Article Abstract – This content will explore the various types of commercial Ever-power engine bases and the vast variations they have in maintainability and greatest drive efficiency. An in depth analysis of a Electric motor base motor base technology compared to industry regular (threaded bolt adjustment) bases will emphasize 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 extra pressure. How that belt drive is usually installed and managed is normally a function of the ease of use of the motor base.
Commercial Ever-power Engine bases typically fall into two groups. The first category is known as a fixed-position bottom. These bases routinely have one or two adjusting points in which a nut is switched clockwise or counter clockwise to move the motor forwards or backward. As the engine moves forwards during adjustment the drive tension reduces as the sheaves (pulleys) move closer to each other. Conversely, as the motor techniques backward the sheaves move further away from one another and pressure on the belt boosts. The U.S. Section 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 periodically re-tensioned.”
The second kind of motor base can be an automatic or Electric motor base. A popular design is a spring-loaded version that immediately adjusts for adjustments in center distance. When a engine operates, the beginning torque causes the drive to flex slightly forward as soon as inertia is conquer it rebounds into position. Automatic tension-controlled bases with a spring design act as a constant resistant force 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 the driver sheave and the powered. The outcome of this is:
1. Decreased airflow, which can either increase runtime or decrease 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, more than tensioned belts bring about:
1. Decreased bearing life
2. Excessive heat generation
3. Increased engine energy consumption
Think about this a Goldilocks and the 3 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 result may be the belts operate at the perfect nominal temperature. Anything more or much less would either become too hot or too chilly for Goldie.
Achieving and regularly maintaining this degree of tension when using a fixed-position base could be a difficult job. It requires proper installation and periodic maintenance guidelines to ensure that the belt drive keeps an adequate degree of efficiency. Manufacturers’ suggestions for setting up belts and re-tensioning are to “Check tension frequently through the first 24 hours of procedure. Check after jog start or 1-3 a few minutes of operation, at 8 hours, a day, 100 hours and periodically thereafter are recommended”.
Motor Bases are fabricated of steel which offers a base of rugged design, small and smooth to look at. Bases are style to provide sufficient travel, are completely adjustable by the utilization 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 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 stations on larger systems and continuous 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 definitely provided. Motor installation bolts are included. Adjustable motor bases are created to mount to your existing motor’s base.
Make use of these bases to stress motor belts where the electric motor is above or below the drive device. They allow easy access to adjustment screws on top of the plate. Belt stress can be adjusted without loosening the engine hold-down bolts. Alignment is definitely managed when changing belts. These bases are ideal for blower, compressor, enthusiast, mixer, and pump applications where belt adjustment is required. Note: Not really for ceiling or part wall installations.
Check away ever-power wide range of motor installation bases that will help position motors and adjust belt tension during set up and maintenance of shaded-pole and PSC motors found in supporters, blowers, direct-drive heating system and AC applications and more. Find adjustable steel bases, pivot bases, automatic motor bases, resilient ring mounting bases and more in an array of configurations.
