Q:AC servo motors generally choose synchronous or asynchronous?
This will be based on your purpose, such as CNC machine tools feed shaft, generally use AC synchronous servo motor, spindle general use AC asynchronous motor. The synchronous machine of the same power is more expensive than the asynchronous machine
Q:AC motor: use gear variable or frequency conversion?
The advantages of variable frequency speed control is that a wide range of stepless speed regulation can be achieved within a range of any speed, at the time of transmission, the motor does not need to stop. Now the price of converter is not very high. But there are disadvantages, the reliability of electronic products is much worse than the reliability of mechanical products, even the normal operation is also prone to problems. And when there is a problem that the speed of the speed in the rated speed is a constant torque speed regulation process, that is to say its speed down, while torque did not change, the output power is motor becomes small. The device will not work on certain load characteristics. At this time, it is necessary to use the gear change structure to speed down at a high speed, then decelerate under the gear change mechanism to obtain large power.
Q:Panasonic servo motor A4 series, AC synchronous motor or AC asynchronous motor?
The servo motor can make the control speed and position accuracy very accurate, and the voltage signal can be converted into torque and speed to drive the control object. The servo motor rotor speed control by the input signal, and can respond quickly, in the automatic control system, used as actuators, and electromechanical time constant, high linearity, initiating voltage characteristics, to convert signals received from the motor shaft angular displacement or angular velocity output. Divided into DC and AC servo motor two major categories, the main feature is that when the signal voltage is zero, no rotation phenomenon, the speed increases with the torque and uniform decline.
Q:Which is better, alternating current tubular motor and direct current tubular motor?
The advantages of DC motors (compared with AC motors) are: to achieve economic, smooth speed characteristics. And AC motor need to use inverter, electromagnetic regulator and other components to achieve this function.With the same power, the same speed (must be the same speed) compared with DC motor and AC motor, DC motor of the expensive price point, mainly because of its complicated structure must have "commutator" to achieve AC-DC conversion. This also increases the manufacturing cost of DC motors to a certain extent.
Q:What is the difference between AC motor speed and DC motor speed?
Because the exchange is easier to obtain, easier to transport, so at present we use most of the electric machinery is AC motor driven, AC motor applications more widely.
Q:How to control the speed of AC motor
The method of increasing rotor circuit startup is applicable to wound rotor, deep groove rotor and double cage rotor. For squirrel cage rotors, this method cannot be used.When increasing the rotor resistance of an induction motor, the maximum torque of the motor will not be affected, but the maximum torque will occur, and the motor torque slip curve will be compressed along the slip axis. As the motor curve shows that the slip ratio rises first and then decreases, the starting torque of the motor will increase. But its numerical value is affected by the maximum torque of the motor.The starting modes of single-phase asynchronous motor include capacitor start, resistance start, PTC start and so on.
Q:Which price is higher, AC motor or direct current motor? Which one has a longer service life?
1, under the premise of the same capacity, because the DC motor sales volume is small, copper is used more, so the price is more expensive than the AC motor;2 because of brush DC motor needs to be replaced frequently, if included in the life, the working life of DC motor AC motor is short, if not included in the replacement of the working life of two kinds of brush, the service life of the motor is basically the same
Q:What is the difference between stepping motor and servo motor and three-phase asynchronous motor? What are the advantages of their differences?
Principle: when the asynchronous motor, the motor stator windings of AC, will produce a rotating magnetic field, the rotating magnetic field cutting rotor windings, thus the induced current in the rotor winding, the rotor conductor ampacity will produce electromagnetic force in the stator rotating magnetic field, so as to form the electromagnetic torque of the rotating shaft of the motor and drive motor rotate, and the rotation direction of the motor and the rotating magnetic field of the same direction. As the rotor of asynchronous motor and stator rotating magnetic field in the same direction, different rotating speed, there is a slip, so called asynchronous motor.AdvantageCompared with other motors, the utility model has the advantages of simple structure, convenient manufacture, good operation performance, and various material saving and low cost.shortcomingPower factor hysteresis, light load, low power factor, poor speed regulation performance.
Q:What's the difference between a three-phase AC motor and a DC motor?
In general, the armature winding of the three-phase AC motor is on the stator, and the armature winding of the direct current motor is on the rotor;
Q:AC speed regulation motor + turbo reducer instead of cam cutter + AC motor?
If the worm gear reducer is used, though the worm gear pair can be made in reverse direction, the backlash of the worm gear will cause errors, i.e. backlash. The backlash generated by the backlash of the worm gear is much larger than the error of the cam cutter. Generally, the back clearance of the ordinary worm gear reducer can reach over 15 arc points. That would be a difference of 1/4 degrees. If the rotary disc diameter is large, the backlash is very terrible, the center deviation 1/4 degrees, the radius of 500 place would be how much can calculate. Therefore, the use of worm, generally have aided detection apparatus, using a switch to detect the position you want to stop, such as detection photoelectric switch block inspection of several indexing arrangement, to immediately stop the motor stop in the detection signal. However, due to the inertia of the motor, there will be a bit of overshoot after stopping. Therefore, it is necessary to put some parameters into the design, and then to design the fast position for the adjustable structure.
