Article Abstract – This article will explore the different types of industrial Ever-power electric motor bases and the vast variations they possess in maintainability and supreme drive efficiency. A detailed analysis of a Electric motor base motor foundation technology compared to industry standard (threaded bolt adjustment) bases will emphasize 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 excess pressure. How that belt drive can be installed and taken care of is normally a function of the ease of utilization of the motor base.

Commercial Ever-power Electric motor bases typically fall into two classes. The initial category is known as a fixed-position base. These bases routinely 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 ahead during adjustment the drive pressure decreases as the sheaves (pulleys) move closer to one another. Conversely, as the motor techniques backward the sheaves move further away from one another and tension on the belt raises. 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 because the belt isn’t periodically re-tensioned.”

The second type of motor base can be an automatic or Electric motor base. A popular style 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 and once inertia is overcome it rebounds into position. Automatic tension-managed bases with a springtime design act as a constant resistant power that ensures the motor’s v-belt drive is continually under adequate tension.

System Efficiency vs Proper Belt Tension

Under-tensioned belts lead to slip between your driver sheave and the powered. The outcome of this is:
1. Decreased airflow, which can either enhance 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, over tensioned belts bring about:
1. Decreased bearing life
2. Excessive heat generation
3. Increased engine energy consumption

Think about this a Goldilocks and the Three Bears analogy. The ideal belt tension may be the point in which you have minimal slide and proper power transmission, producing correct airflow with the minimal energy required to do so. The result is the belts operate at an ideal nominal temperature. Any other thing more or much less would either end up being 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 task. It requires proper set up and periodic maintenance guidelines to make sure that the belt drive keeps an adequate level of efficiency. Manufacturers’ suggestions for installing belts and re-tensioning are to “Verify tension frequently through the first a day of operation. Check after jog begin or 1-3 mins of operation, at 8 hours, a day, 100 hours and periodically thereafter are recommended”.
Motor Bases are fabricated of metal which offers a bottom of rugged design, small and smooth in appearance. Bases are style to provide adequate travel, are fully adjustable by the use of a single adjusting screw and also have elongated mounting holes in the bottom plate.
Type A adjustable NEMA Motor Bases style for lighter duty applications
Type B DURABLE bases can take a foot mounted gear reducer

Adjustable Electric motor Bases are heavy gauge steel installation bases designed to simplify the installation of motors and make the tensioning, maintenance and replacement of belts a straightforward efficient task. Fabricated from sheet or metal plate, then primed and finished in a gray rust and corrosion resistant oven-baked complete. Gussets and reinforcing stations on larger models and constant seam welding on all models give these bases power and durability for a long life. An individual (215T frame and smaller) or double (NEMA 254T frame and bigger) zinc plated adjusting screw is provided. Motor installation bolts are included. Adjustable engine bases are created to attach to your existing motor’s base.
Use these bases to pressure motor belts where the engine is definitely above or below the drive device. They allow easy access to adjustment screws on top of the plate. Belt stress can be altered without loosening the electric motor hold-down bolts. Alignment is usually managed when changing belts. These bases are suitable for blower, compressor, fan, mixer, and pump applications where belt adjustment is necessary. Note: Not for ceiling or aspect wall installations.
Check away ever-power wide selection of motor mounting bases which will help position motors and change belt tension during set up and maintenance of shaded-pole and PSC motors found in fans, blowers, direct-drive heating and AC applications and more. Find adjustable metal bases, pivot bases, automated motor bases, resilient ring installation bases and more in an array of configurations.
