- Q:Is the synchronous motor not communicating? Why do you say that brushless dc is a type of synchronous motor? Exclude o
- Brushless dc motor is not a smooth direct current, but pulse square wave. Like synchronous motors, speed is associated with frequency of square waves.
- Q:How does ac motor winding be classified?
- There are many kinds of ac motor winding, which are divided by phase and single phase and three-phase winding. It has a single layer winding and a two-layer winding. The single layer winding is the same type, single chain, cross chain and cross. Double layer winding and wave winding; The number of slots in each phase of each phase is an integer or a fraction, and there are two forms of slot and fraction. But the principles of the winding are consistent.
- Q:What is the speed of the general motors
- The motor synchronous speed is n = 60f/p n speed f power frequency p electromagnetism log. Common motor speed is 960, 1400, 2800 RPM. More.
- Q:The ac motor with more than one kilowatt will be activated by the launcher
- If just use ordinary motor (do not include the power plant, industrial production using motor), you can refer to: civil, public power grid points directly power supply transformer and village power supply two kinds, the former is 11 kw allows direct start the following, which is 15 kw In fact, there are four factors to consider: When the motor starts, the voltage on the distribution bus at various levels meets the normal requirements of other devices; Mechanical energy is able to withstand the shock torque when the motor is fully pressed. The motor itself can withstand the shock of full pressure starting. There is no special requirement for motor start.
- Q:How does dc motor change ac motor
- You have to know that electrical motors and motors, generators and motors can be interchangeable, whether dc or ac,
- Q:Single phase synchronous alternator working principle
- Without dc voltage on the brush, constant speed by prime mover drag the armature to counterclockwise rotation, on both sides of the coil is cutting lines of magnetic force under different magnetic polarity, respectively, in which the induction electromotive force, electromotive force direction determined by the right-hand rule. This electromagnetic situation is shown on the graph. Due to the armature rotate continuously, and, therefore, must take the current carrying conductor in magnetic field from the coil side ab and CD alternately cutting lines under the N pole and S pole, although each side of coil and the coil in the direction of induction electromotive force is alternating. Induction electromotive force in the coil is A kind of alternating electromotive force, and in the brush. A, B side electromotive force for dc electromotive force (some say exactly, is A kind of direction invariable pulse vibration electromotive force). Because, the armature in the rotation process, no matter the armature turn to what position, due to the effect of the reversing of the commutator with brush, brush A by commutator segment of electromotive force always is the cutting edge of electromotive force by the coil in N pole magnetic field lines, therefore, brush A always have A positive polarity. In the same way, the brush B has always negative polarity, so the brush can lead to the same change in the direction of the pulse. If the number of coils per pole increases, the pulse vibration decreases, and the dc electromotive force can be obtained. That's how the dc generator works. It also shows that the zidc generator is essentially an ac generator with a commutator.
- Q:In the ac motor, he is excited, excited, and excited. What is the difference between
- He wound, is that the rotor is a set of power supply, the stator excitation coil is another power supply, two sets of power supply is independent and not directly on the electric contact, unless the closed-loop control of the motor in general mechanical and electrical properties are hard, and is adjustable speed and torque. That features more hard!
- Q:What are the similarities and differences between the dc brushless and the ac brushless motor?
- So-called no brush, brushless, is also is this kind of motor does not rely on brush to change the polarity of the armature current, and usually by position detection device, such as hall, the light code disc detection such as location, and then in accordance with a certain control method, according to the position signal to change the polarity of the armature current.
- Q:Why don't I have a dc 12V without a brush motor and I can connect to a third phase 12V?
- A magnetic field that is the same as a synchronous motor is also a rotating field. It's just going to go from 120 degrees to 180 degrees, and the motors are going to work, and they're not much less efficient. (only the brushless dc motor and some series of excited motor can connect the ac power)
- Q:Electric curtain choice dc motor or ac motor?
- Ac motor cheap and long service life (up to only five years), but only for a hotel, office buildings and other projects, a lot of people think the products have passed 3 C certification, not a security issue, if not these products manufacturers of professional personnel to install, can pose a safety hazard, because they don't understand the internal structure of electric curtain motor, such things don't happen again.
