Article Abstract – This article will explore the various types of commercial Ever-power electric motor bases and the vast differences they have in maintainability and supreme drive efficiency. A detailed analysis of a Electric motor base motor base technology compared to industry standard (threaded bolt adjustment) bases will highlight the energy savings, performance improvement and payback of retrofitting with a Engine base.
In Ever-power belt driven applications, belt tension represents a significant little bit of the system’s overall efficiency. That efficiency can be adversely suffering from belt slippage or extra stress. How that belt drive is installed and maintained is typically a function of the simple usage of the motor base.
Commercial Ever-power Motor bases typically fall into two categories. The first category is actually a fixed-position bottom. These bases typically have a couple of adjusting points where a nut is switched clockwise or counter clockwise to go the motor ahead or backward. As the engine moves ahead during adjustment the drive pressure reduces as the sheaves (pulleys) move closer to each other. Conversely, as the engine movements backward the sheaves move further away from each other and pressure on the belt boosts. 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%) as time passes if slippage occurs because the belt is not Motor base china periodically re-tensioned.”
The second kind of motor base is an automatic or Engine base. A popular style is a spring-loaded version that instantly 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-controlled bases with a springtime design act as a constant resistant push that ensures the motor’s v-belt drive is constantly 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 increase runtime or decrease occupancy comfort.
2. Decreased power transmission efficiency 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 electric motor energy consumption
Consider this a Goldilocks and the 3 Bears analogy. The ideal belt tension may be the point in which you have minimal slide and proper power transmission, producing proper airflow with the minimum energy required to do so. The effect may be the belts operate at an ideal nominal temperature. Any other thing more or much less would either become as well hot or too cool for Goldie.
Achieving and consistently maintaining this degree of tension when using a fixed-position base could be a difficult job. It requires proper set up and periodic maintenance guidelines to ensure that the belt drive keeps an adequate level of efficiency. Manufacturers’ recommendations for setting up belts and re-tensioning are to “Verify tension frequently during the first a day 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 design to provide sufficient travel, are fully adjustable by the use of a single adjusting screw and also have elongated mounting holes in the bottom plate.

Adjustable Electric motor Bases are heavy gauge steel mounting bases made to simplify the installation of motors and make the tensioning, maintenance and replacement of belts a simple effective task. Fabricated from sheet or metal plate, after that primed and finished in a gray rust and corrosion resistant oven-baked finish. Gussets and reinforcing channels on larger devices and constant seam welding on all units give these bases power and durability for a long life. An individual (215T frame and smaller) or double (NEMA 254T frame and larger) zinc plated adjusting screw can be provided. Motor installation bolts are included. Adjustable electric motor bases are made to mount to your existing motor’s base.
Use these bases to tension motor belts where the motor is certainly above or below the drive unit. They allow quick access to adjustment screws on top of the plate. Belt stress can be adjusted without loosening the motor hold-down bolts. Alignment is usually maintained when changing belts. These bases are ideal for blower, compressor, fan, 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 mounting bases that can help position motors and modify belt tension during installation and maintenance of shaded-pole and PSC motors used in fans, 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 selection of configurations.
