Brushless dc motor controller is used in heating belongs to the normal phenomenon, but has the certain control. Some users find fever just feel there is a problem, in fact, the cause of the fever we can from several aspects to understand. One, the coil resistance, electric current flows through the loss power; Second, the core of magnetic hysteresis loop, part of the electrical magnetic energy is to continue to heat energy; Three, core and eddy current, the electrical part of magnetic energy and into current in turn into heat energy; Four, mechanical friction between moving parts, part of the kinetic energy of the electrical continue into heat energy. Brushless dc motor controller fever - 7090 ℃ belongs to the normal phenomenon, as long as less than 130 ℃, generally do not have what problem, if you really feel overheated, sent the current set of drive motor controller is about 70% of the rated current or the speed of the motor controller is lower. No fault, under normal circumstances will be hot. Of course, the normal heating temperature not too high. To understand the causes of fever brushless dc motor controller, we can reasonable control. If the temperature is beyond the normal range, so should be in time to stop working, and makes the corresponding inspection work, and do the processing. Small make up: Sara
