Article Abstract – This content will explore the different types of commercial Ever-power electric motor bases and the vast differences they possess in maintainability and greatest drive efficiency. An in depth analysis of a Motor 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 substantial piece of the system’s overall efficiency. That efficiency can be adversely affected by belt slippage or excess pressure. How that belt drive is certainly installed and maintained is typically a function of the ease of usage of the motor base.
Commercial Ever-power Engine bases typically fall into two categories. The first category is actually a fixed-position base. These bases typically have a couple of adjusting points where a nut is switched clockwise or counter clockwise to go the motor forwards or backward. As the electric motor moves forwards during adjustment the drive pressure reduces as the sheaves (pulleys) move nearer to each other. Conversely, as the electric motor movements backward the sheaves move further away from one another and stress on the belt boosts. 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 isn’t periodically re-tensioned.”
The second kind of motor base is an automatic or Electric motor base. A popular style is a spring-loaded version that automatically adjusts for adjustments in center distance. Whenever a engine operates, the beginning torque causes the drive to flex slightly forward and once inertia is conquer it rebounds into position. Automatic tension-managed bases with a spring design become a constant resistant drive 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 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 due to the slippage.
3. Decreased overall component life.
Alternatively, over tensioned belts bring about:
1. Decreased bearing life
2. Excessive heat generation
3. Increased motor energy consumption
Think about this a Goldilocks and the Three Bears analogy. The perfect belt tension is the point in which you have minimal slide and proper power transmitting, producing appropriate airflow with the minimum energy required to do so. The result is the belts operate at the perfect nominal temperature. Any other thing more or much less would either end up being as well hot or too cold for Goldie.
Achieving and regularly maintaining this level of tension when using a fixed-position base can be a difficult task. It requires proper set up and periodic maintenance best practices to make sure that the belt drive maintains an adequate level of efficiency. Manufacturers’ recommendations for installing belts and re-tensioning are to “Check tension frequently during the first 24 hours of procedure. Check after jog start or 1-3 minutes of operation, at 8 hours, a day, 100 hours and periodically thereafter are recommended”.
Electric motor Bases are fabricated of steel which offers a foundation of rugged design, small and smooth in appearance. Bases are style to provide adequate travel, are completely adjustable by the use of a single adjusting screw and have elongated mounting holes in the base plate.

Adjustable Electric motor Bases are heavy gauge steel installation bases designed 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 finished in a gray rust and corrosion resistant oven-baked complete. Gussets and reinforcing stations on larger devices and continuous seam welding on all systems give these bases power and durability for an extended life. An individual (215T frame and smaller) or double (NEMA 254T frame and larger) zinc plated adjusting screw is provided. Motor installation bolts are included. Adjustable electric motor bases are created to install to your existing motor’s base.
Make use of these bases to tension motor belts where the engine is above or below the drive unit. They allow easy access to adjustment screws along with the plate. Belt stress can be altered without loosening the electric motor hold-down bolts. Alignment is managed when changing belts. These bases are suitable for blower, compressor, enthusiast, mixer, and pump applications where belt adjustment is necessary. Note: Not really for ceiling or side wall installations.
Check away ever-power wide range of motor installation bases which will help placement motors and adapt belt tension during installation and maintenance of shaded-pole and PSC motors used in supporters, blowers, direct-drive heating and AC applications and more.
