Article Abstract – This article will explore the different types of commercial Ever-power engine bases and the vast variations they possess in maintainability and greatest drive efficiency. A detailed analysis of a Engine base motor bottom technology compared to industry standard (threaded bolt adjustment) bases will highlight the energy savings, functionality 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 suffering from belt slippage or excess tension. How that belt drive is installed and maintained is normally a function of the simple usage of the motor base.
Commercial Ever-power Engine bases typically fall into two classes. The 1st 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 forward 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 engine movements backward the sheaves move further away from one another and pressure on the belt increases. The U.S. Division 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 kind of motor base can be an automatic or Engine base. A popular style is a spring-loaded version that immediately adjusts for changes in center distance. When a electric motor operates, the starting torque causes the drive to flex somewhat forward and once inertia is conquer it rebounds into placement. Automatic tension-managed bases with a spring design become a constant resistant pressure that guarantees the motor’s v-belt drive is continually under adequate tension.
System Performance vs Proper Belt Tension
Under-tensioned belts result in slip between your driver sheave and the driven. The results of this is:
1. Decreased airflow, that may either enhance runtime or decrease occupancy comfort.
2. Decreased power transmission efficiency and increased belt temperature due to 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 motor energy consumption
Think about this a Goldilocks and the 3 Bears analogy. The perfect belt tension is the point in which you have minimal slip and proper power transmission, producing correct airflow with the minimum energy necessary to do so. The effect is the belts operate at the perfect nominal temperature. Any other thing more or less would either be as well hot or too chilly for Goldie.
Achieving and consistently maintaining this level of tension when utilizing a fixed-position base could be a difficult task. It requires proper set up and periodic maintenance guidelines to ensure that the belt drive keeps an adequate level of efficiency. Manufacturers’ suggestions 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 moments 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 sufficient travel, are completely adjustable by the use of an individual adjusting screw and have elongated mounting holes in the bottom plate.

Adjustable Electric motor Bases are large gauge steel mounting bases designed to simplify the installation of motors and make the tensioning, maintenance and replacement of belts a straightforward effective task. Fabricated from sheet or metal plate, after that primed and completed in a gray rust and corrosion resistant oven-baked complete. Gussets and reinforcing channels on larger devices and continuous seam welding on all products give these bases strength and durability for an extended life. An individual (215T frame and smaller sized) or double (NEMA 254T frame and bigger) zinc plated adjusting screw is provided. Motor installation bolts are included. Adjustable motor bases are created to install to your existing motor’s base.
Make use of these bases to tension motor belts where in fact the engine is certainly above or below the drive unit. They allow quick access to adjustment screws along with the plate. Belt pressure can be adjusted without loosening the electric motor hold-down bolts. Alignment is usually managed when changing belts. These bases are ideal 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 range of motor installation bases that will help placement motors and adapt belt tension during installation and maintenance of shaded-pole and PSC motors found in followers, blowers, direct-drive heating and AC applications and more.
