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. Therefore it is a type of motor controller that should drive an electric motor by varying the frequency and voltage supplied to the electric motor.
Some of the things one needs to consider when choosing a variable frequency drive.
It is important to know that altitude affects cooling thus is a factor to consider since when it increases the surrounding air becomes less dense and therefore this decrease causes the air density to decrease the cooling properties. The altitude in variable frequency drives operate at 100% in most of the frequency variable drives. At high altitudes the driver must compensate for the decrease in cooling for the air to become less dense.
It is important to know that temperature is also a factor to consider when choosing a variable frequency device since temperature in a variable frequency device generates a significant amount of heat to the motor therefore can cause internal temperature of an enclosure to exceed the temperature rating of the Frequency drives this a ventilation or cooling may be required to control the temperature of the motor. 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. It is important to know that overload refers to the number of conditions that one frequency hard drive can handle, considering all the conditions encountered. It is important to know that when choosing a frequency variable drive that one should be sure that the drive can handle any overload conditions. An overload can be greater than 150% or longer than 60 seconds. frequency is the one that leads the overload factor.
It is important to note that the application type of drive is crucial to consider when choosing a frequency variable drive. It is important to be able to name the two types of applications which include constant torque and variable torque of which both have separate 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. Therefore, when choosing a frequency variable drive, one should know that each application type has its specifications thus avoiding any confusion or mix-ups. 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 . It is important to know that the variable torque is mostly or rather commonly used in the ratings of the conveyors and machine control.
