Article Abstract – This content will explore the different types of industrial Ever-power motor bases and the vast distinctions they possess in maintainability and best drive efficiency. A detailed analysis of a Engine base motor bottom technology compared to industry regular (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 significant piece of the system’s overall efficiency. That efficiency could be adversely affected by belt slippage or excess stress. How that belt drive is installed and maintained is typically a function of the ease of utilization of the motor base.
Commercial Ever-power Motor bases typically fall into two types. The first category is actually a fixed-position foundation. These bases typically have one or two adjusting points in which a nut is turned clockwise or counter clockwise to move the motor ahead or backward. As the engine moves forward during adjustment the drive pressure reduces as the sheaves (pulleys) move nearer to each other. Conversely, as the engine movements backward the sheaves move further away from one another and pressure on the belt improves. The U.S. Department of Energy publishes that notched v-belt drive performance “deteriorates by as much as 5% (to a nominal efficiency of 93%) over time if slippage occurs because the belt is not periodically re-tensioned.”
The second kind of motor base is an automatic or Electric motor base. A popular design is a spring-loaded edition that immediately adjusts for adjustments in center distance. Whenever a motor operates, the beginning torque causes the drive to flex somewhat forward as soon as inertia is get over it rebounds into position. Automatic tension-controlled bases with a springtime design become a constant resistant push that guarantees the motor’s v-belt drive is continually under adequate tension.
System Efficiency vs Proper Belt Tension
Under-tensioned belts lead to slip between your driver sheave and the driven. The outcome of this is:
1. Decreased airflow, which can either boost runtime or reduce occupancy comfort.
2. Decreased power transmission effectiveness and improved belt temperature because of the friction caused by the slippage.
3. Decreased overall component life.
Alternatively, more than tensioned belts result in:
1. Decreased bearing life
2. Excessive heat generation
3. Increased engine energy consumption
Consider this a Goldilocks and the 3 Bears analogy. The ideal belt tension may be the point where you have minimal slide and proper power tranny, producing correct airflow with the minimal energy required to do so. The effect may be the belts operate at an ideal nominal temperature. Any other thing more or less would either be as well hot or too frosty for Goldie.
Achieving and consistently maintaining this degree of tension when using a fixed-position base could be a difficult task. It requires proper set up and periodic maintenance guidelines to make sure that the belt drive maintains an adequate level of efficiency. Manufacturers’ suggestions for setting up belts and re-tensioning are to “Check tension frequently through the first 24 hours of operation. Check after jog start or 1-3 moments of operation, at 8 hours, a day, 100 hours and periodically thereafter are recommended”.
Engine Bases are fabricated of steel which offers a base of rugged design, compact and smooth to look at. 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 Motor Bases are 
heavy gauge steel mounting bases designed to simplify installing motors and make the tensioning, maintenance and replacement of belts a straightforward effective 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 units and constant seam welding on all devices give these bases power and durability for an extended life. A single (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 motor bases are designed to attach to your existing motor’s base.
Make use of these bases to tension motor belts where in fact the engine is above or below the drive device. They allow quick access to adjustment screws on top of the plate. Belt stress can be adjusted without loosening the electric motor hold-down bolts. Alignment is certainly managed when changing belts. These bases are ideal for blower, compressor, fan, mixer, and pump applications where belt adjustment is required. Note: Not for ceiling or side wall installations.
Check away ever-power wide selection of motor installation bases that will help position motors and modify belt tension during set up and maintenance of shaded-pole and PSC motors used in enthusiasts, blowers, direct-drive heating and AC applications and more.
