Article Abstract – This article will explore the various types of commercial Ever-power engine bases and the vast variations they have in maintainability and ultimate drive efficiency. A detailed analysis of a Motor base motor base technology in comparison to industry regular (threaded bolt adjustment) bases will highlight the energy savings, performance improvement and payback of retrofitting with a Electric motor base.

In Ever-power belt driven applications, belt tension represents a substantial piece of the system’s overall efficiency. That efficiency could be adversely suffering from belt slippage or excess stress. How that belt drive is installed and preserved is normally a function of the ease of use of the motor base.

Commercial Ever-power Motor bases typically fall into two categories. The 1st category is known as a fixed-position bottom. These bases typically have a couple of adjusting points in which a nut is switched clockwise or counter clockwise to go the motor forward or backward. As the motor moves forwards during adjustment the drive stress reduces as the sheaves (pulleys) move closer to each other. Conversely, as the engine movements backward the sheaves move further away from one another and stress on the belt improves. The U.S. Section of Energy publishes that notched v-belt drive efficiency “deteriorates by as much as 5% (to a nominal efficiency of 93%) over time if slippage occurs because the belt is not periodically re-tensioned.”

The second kind of motor base is an automatic or Motor base. A popular design is a spring-loaded edition that automatically adjusts for changes in center distance. When a engine operates, the starting torque causes the drive to flex slightly forward as soon as inertia is overcome it rebounds into placement. Automatic tension-managed bases with a spring design act as a constant resistant power that ensures the motor’s v-belt drive is constantly under adequate tension.

System Effectiveness vs Proper Belt Tension

Under-tensioned belts lead to slip between the driver sheave and the powered. The outcome of this is:
1. Decreased airflow, which can either boost runtime or decrease occupancy comfort.
2. Decreased power transmission performance and increased belt temperature due to 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 motor energy consumption

Consider this a Goldilocks and the Three Bears analogy. The perfect belt tension may be the point in which you have minimal slide and proper power transmitting, producing correct airflow with the minimal energy necessary to do so. The result may be the belts operate at the perfect nominal temperature. Any other thing more or much less would either become too hot or too frosty for Goldie.
Achieving and regularly maintaining this degree of tension when utilizing a fixed-position base can be a difficult task. It requires proper set up and periodic maintenance guidelines to make sure that the belt drive keeps an adequate degree of efficiency. Manufacturers’ suggestions for installing belts and re-tensioning are to “Examine tension frequently through the first 24 hours of operation. Check after jog start or 1-3 mins of operation, at 8 hours, a day, 100 hours and periodically thereafter are recommended”.
Electric motor Bases are fabricated of metal which offers a base of rugged design, compact and smooth in appearance. Bases are style to provide sufficient travel, are completely adjustable by the use of an individual adjusting screw and also have elongated installation holes in the bottom plate.

Adjustable Electric motor Bases are weighty 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 steel plate, then primed and completed in a gray rust and corrosion resistant oven-baked complete. Gussets and reinforcing channels on larger systems and constant seam welding on all products give these bases strength and durability for a long life. A single (215T frame and smaller) or double (NEMA 254T frame and larger) zinc plated adjusting screw is definitely provided. Motor mounting bolts are included. Adjustable engine bases are created to install to your existing motor’s base.
Use these bases to pressure motor belts where in fact the motor can be above or below the drive unit. They allow quick access to adjustment screws on top of the plate. Belt tension can be altered without loosening the electric 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 for ceiling or aspect wall installations.
Check away ever-power wide range of motor installation bases that can help placement motors and adjust 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 range of configurations.
