AC Drives are devices for controlling motor speed by converting DC to AC. The emergence of AC Drives has improved productivity spectacularly and made a huge contribution to the development of the industry. Further, AC Drives have brought about a substantial change to our lives. For example, airflow from air-conditioners and fans can be regulated by changing motor speed. Thanks to AC Drives, we can keep a room at a comfortable temperature even in the hot summer and cold winter. The regulated airflow also reduces energy consumption, contributing to energy conservation. Yaskawa’s AC Drives are adopted in a lot of large-scale office buildings such as Roppongi Hills and Marunouchi Building.
Motor speed can be freely changed.
Soft start/stop function
Can standardize machine
Can minimize power supply capacity
Rotation direction can be easily changed.
You can not change motor speed and need to regulate airflow by using a damper (on-off valve). Even when you reduce the airflow, the amount of electricity used would not substantially change.
Motor speed can be freely changed. For fans and pumps, greater energy-saving effects can be achieved.
As a conveyor suddenly moves, loads can fall on impact.
Soft start/stop can be performed. Start and stop are smooth and become a motion gentle to a luggage.
You can not change motor speed and have to adjust the speed by using a pulley.
Take some effort to move…
Can standardize machine
Adjustable to both 50Hz and 60Hz power supplies with AC Drives
