Can the engine regulator block U F be adjusted?

It should be possible to adjust it, because such an engine regulator block is such a function, and it can be adjusted a little more.

So it should be okay.

Generally not, u f regulation is simply voltage and frequency regulation. Voltage regulation achieves the purpose of adjusting by changing the DC voltage of the excitation circuit, and increasing the excitation voltage can increase the output voltage of the generator.

Frequency regulation is achieved by changing the rotational speed, increasing the rotational speed and increasing the frequency rise.

Yes, if there is a problem, it can be adjusted, it is recommended to find a manufacturer.

The stabilizing block cannot be adjusted, as it is mainly engine-dependent. mass and the efficiency of the engine's work, so it is not possible to adjust these things.

Hello, this one can be adjusted. You call the after-sales customer service, and they will arrange personnel to come to the repair.

It should be adjustable. just, but you can't adjust it casually, which will make the engine. Instability.

No, unless you buy a new one, don't mess with this thing.

Of course, the UFO of the engine regulator block can be adjusted, and its adjustment efficiency is also relatively good, which can better carry out some practical things.

The generator can be adjusted for briquetting, and if it cannot be adjusted, it should be solid.

His voltage regulator can definitely be adjusted, and in general, there is a corresponding adjustment program, which can be directly adjusted to some data you need.

Of course, the voltage stabilization of the engine can be adjusted, if the pressure is not enough, if it is unstable, it will not operate normally.

Personal and portable electronic products are constantly innovating, and the pace of development is completely consistent with Moore's Law. comparatively. One of the back-end technologies is peripheral active circuitry

This cannot be adjusted, because the manufacturer has already set it up when it leaves the factory, and if it is adjusted, it is necessary to communicate with the manufacturer.

Can the engine regulator block have a bar f that can be adjusted? I think I can adjust this engine.

The engine regulator is not adjustable.

The voltage stabilization module of the engine should be adjustable, right?

First of all, the size of the input electric power of the motor is not directly related to the frequency, the size of the output power is related to the frequency, because the frequency drops, the speed also decreases, if the load torque remains unchanged, the output power must also decrease. How does the motor convert from the input of electrical energy to the output of mechanical energy? Originally, the rotor winding induces an electric current due to the cutting of the magnetic field lines of the rotating magnetic field, and the generated current interacts with the magnetic field to generate electromagnetic torque, which makes the rotor rotate.

Obviously, it is the magnetic field energy that plays the role of energy transfer and conversion in the middle, and its power is called electromagnetic power, which is expressed in PM. The embodiment of electromagnetic power is the magnitude of magnetic flux. When the frequency drops, the speed of the motor must also decrease.

As mentioned above, the input power of the motor has no direct effect, but the output power is reduced. As a result, there must be an increase in electromagnetic power. It's like a person who eats a lot, but doesn't move much, consumes less, so his belly grows, and people often jokingly call it 'the rise of the middle'.

But people's 'rise in the middle' is mainly because of their ugly size, and they are not going to die immediately. The 'middle rise' of the electric motor is internal, the "size" has not changed, it will not get fat, however, it will smoke and will not live. The main factor of heat generation is electric current.

Although the magnetic flux increases, the eddy current loss and hysteresis loss will also increase, but not to the extent of smoke. The problem is that the magnitude of the magnetic flux will affect the excitation current, and the result of the 'rise in the middle' of electromagnetic power is that the magnetic circuit is saturated, the excitation current increases significantly, and distortion occurs, so the windings will smoke. In the final analysis, it is the current that causes the windings to heat up.

The main factors of input power are voltage and current. The current cannot be reduced, because the current is used to generate electromagnetic torque, and if the electromagnetic torque is small, it will not carry the load. So, the only way to 'eat less' is to lower the voltage.

The inductive reactance of the motor coil is related to the frequency, the frequency is low, the inductive reactance is small, at low frequency, according to Ohm's law, the voltage is certain, the inductive reactance is small, the excitation current must be large, the motor is seriously heated, and the motor shows a decrease in torque.

