- Q: The rated current of a single phase ac motor is several times that of an empty current.
- A small single-phase motor, which is rated at about twice the amount of an empty current
- Q: Ac motor speed control method
- You can change the frequency, you can change the logarithm of the magnetic pole, and you can change the difference in three ways
- Q: What does the motor center of the three-phase ac motor mean
- Center height refers to the height of the motor shaft to the base Angle of the seat. The length of the machine is used in the international letter of the letters: the "S" - the short stand, the M - the engine seat, the L - the long machine seat, is usually determined according to the length of the stator iron core. The "H" of 80 is 80mm
- 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: How does the current transformer in ac motor work?
- Ac current transformer in ac motor The effect is to make current phase difference Ac motor of current transformer is actually has a magnetic core inductance coil, inductance coil has the characteristics of the dc resistance communication, so that the current phase. The principle of ac motor is that the stator coil generates a rotating magnetic field, which makes the rotor spin fast. To produce a rotating magnetic field, the current transformer is required to make the current phase difference.
- Q: Why does ac motor speed control system replace dc motor speed control system?
- Especially microprocessor used in PWM technology and the digitized, pattern is constantly renovated, from the initial voltage waveform sine pursuit, the sinusoidal current waveform, and then to sinusoidal magnetic flux; The development of PWM control technology has undergone a continuous innovation and continuous improvement from the optimum efficiency, the lowest torque ripple, and the elimination of noise. So far, new proposals have been made to further prove that the technology is in the ascendant.
- 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: The type of speed adjustment of ac motor and the difference between them
- Speed regulating pole change motor -- -- -- -- -- - a specific motor internal to do particular winding, by motor different connection mode change polarity logarithm, get a different speed. Formula: the synchronous speed of ac motor is 60f/magnetic poles (f - - frequency), the magnetic poles are changed and the rotational speed is changed. The drawback is that it cannot be stepless speed adjustment (such as 2-4 pole motor, synchronous speed only two gears, the two poles are 3000, and then the 4 pole is 1500.
- Q: Why does ac power connect capacitor
- The purpose of ac motor capacitance is to transfer the single phase alternating current to a phase difference of 90 degrees. The two phase alternating current (ac) into two groups and four groups, each motor coil winding, is formed in the motor rotating magnetic field, rotating magnetic field to produce induced current in the motor rotor, rotating magnetic field and the magnetic field produced by induced current in the opposite direction, by rotating magnetic field into a state push-pull rotation.
- Q: How the ac motor works
- The principle of ac motors: the coils spin in the magnetic field. Do you know the principle of direct current electromotor? Dc motor commutator is used to automatically change the direction of the current in the coil, so that the coil stress direction is consistent and continuous rotation. So as long as the guarantee coil stress direction is consistent, continuous rotary motor will be. Ac motor is the application of this.
