Q:Please exchange the motor. Is it possible to adjust the speed with a governor?
Many domestic electric fans use bidirectional thyristor to do phase shift speed regulation. This kind of speed regulation is to reduce the input current so that the motor can not move fast and can only reduce the speed. Like the light desk lamp, it is forced to adjust.
Q:What are the classifications of AC motors?
According to the principle of AC motor can be divided into synchronous and asynchronous motor two categories, there are strict correspondence between the rotating speed and the AC synchronous motor frequency, speed in operation strictly constant; asynchronous motor speed with the change of the load change slightly.
Q:Why don't AC motors use commutators?
The principle of AC motor of DC motor is differentDC motor running by permanent magnet and coil production function to promote Miguel rotor, reversing to coil rotor 180 degrees (equivalent to the magnetic field direction 180 degrees) to maintain the current direction of the coil and the existing magnetic field to produce the correct momentAlternating current machines operate with rotating magnetic fields, rotating magnetic fields depend on the direction of the current, and alternating current has this property, so there is no need for commutatorHowever, this is not absolute, the DC motor can also use no commutator, AC can also use the commutator, and fixed rotor design relatedThe AC motor is used for excitation, that is, the magnetic field is provided to allow the coil to cut the magnetic field lines
Q:Rated speed of AC motor
The alternating current motor revolution =60f/p.f is the alternating current frequency.P is the magnetic pole, the logarithm.60 is minute minute numberA four pole motor is a pair of 2 poles, so the theoretical revolutions of the four pole motor are 1500 revolutions per minute. This is the revolution of the rotating magnetic field. The actual revolutions are less than those of the rotating magnetic field. The quadrupole motor is usually 1450 revolutions per minuteThe rotating principle of three phase asynchronous motorThe prerequisite of the three-phase asynchronous motor to rotate is to have a rotating magnetic field, and the stator winding of the three-phase asynchronous motor is used to generate a rotating magnetic field. As we know, but the voltage phase power phase between the difference of 120 degrees in phase three, a stator winding of the three-phase induction motor in the spatial direction is 120 degrees, so when in the stator windings in three-phase power, the stator winding will produce a rotating magnetic field, current per change a cycle of the rotating magnetic field in the space rotation, change of rotating speed and current rotating magnetic field is synchronized. The rotation speed of rotating magnetic field is: n=60f/P, f is power frequency, P is magnetic pole, logarithm and N unit is: revolutions per minute. According to this formula, we know that the speed of the motor is related to the number of poles and the frequency of the power supply
Q:Types of AC motor speed control and the difference between them
Frequency conversion speed, which is currently the most commonly used control methods, can achieve stepless speed regulation, the semiconductor converter (or circuit) to change the power supply frequency of the motor, the power (frequency =50HZ) change into the required frequency achieve the purpose of speed, or the above formula: =60f/ magnetic pole synchronous AC motor speed. The frequency of "F", the speed will change.
Q:Soybean milk machine AC motor or DC motor is good?
Ethanol is a flammable, volatile colorless transparent liquid at low temperature and atmospheric pressure. It can not be used directly because of its low toxicity and pure liquid;
Q:Why are electric hair dryers divided into direct current motors and alternating current motors? What are their differences?
AC motor: wind, make the sound small, more durable, hot and cold big difference, large volume, stable current to prevent overvoltage protection AC fever dead machine, most hair dryer is now all communication, have built-in motor protection diode
Q:Is the stepping motor an alternating current motor or a direct current motor?
Although the stepper motor has been widely used, but stepper motors can not be like ordinary DC motors, AC motors in the regular use. It must be composed of double ring pulse signal, power drive circuit and so on, and the control system can be used. Therefore, it is not easy to make good use of stepping motor. It involves many specialized knowledge, such as mechanical, electrical, electronic and computer. Stepping motor, as an actuator, is one of the key products of mechatronics. It is widely used in various automatic control systems. With the development of micro electronics and computer technology, the requirement of stepping motor is increasing day by day, and it is applied in every national economic field.
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:What are the advantages of a DC motor and an AC motor?
Direct current motor (D.C.machine) is a kind of motor that realizes the conversion between DC energy and mechanical energy. When it is used as an electric motor, it is a DC motor. It converts the electric energy into mechanical energy. When the generator is running, it is a DC generator and converts mechanical energy into electrical energy.
