Q:How can I change the alternating current welding machine into a DC welder?
This is: ZXG series silicon rectifier (dead silicon) arc welding machine, AC arc welding machine itself power factor is lower, plus rectifier loss will be lower. The power consumption is too large and uneconomical. It has belonged to the sort of our welder.
Q:How to synchronize two ordinary AC motors?
I'm afraid it's not easy. Ordinary AC motors are asynchronous motors. Two identical motors, when the load is exactly the same, and at the same time, it is possible to synchronize, but this synchronization is prone to damage. Personal view, for reference only.
Q:Types of AC motor speed control and the difference between them
Motor variable pole speed regulation ---- a specific motor internal to do a specific winding, through the motor of different wiring mode to change the motor magnetic pole logarithm, get different speed. Formula: synchronous motor speed, =60f/, magnetic pole logarithm (f--- frequency), magnetic pole logarithm change, the speed also changed. The disadvantage is not stepless speed regulation (such as 2-4 pole motor, synchronous speed is only two gear, when connected to the 2 pole is 3000 rpm, when connected to the 4 pole, is 1500 rpm.
Q:AC servo motor why drive?
In addition, the servo controller does not have the ability of logic control, if need servo motor first slow turn, then turn fast, then to stop somewhere and then reverse, and so on, these signals are more responsible for the upper controller of the servo controller, such as PLC, such as motion controller.
Q:What's the difference between a three-phase asynchronous motor and an ordinary one?
The three-phase asynchronous motor cooling fan is fixed on the shaft of the motor of the same, and the rotation speed of the motor, low frequency operation, low speed fan also, cooling capacity is greatly decreased, the heat generated from the motor, which will burn the motor. And the structure of frequency conversion motor and the ability to withstand voltage have been specially designed to meet the requirements of high speed and high harmonics.
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:What is the neutral point of an alternating current motor? How to determine whether the neutral point leads to?
There are mainly two kinds of motor connection, star connection and angle connection two kinds. - star connection is 3 at the end of the three-phase coil motor connected together as a common, common end is neutral.Angle connection -- is to each phase of the three-phase motor through the coil ends are orderly connected with the connection.      Three phase winding motor is completely into the end cover is connected, the end cover has six heads, three heads below together, the above three heads respectively leads to the three line is the star connection; the upper and lower two head vertical connection, respectively leads to the three line is connected with the triangle.
Q:Why is Tesla's Model s electric vehicle using AC motor instead of the more popular frequency conversion DC motor?
1, the DC motor structure is complex, the cost is relatively high, late maintenance trouble.2, larger motors are required to be connected to large cooling fans.3, it can realize the speed regulation simply and economically. Big torque and good mechanical characteristics.4, AC motor structure is simple, low cost, simple maintenance. You can't speed it yourself. In the past, the frequency conversion was not timely, and the DC motor was used in places requiring good speed control (machine tools, cranes, textiles, etc.).
Q:How many kinds of braking modes are there in AC motors? What are the characteristics of each?
Energy consumption brakingWhen the motor cuts off the AC power supply, a DC power supply is added to any two of the stator winding to generate a stationary magnetic field, and the stationary magnetic field is generated by the inertia rotation of the rotor to produce a braking torque
Q:The difference and advantage between DC motor and AC motor
DC motor:Advantages: 1., you can achieve a smooth and economical speed adjustment;2. does not require the coordination of other equipment, as long as the input or excitation voltage, current
