What Are You to Consider when Choosing Frequency Variable Drives
A variable frequency is a type of motor that drives moto by varying frequency and voltage. 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 a variable 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.
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 be sure that the frequency variable drive can handle any overload conditions when choosing one. It is important to know that an overload can be greater than 150% or rather longer than 60 seconds which is an hour. frequency is the one that leads the overload factor.
The application type of a variable frequency drive should be considered when choosing one. There are two types of frequency variable drive. It is important to know that there are two types of frequency variable drives. One must be aware of the two types of applications which include constant torque and variable torque which each of them had its ratings. It is important to know that the application type because the frequency variable drives are organized accordingly as per the two types mentioned above. It is important to that if one is confused or rather doesn’t know the application type to choose, it is most recommended that he or she chooses the constant torque as it is mostly used. The variable torque application type is used for the conveyors and the general machine control.
