Motors are used for various purposes without being seen by the general public, and there are a huge number of them. For example, many motors are used in automobiles, reportedly with about 50 motors for an average car model and about 130 motors for a luxury model. In the case of air conditioners, motors are also used for compressors, the fans of indoor and outdoor units, and electronic expansion valves, etc. The motors adjust the rotation speed of the compressors and fans of the indoor and outdoor units, according to the load of the air conditioner, creating a large power consumption reduction effect. In particular, the number of motors required for the fans of the indoor and outdoor units is enormous, making them an important target for energy savings along with motors for compressors.
