"Blower Fan" early stage of development, according to the original view, miniaturized servo motor has reached its limit. Therefore, we are not relying solely on the servo motor, but a modular, to achieve a substantial miniaturization. Servo motor drive damper must rely on the drive circuit and wiring harness. In the past, each requires a separate servo motor drive circuit and wiring harness. The three new HVAC embedded servo motors, on this basis, developed a drive circuit harness integration module. Servomotor by the Group's E Simo (Headquarters: Shizuoka Prefecture Kosai), servo motors in HVAC mounting portion and the driver circuit according to the company's hot design division, electronics division made by, brought together "all the inside and outside of the company wisdom and strength".
