Dc motor controller at work, sometimes because of certain factors of be affected with damp be affected with damp. For these situations, we how to deal with? Below small make up for it. 1. Excitation coil drying: used in gear motor controller on the stator iron core coil excitation coil, and then pass into the alternating current, the stator flux, depend on the excitation coil to dry deceleration motor controller of the stator. 2. Electric welding machine drying method: first of all need to be affected with damp be affected with damp reduction motor controller winding connection head together, then chassis grounding, thus to achieve three sets of winding heating dry. Above is about dc motor controller's handling of be affected with damp be affected with damp, hope to help you.
