Importance of Using Variable Frequency

Energy and maintenance cost can be reduced by making use of variable speed drive especially in AC motor. View here for more information about AC motor.

Firstly, when you use variable speed drive, the energy consumption of your machinery reduces substantially. Variable frequency drive is helpful especially in cutting down the amount of energy consumption for running centrifugal load operations. If you take an example of a pump or a fan whose speed is half of the normal speed can be brought down by the factor of 8. The method of reducing energy expenditure is by minimizing the energy consumption of machines and tools using variable frequency drive.

You can also benefit from reverse operations when you use variable speed drive. Motors which are equipped with variable frequency drive does not require reverse starters since they are fitted with an electronic switch which can output reverse operation. Simplicity and lower cost of maintenance makes variable speed drive a better option as compared to reverse starter. Another advantage of electronic reverse switch found in variable speed drive is that they are much smaller in size and conserve the space that could have been occupied by reverse starter.

With variable frequency drive, you will have the ability to control the starting current. A current of between seven to nine times is required to initiate AC motor to full-throttle and get the load and motor started. The advantage of variable speed drive is that it improves the longevity of AC motor because the amount of current for starting AC motor is small.

The problems that are normally brought about by the power line can be averted by using variable frequency drive. These two issues normally cause the sagging of the power which then cause problems to other equipment connected to the distribution such as computers and sensors. The ability of the variable frequency drive to control current can help to avoid the sagging of the power line which brings issues to other devices.

The controlled speed-up process is another benefit that you stand to gain by using a variable frequency drive in your vehicle. AC motor and other devices linked to the distribution often experience mechanical problems such as mechanical shock, especially during the startup process. Mechanical shock normally causes a lot of damage to many devices like computers, sensors, and other electronic devices. With variable speed drive, the startup process is normally slow and smooth preventing issues like mechanical shock which in turn improves the longevity of AC motor and other devices.

Variable frequency drive can be used to adjust torque limit. Torque limit adjustability helps the variable speed limit to control all the machinery process and in turn protect them. The process of adjusting torque limit is through programming which is done by the variable speed drive. Energy conservation is also possible using variable speed drive which in turn cut down the total cost expenditure of energy.

Another advantage of using variable frequency drive is that mechanical drive component is not required. The speed-varying device is not necessary because speed frequency drive have the ability to control the speed for each and every application. When you opt for varying speed drive, you do not need the gearbox which is costly to purchase and maintain.
