FAQ

The laptop power adapter is burned

You this situation or the first adapter to try, it is likely that the adapter power shortage. If you change the adapter or so, then your problem is big, there may be your laptop to protect the isolation circuit and the charging circuit is a problem, in the insurance repair is free, if the insurance, and to be afraid of a little fear Small expensive, the adapter to buy a cottage on the line, as long as tens of dollars.

Is the speed of the motor controlled?

Slip motor is composed of ordinary squirrel cage asynchronous motor, electromagnetic slip clutch and electrical control device composed of three parts. Asynchronous motor, the stepper motor is used as the prime mover, and when it rotates, the armature of the clutch is rotated together. The electric control device is a device that provides the excitation current of the slip clutch excitation coil. Electromagnetic slip clutch, which includes armature, magnetic pole and excitation coil three parts.

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,

Power will drop, down to the original one-tenth

What is the motor series parameter setting of the inverter? If it is with the spindle,

Ordinary inverter standard drive is a 4-pole motor, the greater the number of poles of the motor, the greater the rated current, the motor pole number is the frequency converter when the self-learning automatically set, in the vector control must be self-learning

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

if the 4-pole motor to rise to 2-pole motor frequency, The frequency of the motor rises to about 100 Hz, which is easy to implement for the frequency converter.

Laptop warranty period is not over, the power adapter is broken, repair money?

Look at your reinsurance period if not in the warranty period is not man-made damage can be changed or for the change

What is the IGBT? Our inverter IGBT fried,

Basically change the voltage, the voltage changes in accordance with the different frequencies, so that change the speed.

Who knows how the frequency converter works

3. Control circuit Now the basic converter with 16-bit, 32-bit microcontroller or DSP as the control core, in order to achieve full digital control. The frequency converter is the output voltage and frequency adjustable speed control device. The circuit that provides the control signal is called the main control circuit. The control circuit is composed of the following circuits: "operation circuit" of frequency and voltage, "voltage and current detection circuit" of main circuit, and "speed detection circuit" of motor. The control signal of the operation circuit is sent to the "drive circuit" and the "protection circuit" of the inverter and the motor Inverter to take the control mode, that is, speed control, turn control, PID or other means
