The most important consideration when choosing a Variable Frequency Drive (VFD) is to know the type of load that is being applied to the motor because it will determine the size and cost of the VFD. The VFD must have sufficient current capability so that the motor can produce the required torque for the load. KB Electronics offers VFDs for AC induction, Permanent Magnet Synchronous Motors (PMSM), and Brushless DC (BLDC) motors that can operate efficiently for various types of loads.