Basically, the power will be constant, and the current will be very large when starting, and it will generally fail.

U f control is the frequency ratio of the frequency converter speed regulation, which is generally a constant. In order to control the stator winding current, when the frequency is reduced, the voltage must also be reduced when the frequency is reduced.

Sometimes variable voltage is required and sometimes not required, depending on the actual situation. For example, inductive loads may need to be transformed, because the impedance of the inductor is different at different frequencies, and transformer is required for constant power.

The classification is classified according to the working mode of the main circuit, which can be divided into voltage-type inverter and current-type inverter; According to the classification of switching methods, it can be divided into PAM control inverter, PWM control inverter and high carrier frequency PWM control inverter; According to the classification of working principle, it can be divided into V F control inverter, slip frequency control inverter and vector control inverter, etc.; According to the classification of use, it can be divided into general-purpose inverter, high-performance special inverter, high-frequency inverter, single-phase inverter and three-phase inverter.

The so-called U F voltage compensation, in fact, is the volherherfield limit, which is a limiting function designed to avoid overexcitation of the generator or the transformer connected to the generator. Usually u f = constant, that is, the ratio of the voltage standard value to the frequency standard value is a constant in the limit section, and the ratio of most regulators is 40-47Hz in the limit section. When the generator frequency is lower than the lower frequency, the excitation regulator will issue a command to invert demagnetization, that is, low-frequency protection.

The speed equation of the asynchronous motor is n=60f(1-s) p, where n is the number of revolutions of the motor, f is the frequency of the power supply, s is the slip rate, and p is the number of pole pairs of the stator rotating magnetic field, so it can be seen from this formula that if you want to change the speed of the motor, you can change any one of the three quantities f, s, and p, and you can achieve speed regulation, among which changing the power frequency f is a more convenient and effective method (I won't talk about why specifically), As long as you change the frequency of the power supply f, you can change the speed of the motor, but there is another problem, let's take a look at the following formula.

U=E=, where U is the power supply voltage, E is the induced electromotive force of the stator winding, F is the power supply frequency, N is the number of winding coil turns, K is the winding distribution coefficient, is the magnetic flux, from this formula we can see that if f is reduced, the power supply frequency U is still unchanged, then it will inevitably become larger, because the magnetic circuit design of the motor is designed according to a certain magnetic flux, if it increases, then the magnetic circuit may enter the saturation state, so it must be guaranteed to be constant, so the corresponding power supply voltage U should also be reduced, In the same way, if f increases, u also increases, and we must ensure that u f is a constant.

Vector control is a complete analog vector to achieve the purpose of control, UF is much rougher and limited and the hardware can not adjust the voltage very much, in short, in the case of low frequency and high torque, the general vector is better.

U f ratio (torque compensation) is larger, that is, in the low frequency band voltage increases, less than the increase in torque, high voltage, also consume more power, in the case of meeting the air volume, below 50Hz, U f ratio is smaller and more power-saving.

The low torque of the inverter at low speed is a method to increase the low frequency range f u in order to compensate for the decrease in torque at low speed caused by the resistance of the stator group of the motor. When the magnetic circuit is saturated at low frequency, the initial voltage can be appropriately increased to compensate, pay attention to the actual situation to improve, do not set too large, otherwise it is easy to cause the overcurrent protection of the inverter.

At low frequencies, low voltages are output, and the voltage drop across the rotor line resistance causes insufficient torque.

V f control mode, because it cannot be self-learning, can not collect the electrical parameters of the motor, so can only choose different V f control characteristic curves to control the motor. It is not possible to accurately adjust the motor torque compensation and adapt to torque changes. In order to have high control accuracy, the vector control mode should be selected, and the inverter with motor self-learning should be carried out to correctly collect the electrical parameters of the motor.
