FAQ

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.

What is the frequency converter used to do, why some motor with the inverter?

Speed control, there are speed requirements of the place are in the inverter

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.

The inverter is running independently

Principle of operation The main circuit is to provide asynchronous motor to the frequency conversion power supply part of the inverter, the main circuit of the inverter can be divided into two categories: voltage is the voltage source of the DC converter for the exchange of the inverter, DC circuit filter Is a capacitor. Current type is the current source of the DC into AC inverter, the DC loop filter is the inductance. It consists of three parts, the frequency power supply is converted to DC power "rectifier", absorbing in the converter and the inverter voltage ripple "smooth circuit." The basic composition of the rectifier unit: the fixed frequency of alternating current converted to direct current. High capacity capacitance: store converted energy. Inverter: high-power switching transistor array composed of electronic switches, the DC into different frequency, width, amplitude of the square wave. Controller: According to the set program work, control the amplitude of the output square wave and pulse width, so that superimposed as an approximate sine wave AC, drive AC motor.

How to lift Yaskawa inverter base blockade?

Note: the base blockade is to deal with ul or ce such a special application of security agencies, meaning that when the parking limit action after the base blockade even if the program can not malfunction, relative to the emergency stop loop more harsh, they will directly cut off the power power supply. In fact, it is a white protection function, if we are not difficult to find the analysis, when over-voltage or undercurrent, the panel will show BB alarm, BB is the base block, is the base blockade.

What is the base blockade in the drive?

Normal work, the bridge between the upper and lower pipes can not be turned on at the same time, while conduction will occur short-circuit accident. It is necessary to open a tube at the same time block the same bridge of the other pipe base can be safe to work.

Laptop power adapter output voltage is not the same as the current? What's the effect?

so this replacement is generally feasible in the general use , But the remaining power supply power margin is very small, once your books took a lot of peripherals, such as two usb hard drive, and then cpu full speed operation, and then a base, the above to drive a full speed to read the disk, plus While charging the battery, it is estimated that the danger, and at any time to touch your power is not already already boiled eggs. 72w more than the 56w adapter 16w is to cope with this situation. So it is best not to use a small current instead of high current power supply

Why the notebook power adapter can not be universal

Second, the voltage is different Different brands of laptop power adapter voltage is not the same, for example: under normal circumstances IBM is 16V, Dell is 20V, Hp is 18.5V, Sony is 19.5V and so on. Thus, even if the power adapter interface is the same, can not use different brands of laptop power adapter for power supply.
