- Q: The electric spark machine USES ac motor or dc motor!
- The external power supply is ac, but the electric spark machining is dc, and there is a rectifier in the interior, and the dc resistance communication. By a half wave of positive and a negative half wave voltage is composed of alternating current (ac), and there is only one direction (positive or negative) of a certain voltage is dc pulse width; By the pulse of dc power induction, the induction is still a dc pulse, and if the ac is ac, a cycle will have a minimum of two ignition cycles, no drops, please take it.
- Q: What is the electrical Angle in the motor? What does it have to do with mechanical angles
- Commonly used three-phase brushless dc motor, there are generally three position sensor, the output waveform has two kinds: one kind is phase difference Angle 60 ° electrical, the other is a phase difference of 120 ° Angle. 1 on the poles, for example, phase difference of 120 ° electrical point of view, three position sensor space interval is 120 ° mechanical Angle; 2 on the poles, phase difference is 60 ° electrical point of view, the three position sensor space interval of 30 ° mechanical point of view.
- Q: Is the brushless dc motor a synchronous motor or asynchronous machine? Thank you very much!
- The principle of brushless dc motor is similar to that of permanent magnet ac synchronous motor, but not synchronous motor. Strictly speaking, synchronous motor refers to ac motor which is kept constant in normal operation and has a strict constant relation between speed and power frequency. Is a brushless dc motor speed or change with the load, the second is ac motor, no power frequency, and the frequency of the internal rotating magnetic field will change with the load. So I can only say that communicate with permanent magnet synchronous motor is the same principle, motor rotor is a permanent magnet, but brushless motor with position sensor to detect the rotor position after the stator winding in turn electricity to produce a rotating magnetic field, and ac synchronous motor made with an alternating current to produce a rotating magnetic field. Its movement principle has nothing to do with a brush dc motor, brushless dc motor has is produced by the magnetic field and rotor dynamics is the electromagnetic force after cutting magnetic induction line, is not between the poles of attraction.
- Q: Why not use a commutator?
- Because the dc motor changes the direction of the current through the commutator and the coil keeps rotating
- Q: What is the control speed for ac servo motors?
- By ac servo motor drives to work, of course, different types of servo motors have their rated speed, and speed control is achieved by the servo drive.
- Q: What is the difference between alternating current motors and dc motors?
- The same is true of their principle, which is the use of electromagnetic induction. Different is confidential by dc commutator to change the direction of current. To get a torque, principle, I would say, junior high school. Ac motor is to pass through it into the alternating current to produce a rotating magnetic field in the motor, and then is the law of electromagnetic induction. I wrote it myself, hoping to help the owner.
- Q: The calculation method of the weight of copper wire used for ac motor
- It is usually a cable-like cable which is twisted by several or several sets of wires (at least two of each set), which is insulated from each other
- Q: What are asynchronous motors and synchronous motors
- Symmetrical three phase winding ventilation with symmetrical three phase current, to produce a rotating magnetic field, magnetic field line cutting rotor winding, according to the principle of electromagnetic induction, rotor winding of e and I, rotor winding by the effect of electromagnetic force in the magnetic field, electromagnetic torque, which make the rotor rotation, the rotor output mechanical energy, drive the mechanical load. Rotor speed n < n0, so called asynchronous motor. S = (n0-n)/n0, which is called the slip rate, is an important parameter to the asynchronous (motion) machine. SN is the rated slip.
- 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: Does ac motor control circuit have to be communicated?
- In addition, the alternating current is a sinusoidal current, not a sudden change in the plot. It's a little bit of a gradient. So the magnetic field is also gradient. Instead of magnet, and ac motor in an iron core, the iron core in the gradient magnetic field induction current, magnetic field and the current must be pushing it normal rotation, of course also change. In other words, what you're saying is that the frequency invariant means that the external gradient is constant, but the induced magnetic field is related to the speed of rotation. And those motors that can shift gears are changed by changing the number of electrodes. For example: the current one period of the external gradient field turns a week, and now the two cycles of the tween magnetic field turn around for a week, not half the time!
