Q:Is the motor having a variable frequency motor and a variable voltage motor?

It should be no change it is the input / output current is v frequency is its input / output frequency is M / Hz

Q:Does the inverter set the number of poles to match the number of poles of the motor?

The number of motor poles corresponds to the speed of the motor, the number of poles is not set when the speed of the control error, in the high speed requirements of the transmission is not allowed.

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:On the notebook power adapter output current and voltage issues

On the real virtual cable that adapter is rectifier filter output, no regulator, the notebook internal regulator, the adapter does not need to regulator. 3.25A is smaller than 4.5A, because the adapter has a power margin that can be used. Summer attention to touch the adapter surface is overheating. Conditional or buy a large number of good current.

Q:2 pole 0.75 kW motor can increase the speed through the inverter?

2-pole motor speed of about 2900 r / min or so, 4-pole motor speed of about 1400 r / min or so, which are in the case of 50HZ,

Q:Delta VFD-F frequency converter how to adjust the number of poles

P148 look, this is to correspond to the number of poles of the motor, not to adjust the number of poles of the motor

Q:How to learn the inverter debugging and design parameters

You can find the basic inverter manual, see a few times to try, under normal circumstances, the inverter on the use of manual functions such as research to understand that most of the applications are no problem.

Q:East yuan 7200GS inverter start 11KW 4-pole motor and 2-pole motor need to modify what parameters?

motor to be slightly larger, the speed of 4 pole speed is 1450 r / min, 2 pole is 970 r / min The With the inverter control, you only need to modify the parameters of which the motor parameters, and then the motor parameters from the study on it, the most important is your use of inverter equipment and control methods, and then the above two factors Feature adjustment parameters. There is to pay attention to the use of the inverter environment, the inverter is an electronic product, the environment is relatively high, in the use of as much as possible to improve the use of the environment.

Q:Will the 75KW4 pole motor can be used to increase the speed of the inverter?

can! The output frequency of the inverter is higher than 50HZ, the speed of the motor is higher than the rated speed. In a certain range, the higher the frequency of the inverter, the faster the motor speed.

Q:Laptop power adapter current is not the same alternative?

so the output voltage, the same output polarity, the output current of the adapter can be used in smaller power notebook, and small power adapter can not be used to give Powerful notebooks,
