Improving Performance and Cost inSingle-Phase AC Fan Systems

摘要

Single-Phase AC motors continue to dominate the motor market and continue to grow involume. Their low cost and simplistic design make them an ever favorite even as they areslowly displaced with more complex; more energy efficient solutions. By utilizing digitalcontrol technology to the more basic single-phase AC drive, many improvements can bemade to the performance, noise and installation costs related to these motors. Fanassemblies are becoming more common in both distributed HVAC systems andCleanroom filter systems. The low cost AC platform will continue to play a significantrole and with improvements resulting from digital control we can narrow the performancegap. Thus, the AC systems will be quieter, more efficient and easier to install; extendingtheir usefullness and competitiveness for new applications and installations.
