Article Abstract – This article will explore the various types of commercial Ever-power motor bases and the vast distinctions they possess in maintainability and supreme drive efficiency. An in depth analysis of a Motor base motor bottom technology compared to industry regular (threaded bolt adjustment) bases will highlight the energy savings, efficiency improvement and payback of retrofitting with a Engine base.
In Ever-power belt driven applications, belt tension represents a substantial little bit of the system’s overall efficiency. That efficiency can be adversely suffering from belt slippage or excess pressure. How that belt drive is definitely installed and maintained is normally a function of the simple use of the motor base.
Commercial Ever-power Electric motor bases typically fall into two types. The first category is known as a fixed-position bottom. These bases typically have a couple of adjusting points in which a nut is turned clockwise or counter clockwise to move the motor ahead or backward. As the electric motor moves ahead during adjustment the drive stress reduces as the sheaves (pulleys) move nearer to each other. Conversely, as the electric motor moves backward the sheaves move additional away from each other and tension on the belt boosts. The U.S. Department 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 because the belt isn’t periodically re-tensioned.”
The second kind of motor base is an automatic or Engine base. A popular design is a spring-loaded version that immediately adjusts for adjustments in center distance. When a engine operates, the starting torque causes the drive to flex slightly forward as soon as inertia is get over it rebounds into placement. Automatic tension-controlled bases with a spring design act as a constant resistant pressure that ensures 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 powered. The results of this is:
1. Decreased airflow, which can either increase runtime or reduce occupancy comfort.
2. Decreased power transmission efficiency and improved belt temperature because of the friction due to the slippage.
3. Decreased overall component life.
Alternatively, over tensioned belts result in:
1. Decreased bearing life
2. Excessive heat generation
3. Increased engine energy consumption
Consider this a Goldilocks and the Three Bears analogy. The ideal belt tension is the point in which you have minimal slip and proper power transmitting, producing correct airflow with the minimum energy necessary to do so. The effect is the belts operate at an ideal nominal temperature. Anything more or much less would either be as well hot or too cold for Goldie.
Achieving and consistently maintaining this level of tension when utilizing a fixed-position base can be a difficult job. It requires proper installation and periodic maintenance guidelines to make sure that the belt drive keeps an adequate degree of efficiency. Manufacturers’ recommendations for installing belts and re-tensioning are to “Examine tension frequently through the first a day of operation. Check after jog start or 1-3 mins 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, compact and smooth to look at. Bases are design to provide adequate travel, are fully adjustable by the usage of a single 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 metal plate, then primed and completed in a gray rust and corrosion resistant oven-baked complete. Gussets and reinforcing stations on larger systems and constant seam welding on all devices give these bases power and durability for a long life. An individual (215T frame and smaller sized) or double (NEMA 254T frame and larger) zinc plated adjusting screw is usually provided. Motor installation bolts are included. Adjustable motor bases are made to install to your existing motor’s base.
Use these bases to pressure motor belts where the engine is certainly above or below the drive device. They allow quick access to adjustment 
screws along with the plate. Belt stress can be altered without loosening the motor hold-down bolts. Alignment can be maintained when changing belts. These bases are suitable for blower, compressor, fan, mixer, and pump applications where belt adjustment is required. Note: Not really for ceiling or aspect wall installations.
Check out ever-power wide selection of motor mounting bases that will help placement motors and adjust belt tension during installation and maintenance of shaded-pole and PSC motors found in fans, blowers, direct-drive heating system and AC applications and more. Find adjustable steel bases, pivot bases, automatic motor bases, resilient band installation bases and more in a wide selection of configurations.
