AC Drives


Maximize your operational efficiency with high-performance AC Drives, the intelligent "brains" of the modern industrial motor system. By precisely controlling motor speed and torque, these drives eliminate the waste of traditional fixed-speed operations, delivering massive energy savings and superior process control. Beyond the bottom line, AC Drives protect your equipment through "soft start" technology, significantly reducing mechanical wear and extending the lifespan of your critical assets—from HVAC fans to heavy-duty manufacturing conveyors. Invest in precision, sustainability, and long-term reliability for your facility today.

At AFi Systems we offer comprehensive support for all kinds of AC Drives. From Siemens to Parker, Yaskawa to Hitachi, or ABB to Allen-Bradley, we can service drives from a plethora of different vendors. Requests for refurbished, new surplus, or factory-new articles can all be accommodated, and our expert team with over 350 years of combined technician experience are primed to handle both in-house and on-site repairs for any units requiring service with quick turnaround times using state-of-the-art testing equipment. Boasting a no-fix, no-fee policy and a two-year warranty for all repairs, we at AFi Systems take pride in our work, and will always endeavour to ensure your satisfaction.

Any refurbishment includes the replacement of any components likely to degrade over time such as electrolytic capacitors and electromechanical parts like cooling fans, before being soak tested in one of our dedicated drive bays so we can be confident in our two-year warranty. Our refurbishment services include drives for obsolete products whose legacy fieldbus communications prohibit easy retrofitting.
