Factors to Consider when Choosing Variable Frequency Drives

A variable frequency device in short form VFD is referred to as a device that is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor and a variable frequency drive can also be referred to as a variable speed drive. It is important to know that there are several factors to consider when choosing a variable frequency device for an electric motor.

The following factors that have been listed below shows the consideration of factors that are to be followed when choosing variable frequency drive.

Altitude as a factor considered when choosing saint louis variable speed drives has an effect on cooling which when the air becomes less dense the altitude increases this decrease in air density decreases the cooling properties. It is important to note that most of them operate at 100%. It is important to know that at higher altitudes the Frequency Drive must compensate for a decrease in cooling for the air to become less dense.

Another factor to consider when choosing a variable frequency device is temperature. Temperature in the AC drives is an important factor to consider because it generates a significant amount of heat and can cause internal temperature of an enclosure to exceed the temperature rating of the Frequency drive this may require a ventilation or cooling to control the temperature. Be sure to view here for more details!

Another factor to consider when choosing a variable frequency drive is overload. Therefore, overload is the ability of a frequency drive to handle all conditions. One should note that overload is an important factor to consider to be sure if the variable frequency drive can handle an overload of conditions. An overload can be greater than 150% or longer than 60 seconds. It is also important to know that in the overload factor the constant or variable loads frequency starts and stops or rather operations must also be considered when selecting the frequency variable equipment or variable drive.

The application type of a variable frequency drive should be considered when choosing one. Thus, there are two major types to consider when choosing a drive. One of them is the constant torque(CT) and the other one is Variable torque(VT) in which both have its ratings One must be aware of the two types of applications which include constant torque and variable torque which each of them had its ratings. The application type is very important in this choosing of the frequency variable drive because each of the two different drives are specified accordingly with no mix-up. The constant torque is most recommended when one person is not sure of what to buy between the two application types thus when choosing a variable frequency drive the security can be directed to the constant drive as the most commonly used . Therefore, in the ratings for the conveyors and general machine control, the variable torque is mostly us as the application type.
