The Drives & Motion Division of Yaskawa America, Inc. (Waukegan, IL) has expanded the Single Phase Converter (SPC) product line up to 125 HP at 460V and 60 HP at 230V. The SPC converts single-phase power to DC power for use by Yaskawa variable frequency drives. The SPC is the solution to the biggest problems facing business owners that power medium sized motors in rural areas. They can be faced with high costs to run three-phase power, limited single-phase motor options and a wide range of quality issues.
Enabling rural applications such as agriculture, lumber mills, oil & gas, and pumping to utilize three-phase variable speed control offers a host of new possibilities to their businesses. Three-phase motors are typically more efficient than their single-phase counterparts and more readily available. Adding variable speed control of three-phase motors offers a host of advantages: improved process control and quality, minimized energy consumption and reduced maintenance.
The Single Phase Converter’s active power regulator ensures minimal stress on the power grid, boasting less than 10% current distortion and 0.99 power factor at rated load. Combining a low harmonic solution with a soft starting variable frequency drive typically allows the opportunity to downsize transformers and decrease installation costs. The SPC utilizes the same components found in a variable frequency drive, which significantly reduces maintenance time and expenses.
