Lovejoy Variable Speed Drives

Variable speed drives are essential because many applications don't operate at a consistent speed all the time, primarily due to varying external conditions. Changes in load, application demands, or other factors necessitate adjustments to the revolutions per minute (RPM) of the driven shaft.

Variable speed belt drives offer the flexibility required to optimize application efficiency and productivity, all while remaining a cost-effective solution. In the most common setup, a belt links a variable-speed pulley to a driven sheave. The pulley is affixed to a motor shaft that maintains a constant speed. Consequently, the speed at the driven shaft is determined by the ratio of the pitch diameters of the pulley and the sheave.

• A very economical and reliable method of speed change

• Allows the user to find the ideal speed without changing sheaves and belts; especially important on applications where final driven speed is critical and difficult to attain with two fixed-diameter sheave

• The speed range within the ratio is infinite, and speed change is accomplished quickly, while the drive is running

• Can be used as a highly efficient belt tensioner, with no adjustment necessary

• Offers a form of “soft start,” eliminating belt slip and premature wear

• On-belt drives with inherent high torque start-up requirements
