When converting a three-phase induction motor into a generator, correctly sizing the capacitors is crucial to ensure efficient operation. Capacitors are used to offset the inductive characteristics of the motor, improving its power factor and overall efficiency. If you're wondering, “What size capacitor should I use?”, this guide will walk you through the process of determining the correct capacitor size for your generator conversion project. In this tutorial, ATO industrial automation will explain what ‘capacitor size’ implies and provide you with all necessary formulas and important considerations you would need to figure it out yourself.
