Article Abstract – This article will explore the various types of commercial Ever-power engine bases and the vast differences they have in maintainability and supreme drive efficiency. An in depth analysis of a Engine base motor foundation technology compared to industry regular (threaded bolt adjustment) bases will highlight the energy savings, efficiency improvement and payback of retrofitting with a Motor base.

In Ever-power belt driven applications, belt tension represents a significant piece of the system’s overall efficiency. That efficiency can be adversely affected by belt slippage or extra tension. How that belt drive is installed and managed is normally a function of the ease of usage of the motor base.

Commercial Ever-power Motor bases typically fall into two classes. The first category is known as a fixed-position base. These bases typically have a couple of adjusting points in which a nut is switched clockwise or counter clockwise to go the motor forwards or backward. As the electric motor moves ahead during adjustment the drive stress decreases as the sheaves (pulleys) move nearer to each other. Conversely, as the electric motor movements backward the sheaves move additional away from one another and tension on the belt boosts. The U.S. Division of Energy publishes that notched v-belt drive efficiency “deteriorates by as much as 5% (to a nominal efficiency of 93%) as time passes if slippage occurs since the belt is not periodically re-tensioned.”

The second kind of motor base can be an automatic or Motor base. A popular design is a spring-loaded edition that immediately adjusts for adjustments in center distance. When a electric motor operates, the starting torque causes the drive to flex slightly forward as soon as inertia is conquer it rebounds into placement. Automatic tension-managed bases with a springtime design act as a constant resistant power that guarantees the motor’s v-belt drive is continually under adequate tension.

System Efficiency vs Proper Belt Tension

Under-tensioned belts result in slip between your driver sheave and the powered. The outcome of this is:
1. Decreased airflow, which can either increase runtime or reduce occupancy comfort.
2. Decreased power transmission performance and increased belt temperature due to the friction caused by the slippage.
3. Decreased overall component life.

Alternatively, more than tensioned belts bring about:
1. Decreased bearing life
2. Excessive heat generation
3. Increased motor energy consumption

Consider this a Goldilocks and the 3 Bears analogy. The ideal belt tension is the point where you have minimal slip and proper power transmission, producing proper airflow with the minimum energy required to do so. The result may be the belts operate at an ideal nominal temperature. Any other thing more or much less would either end up being as well hot or too cold for Goldie.
Achieving and consistently maintaining this level of tension when using a fixed-position base could be a difficult job. It requires proper set up and periodic maintenance best practices to ensure that the belt drive maintains an adequate level of efficiency. Manufacturers’ recommendations for installing belts and re-tensioning are to “Examine tension frequently during the first 24 hours of operation. Check after jog begin or 1-3 a few minutes of operation, at 8 hours, 24 hours, 100 hours and periodically thereafter are recommended”.
Engine Bases are fabricated of metal which offers a base of rugged design, small and smooth in appearance. Bases are style to provide adequate travel, are completely adjustable by the usage of a single adjusting screw and have elongated mounting holes in the base plate.

Adjustable Engine Bases are large gauge steel installation bases made to simplify the installation of motors and make the tensioning, maintenance and replacement of belts a simple efficient task. Fabricated from sheet or metal plate, after that primed and finished in a gray rust and corrosion resistant oven-baked finish. Gussets and reinforcing channels on larger products and constant seam welding on all products give these bases power and durability for a long life. A single (215T frame and smaller) or double (NEMA 254T frame and bigger) zinc plated adjusting screw is definitely provided. Motor installation bolts are included. Adjustable engine bases are made to attach to your existing motor’s base.
Use these bases to pressure motor belts where in fact the engine is above or below the drive unit. They allow quick access to adjustment screws along with the plate. Belt pressure can be altered without loosening the engine hold-down bolts. Alignment is preserved when changing belts. These bases are ideal for blower, compressor, lover, mixer, and pump applications where belt adjustment is necessary. Note: Not really for ceiling or part wall installations.
Check away ever-power wide range of motor installation bases that will help position motors and adjust belt tension during set up and maintenance of shaded-pole and PSC motors used in followers, blowers, direct-drive heating system and AC applications and more. Find adjustable steel bases, pivot bases, automated motor bases, resilient ring mounting bases and more in a wide selection of configurations.
