Q:Is the motor having a variable frequency motor and a variable voltage motor?
Motor with DC and AC motor, variable frequency motor and fixed frequency motor, string motor, that is, I have not heard of a transformer motor.
Q:The motor is 2 pole with the inverter frequency to 50hz why the speed is only 1500 rpm
The speed displayed on the display may be the speed of the deceleration or transmission. It is also possible that your inverter parameter ratio is not set, you need to modify and adjust, you want to help.
Q:I have a 5.5 kilowatts of 4-pole motor, want to pass through the inverter, slow down to 130 per minute use, eliminating the need for speed,
Second, the use of low-speed inverter motor. Ordinary motor running for a long time, heat is certainly not work.
Q:Siemens g120 inverter torque limit what is the meaning
Torque is a strain, the inverter can not actively control the output torque size, only according to the size of the load demand torque, the output of the corresponding torque.
Q:What is the difference between variable frequency motor and variable speed motor?
The variable frequency motor requirements are high, are special motor, so the general motor can not use the inverter to speed. According to the above formula, it can be seen that increasing the frequency, the motor speed will be faster, reduce the frequency of the motor speed is slow, variable frequency motor core is also a special material, because the ferromagnetic material There is a saturation period, to the saturation period, regardless of whether the motor current increases, the motor will not continue to increase the intensity of the magnetic field,
Q:Can the notebook's power adapter be mixed?
In general, the same brand of notebook power adapter, as long as the same wattage, the same interface, can be mixed with. But do not recommend different brands or different wattage power adapter mix. Because the output wattage is different, there may be damage to the notebook, such as voltage instability and so on.
Q:Why the number of motor poles increased, the inverter capacity will increase
The power of the three-phase motor is equal to the root number of 3 times the line current and the line voltage of the product again good with the power factor. Can also be 3 times the phase current and phase voltage of the good product and then good to power factor. The frequency converter should match the rated current of the motor, not the power of the motor.
Q:Old printing machine transformation, 37KW6 polar frequency motor with brake, inverter 55KW, now found running,
It should be the inverter problem, I have encountered before, followed by the inverter upgrade was resolved. Is to replace a set of power board, power board, CPU board.
Q:Variable frequency conversion frequency difference characteristics based on,
Frequency conversion is better, you can smoothly change the synchronous speed. Change the difference is relatively poor, also known as "energy consumption slip" speed. Synchronous speed unchanged, the slip rate has changed, so the speed changed.
Q:Computer frequency changer to do cd frequency changer how points positive and negative
This inverter is 380V of the bar, the capacitor series is to increase the pressure, and then parallel to increase the capacity of the capacity of the capacitor and the inverter is proportional to the power, the greater the capacity of the capacitor capacity requirements are greater.
