Selection of Variable Frequency Drives – Examples
The equations for calculating the power requirement for VFD has been discussed in Selection of Variable Frequency Drives. Using the equation below, we will provide some examples on selecting a …
Selection of Variable Frequency Drives
The size of a variable frequency drive (VFD) should be based on motor voltage and current and not on the torque or power rating. The voltage and full load current …
Variable Frequency Drive Cable Length Resonance Frequency
This is a continuation of the article Effect of Cable length on Variable Frequency Drive. Cable Resonance When dealing with Variable Frequency Drives (VFDs), the cable length between the VFD …
Effect of Cable Length on Variable Frequency Drive
Every cable has, apart from its resistance, certain inductance and capacitance. The inductance and capacitance is roughly equally distributed along the cable length. Inductance L and capacitance C in a …
Variable Frequency Drives Cable Selection
Variable frequency drives (VFDs) also known as variable-speed drives or adjustable-speed drives are used to power 3-phase AC electric motors in applications requiring greater control and power efficiency. The benefits …
