Q:The laptop's power adapter is too hot to do
The original adapter heat should be no problem, the fan mouth is very hot, the weather may be more and more hot it!
Q:Can the inverter stop intermittently during operation? If so, how to connect and set up
Look at your inverter manual, because the inverter is not a simple wiring can run, first of all have to know that a few are external terminals (inverter input terminals),
Q:Is the laptop power adapter high temperature normal? Is there anything else?
Normal, my power adapter is also very hot, generally ignore
Q:Will the 75KW4 pole motor can be used to increase the speed of the inverter?
Can not, only slow down, on our national grid, 50HZ is the largest. At least with the inverter can not be achieved.
Q:Master Hello a machine requires 500 speed matching 6-pole motor frequency converter transferred to about 28HZ
The belt rotation is calculated by the speed ratio. The current transferred to the motor by the inverter is approximately equal to the rated current of the motor, ie the motor's power is maximized.
Q:B2b frequency how to speed
AC motor speed control methods are four: frequency, transformer, variable pole and winding motor to change the rotor loop resistance of the speed control method. Its source is based on the motor speed formula: n = (1-s) * 60f / p where: n --- motor speed s --- motor slip f --- power frequency p --- motor pole Logarithm
Q:Will the asynchronous motor pole change the number of speed control can also be combined with the frequency converter
but the use of the inverter is based on changes in the load by changing the frequency of power into the motor at any time speed control, you can achieve a smooth and accurate stepless speed control is Now widely used in a speed control method, especially for the load often change or often in the light load operation of the motor.
Q:What is the motor series parameter setting of the inverter? If it is with the spindle,
The motor series setting of the inverter should be set according to the series of motor
Q:Can the laptop 1.3a power adapter be used on a 1.5a device?
Theoretically impossible, because the power is small, but if it is a short period of time is possible, a long time to die.
Q:What is the IGBT? Our inverter IGBT fried,
Name is the FET, the price of this thing is more expensive,
