Reliable VFD Reactor for Motor Protection

Frequency inverter is critical in motor control applications, enabling precise speed regulation and energy efficiency. However, the high-frequency switching signals generated by VFDs can induce voltage spikes, electromagnetic interference (EMI), and motor insulation stress, especially in long cable runs or high-power systems. To address these challenges, ​iac line reactor or input choke for vfd ​ (installed on the input side) and ​vfd reactor​ (applied to the output side) are essential Inverter Components that enhance system reliability, protect motors, and ensure compliance with electromagnetic compatibility (EMC) standards. This technical guide focuses on ​vfd reactor, their design, functionality, and applications, with a comparative analysis of ​input choke for vfd. 1. Overview of AC Reactor  ​ A ​VFD reactor​ (also called an output reactor or output choke) is an inductive device placed between the VFD and the motor. Its primary role is to suppress voltage transients, dampen high-f…
