Article Abstract – This article will explore the various types of commercial Ever-power motor bases and the vast differences they possess in maintainability and greatest drive efficiency. An in depth analysis of a Electric motor base motor base technology compared to industry standard (threaded bolt adjustment) bases will emphasize the energy savings, performance improvement and payback of retrofitting with a Engine 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 excess stress. How that belt drive is usually installed and preserved is normally a function of the simple usage of the motor base.
Commercial Ever-power Motor bases typically fall into two groups. The initial category is actually a fixed-position bottom. These bases typically have one or two adjusting points in which a nut is switched clockwise or counter clockwise to move the motor forwards or backward. As the electric motor moves forwards during adjustment the drive stress decreases as the sheaves (pulleys) move nearer to one another. Conversely, as the engine techniques backward the sheaves move further away from each other and tension on the belt improves. The U.S. Department of Energy publishes that notched v-belt drive efficiency “deteriorates by as much as 5% (to a nominal efficiency of 93%) over time if slippage occurs since the belt isn’t periodically re-tensioned.”
The second type of motor base can be an automatic or Motor base. A popular design is a spring-loaded edition that instantly adjusts for changes in center distance. Whenever a engine operates, the starting torque causes the drive to flex somewhat forward as soon as inertia is conquer it rebounds into placement. Automatic tension-controlled bases with a spring design become a constant resistant power that ensures the motor’s v-belt drive is continually under adequate tension.
System Performance vs Proper Belt Tension
Under-tensioned belts lead to slip between the driver sheave and the driven. The results of this is:
1. Decreased airflow, which can either boost runtime or reduce occupancy comfort.
2. Decreased power transmission performance and increased belt temperature because of the friction due to the slippage.
3. Decreased overall element 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 perfect belt tension may be the point in which you have minimal slide and proper power tranny, producing correct airflow with the minimum energy necessary to do so. The effect is the belts operate at the perfect nominal temperature. Anything more or much less would either become as well hot or too cool for Goldie.
Achieving and regularly maintaining this level of tension when utilizing a fixed-position base could be a difficult job. It requires proper installation and periodic maintenance best practices to make sure that the belt drive keeps an adequate degree of efficiency. Manufacturers’ recommendations for setting up belts and re-tensioning are to “Examine tension frequently during the first 24 hours of procedure. Check after jog start or 1-3 a few minutes of operation, at 8 hours, a day, 100 hours and periodically thereafter are recommended”.
Engine Bases are fabricated of metal which offers a bottom of rugged design, small and smooth to look at. Bases are design to provide adequate travel, are completely adjustable by the usage of a single adjusting screw and also have elongated mounting holes in the bottom plate.

Adjustable Electric motor Bases are heavy gauge steel installation bases made to simplify installing 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 complete. Gussets and reinforcing channels on larger products and constant seam welding on all units give these bases strength and durability for a long life. An individual (215T frame and smaller sized) or double (NEMA 254T frame and bigger) zinc plated adjusting screw is usually provided. Motor installation bolts are included. Adjustable electric motor bases are made to install to your existing motor’s base.
Make use of these bases to pressure motor belts where the motor is usually above or below the drive unit. They allow easy access to adjustment screws on top of the plate. Belt stress can be adjusted without loosening the engine hold-down bolts. Alignment is certainly preserved when changing belts. These bases are suitable for blower, compressor, fan, mixer, and pump applications where belt adjustment is required. Note: Not for ceiling or part wall installations.
Check away ever-power wide range of motor mounting bases that can help position motors and modify belt tension during installation 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, automatic motor bases, resilient ring installation bases and more in an array of configurations.
