Since not all operations run at uniform speeds due to ambient conditions, Variable Speed Drives are required. Lovejoy Inc.'s Econoline Series of variable speed drives feature maintenance-free designs at economical costs. These drives showcase driven speed ratios of 1.6:1 and 2.7:1, and horsepower levels that range from fractional values to 5 HP (at a motor speed rate of 1,750 RPM). They also sport comprehensive cast iron flanges, and various model configurations.
The Econoline Series is ideal for both fixed or adjustable center drives, via classic 4L and 5L section drive belts.
