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 VFD for a specific motor. Note:These motors are used for electric submersible pumps hence the voltages are different from the usual motor ratings. [pmath]P_IN = {sqrt{3}*V_motor*I_motor*PF_motor}/{{eta_VFD}*{eta_motor}}[/pmath] 1. For the 150HP motor...

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 information can be taken from motor nameplate or datasheet. [caption id="attachment_18665" align="aligncenter" width="640"] Induction Electric Motor Nameplate[/caption] While the motor can be rated...
