- Q:The properties of the single phase magnetic electromotive force of ac motor, the amplitude of its amplitude, the position of amplitude, and the frequency of the pulsations are related to the various factors
- The magnetic field generated from the electrotechnics, the three-phase alternating current (ac) is a rotating magnetic field, its speed n1 depends on current frequency f and rotating magnetic field of magnetic pole logarithmic p1, the relationship between them is: n1 = 60 f/p1
- Q:What is the starting method of ac motor?
- Start with 2. Star - triangle start. 3. Extension start. 4 drop press start.I hope my answer will help you.
- Q:Is the squirrel-cage motor communicating in three phases?
- The rodent motor can only show that his rotor is a mouselike, although it is an alternating current, but it does not indicate that it is a three-phase alternating current, or single phase alternating current. This depends on the winding and wiring of the stator winding of the motor. The three-phase motor is composed of three-phase winding, which usually leads to six terminals, delta connection and star connection. The individual also has a three lines after the inside of the line. A single phase motor is composed of two phase winding, which is divided between the main and the radial winding. The combination of the external capacitance and the radial winding is used to generate the rotating field. An electric motor is also a single phase, typically consisting of a winding, which relies on a short circuit ring on a pole shoe to form a rotating magnetic field. Be sure to distinguish between the use and the other
- Q:What kind of motor can be added
- This motor can only be adjusted by frequency conversion. Because of the lowering of the speed control, the electrical opportunity can not work, or even burn. It can also be used for speed reduction gear Governor (called) is a kind of automatic adjustment device, according to the change of the diesel engine load, it automatically increase or decrease in fuel injection pump oil, the diesel engine to run at a steady speed.
- Q:The difference between dc motor and ac motor
- Ac motor is only the stator winding and rotor cage shape is commonly, when during a stator winding in three-phase alternating current (ac), to produce a rotating magnetic field, rotor cutting lines of magnetic force movement, the induced electromotive force and induced magnetic fields, are produced by the interaction of two magnetic field drive motor rotation. Dc motors have two windings, a stator winding, a rotor winding, the stator zhongtong with direct current, a fixed magnetic field generated, passing a current in the rotor is, based on the function of electric conductor in magnetic field by force, and the effect of the rotor after electrify force, so that it rolls up, adjust the size of the current in the rotor, can change the speed of the motor, dc motor speed smooth, can realize stepless speed regulation. Now frequency conversion technology is mature, so use more and more frequency control of motor speed, dc motor without the answer
- Q:Direct current motor and ac motor, which is large, good, who invented
- As with the above, each has its own purpose, just like your hands and feet. Which one do you say is more useful?
- Q:Ac motor 110KW how much current
- If 380V motors, the rated current is 220A and a kilowatt is about 2 amperes. For other voltage grade, if you use power divided by the voltage (KV), the divided by the square root of 3, divided by the motor power factor, is the rated current of the motor. You look at
- Q:How to control ac motors with dc 24V voltage
- 24 v dc voltage cannot be applied to ac 24 v ac contactor, and buy less than 24 v ac contactor, can use a inverter to 24 v dc into 220 v ac voltage, and buy a 220 volt ac contactor with a button, the circuit connection is ok,
- Q:380v's ac motor operates under 330v voltage
- It should be because your motor is not heavy, but it should not be used. It is harmful to the motor.
- Q:How to eliminate the electromotive force of ac motor
- You have a fundamental error in this question. There must be an anti-electromotive force in the motor running as an electric motor. If you want to run the motor, you don't have a countercurrent, so the motor is running as a generator.
