FAQ

Will the asynchronous motor pole change the number of speed control can also be combined with the frequency converter
Of course, because the factors that determine the speed of asynchronous motor power supply voltage, frequency and motor pole pairs, so asynchronous motor speed can be achieved by changing the number of magnetic pole pairs, but this method needs to make a greater motor changes, Trouble, and change the number of poles can only achieve a single speed change;
380V 2 pole motor can use the inverter?
At the same time, the paint is thick, the best 2 times dipping Wiring with the end of the enameled wire end of the time, to use insulating materials separated better, more insurance
Notebook plug in the power adapter lights, but can not open the machine
1. Remove the power adapter and battery, the host does not power the case, hold down the boot button does not move, keep the notebook 30 seconds to release the residual static electricity; 2. Connect the power adapter separately to try to power on; 3. Connect the battery separately to try to boot; 4. If conditions permit, you can plug the memory test.
How to choose a power adapter
With the seller to an output 20V ,, 0.5A IBM single hole power adapter
Laptop power adapter aging
This should be no, play the game automatically shut down should be detected other
With the inverter control fan 37Kw4 pole with what model inverter
Control the fan: select the fan pump with 37KW or 45KW inverter.
Can the inverter be used to control the speed of the DC motor?
For the brush commutation DC motor, the speed of the output torque in a certain circumstances and the input voltage related. For this type of motor, use the inverter to control the output of the rectifier device that supplies power to the motor, which can control the speed. For the brushless DC motor, the controller is in accordance with a certain law to change the form of stator winding power supply to produce a rotating magnetic field to drive the rotor rotation. That is, the DC motor controller outside the part of the AC motor and the structure and the principle has not much difference (see below. For such motors, with the inverter to replace the controller, and control the same as the AC motor Control the speed.
The parameters of the inverter is 4, 6 motor can be used
Variable-frequency (VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment.
