increasing degree of industrial automation, the frequency converter has been widely used.

Q: The rated speed of ac motor: The alternating current of the ac motor = 60f/p.f is the frequency of alternating current. P is the magnetic pole. 60 is a minute. Four pole motor is 2 to the poles. So the theory of a quadrupole motor number is 1500 r/min. This is a rotating magnetic field of revolution. Actual revolutions is lower than a rotating magnetic field of revolution. Quadrupole motor is generally 1450 revolutions per minute

Q: Please communicate the motor. It is possible to speed the speed with a governor: Many household electric fans using bidirectional thyristor phase shift control of motor speed, this kind of speed is actually reduce the input current make motor with fixed running quickly and can only reduce the speed. Like dimming lamps, they are forced to regulate.

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: The speed regulation performance of dc motor is very good. Why need ac motor?: One is that the dc motor needs a powerful dc power supply, while the ac motor is not needed. Second, the electric brush system of dc motor is mechanical friction, which requires constant maintenance (changing the brush, cleaning commutator), ac motor without it. Third, the spark of a carbon brush can cause electromagnetic interference in a large number of electronic systems. Four is that the volume of dc motors with power is larger than the ac motor. Five is that the current frequency converter is mature enough to meet most of the speed adjustment requirements.

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.

Q: What is the difference between dc motor and ac motor?: Series type of ac motor and dc motor structure, such as hair dryer, crusher, hand electric drill, etc. Used in the motor, just can't like dc motor with permanent magnets to generate the magnetic field. There is a commutator, carbon brush, there is electric spark in the work, the noise is bigger. General induction ac motor commutator and carbon brush, the input current of stator, rotor coil produces eddy current magnetic field, no spark, noise is small in work.

Q: How to control ac motor with single-chip microcontroller: Control methods: The output of a single chip machine is connected to a photoelectric coupler, combined with a triode and relay circuit. To see how much voltage the relay corresponds to, one end of the relay has to be connected to the voltage, and the other end to the triode. 3, one end of the relay is suitable for alternating current voltage of ac motor, and ac motor at the other end. Two relay control for positive and reverse transfer. In simple terms, the small relays are controlled by the output of a single chip, the small relays control motor
