Article Abstract – This content will explore the various types of commercial Ever-power engine bases and the vast differences they have in maintainability and ultimate drive efficiency. A detailed analysis of a Engine base motor foundation technology in comparison to industry standard (threaded bolt adjustment) bases will highlight the energy savings, overall performance improvement and payback of retrofitting with a Engine base.
In Ever-power belt driven applications, belt tension represents a substantial piece of the system’s overall efficiency. That efficiency could be adversely suffering from belt slippage or excess tension. How that belt drive is installed and taken care of is normally a function of the simple usage of the motor base.
Commercial Ever-power Electric motor bases typically fall into two classes. The 1st category is actually a fixed-position base. These bases typically have one or two 
adjusting points in which a nut is switched clockwise or counter clockwise to go the motor forwards or backward. As the motor moves ahead during adjustment the drive tension decreases as the sheaves (pulleys) move nearer to one another. Conversely, as the motor techniques backward the sheaves move additional away from each other and tension on the belt boosts. The U.S. Section of Energy publishes that notched v-belt drive effectiveness “deteriorates by as much as 5% (to a nominal efficiency of 93%) over time if slippage occurs since the belt is not periodically re-tensioned.”
The second type of motor base can be an automatic or Engine base. A popular style is a spring-loaded edition that instantly adjusts for changes in center distance. Whenever a electric motor operates, the beginning torque causes the drive to flex slightly forward and once inertia is conquer it rebounds into placement. Automatic tension-controlled bases with a spring design act as a constant resistant pressure that guarantees the motor’s v-belt drive is continually under adequate tension.
System Effectiveness vs Proper Belt Tension
Under-tensioned belts result in slip between the driver sheave and the powered. The results of this is:
1. Decreased airflow, which can either increase runtime or decrease occupancy comfort.
2. Decreased power transmission efficiency and increased belt temperature because of the friction caused by the slippage.
3. Decreased overall element life.
Alternatively, over tensioned belts result in:
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 transmitting, producing proper airflow with the minimum energy required to do so. The result is the belts operate at an ideal nominal temperature. Any other thing more or less would either end up being too hot or too chilly for Goldie.
Achieving and regularly maintaining this level of tension when using a fixed-position base can be a difficult job. It requires proper installation and periodic maintenance guidelines to make sure that the belt drive maintains an adequate level of efficiency. Manufacturers’ suggestions for installing belts and re-tensioning are to “Examine tension frequently during the first a day of procedure. Check after jog start or 1-3 a few minutes of operation, at 8 hours, 24 hours, 100 hours and periodically thereafter are recommended”.
Motor Bases are fabricated of steel which offers a base of rugged design, small and smooth in appearance. Bases are design to provide sufficient travel, are fully adjustable by the use of an individual adjusting screw and have elongated mounting holes in the base plate.

Adjustable Engine Bases are heavy gauge steel installation bases made to simplify installing motors and make the tensioning, maintenance and replacement of belts a straightforward efficient task. Fabricated from sheet or steel plate, after that primed and completed in a gray rust and corrosion resistant oven-baked finish. Gussets and reinforcing channels on larger devices and constant seam welding on all models give these bases strength and durability for a long life. An individual (215T frame and smaller) or double (NEMA 254T frame and larger) zinc plated adjusting screw is definitely provided. Motor mounting bolts are included. Adjustable engine bases are made to install to your existing motor’s base.
Use these bases to tension motor belts where in fact the engine is usually above or below the drive device. They allow quick access to adjustment screws on top of the plate. Belt stress can be altered without loosening the engine hold-down bolts. Alignment is definitely managed when changing belts. These bases are suitable for blower, compressor, lover, mixer, and pump applications where belt adjustment is necessary. Note: Not for ceiling or part wall installations.
Check out ever-power wide selection of motor mounting bases that can help placement motors and modify belt tension during set up and maintenance of shaded-pole and PSC motors used in supporters, 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 range of configurations.
