Abramowitz Phase-Control Alternatives for Single-Phase AC Motors Offer Smart, Low-Cost, Solutions by Howard Abramowitz, EE , President, AirCare Automation Inc. Abstract - single Phase AC motors continue to be the primary solution for air-movement, pumping and compressor applications. Their low cost and availability make them ideal for low-performance systems. DC Brushless platforms attempt to address these applications but their higher cost and complexity continue to form impenetrable barriers of entry. They are viewed as overkill for most applications. Single-Phase Inverter Drives have come on the scene, making headway, but remain complex and costly.
