"Blower Fan" small blower, modular servo motor to minimize side area made a major contribution. First look at the development of small blower. Action blower cold or warm wind is blowing towards the car. Miniaturization Needless to say, in order to meet fuel efficiency regulations, the need to reduce power consumption. Quietness must also be improved. This is because being popular with idling stop cars and HEV engine body sometimes is stopped, the engine noise will become apparent from the outside. To reduce fan noise, using common sense is a big fan of slow turn, but miniaturization and contradictions. So we boldly use small fans at the maximum efficiency of the motor rotates at high speed and then take measures to reduce operating noise.
