Appropriate countermeasures against back-EMF are essential, particularly in fields that require high reliability, such as medical equipment and industrial equipment. By correctly understanding the principles behind back EMF and grasping its specific effects on motors and power supplies, you can incorporate effective countermeasures from the design stage. To achieve safe and reliable product designs, let\u2019s deepen our understanding of back EMF."}
