Article Abstract – This content will explore the different types of industrial Ever-power engine bases and the vast distinctions they possess in maintainability and ultimate drive efficiency. An in depth analysis of a Motor base motor bottom technology compared to industry standard (threaded bolt adjustment) bases will highlight the energy savings, efficiency improvement and payback of retrofitting with a 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 affected by belt slippage or excess tension. How that belt drive can be installed and maintained is typically a function of the ease of use of the motor base.

Commercial Ever-power Electric motor bases typically fall into two types. The initial category is actually a fixed-position bottom. These bases typically have a couple of adjusting points in which a nut is turned clockwise or counter clockwise to go the motor ahead or backward. As the electric motor moves forwards during adjustment the drive stress reduces as the sheaves (pulleys) move closer to one another. Conversely, as the engine moves backward the sheaves move additional away from one another and tension 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 since the belt isn’t periodically re-tensioned.”

The second type of motor base is an automatic or Electric motor base. A popular design is a spring-loaded version that immediately adjusts for changes in center distance. Whenever a engine operates, the beginning 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 springtime design act as a constant resistant drive that ensures the motor’s v-belt drive is constantly under adequate tension.

System Efficiency vs Proper Belt Tension

Under-tensioned belts result in slip between your driver sheave and the driven. 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 engine energy consumption

Consider this a Goldilocks and the 3 Bears analogy. The perfect belt tension may be the point in which you have minimal slide and proper power transmitting, producing proper 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 chilly for Goldie.
Achieving and consistently maintaining this level of tension when utilizing a fixed-position base can be a difficult task. It requires proper set up and periodic maintenance best practices to ensure that the belt drive maintains an adequate level of efficiency. Manufacturers’ suggestions for setting up belts and re-tensioning are to “Check tension frequently during the first a day of operation. Check after jog begin or 1-3 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 design to provide adequate travel, are completely adjustable by the usage of an individual adjusting screw and also have elongated installation holes in the bottom plate.

Adjustable Engine Bases are large gauge steel installation bases designed to simplify the installation of motors and make the tensioning, maintenance and replacement of belts a simple effective task. Fabricated from sheet or steel plate, then primed and completed in a gray rust and corrosion resistant oven-baked finish. Gussets and reinforcing channels on larger systems and continuous seam welding on all devices give these bases power and durability for an extended life. An individual (215T frame and smaller) or double (NEMA 254T frame and larger) zinc plated adjusting screw is usually provided. Motor installation bolts are included. Adjustable motor bases are designed to attach to your existing motor’s base.
Make use of these bases to pressure motor belts where the electric motor is usually above or below the drive unit. They allow quick access to adjustment screws on top of the plate. Belt pressure can be altered without loosening the engine hold-down bolts. Alignment is definitely preserved when changing belts. These bases are ideal for blower, compressor, lover, mixer, and pump applications where belt adjustment is necessary. Note: Not for ceiling or side wall installations.
Check away ever-power wide selection of motor mounting bases that will help position motors and modify belt tension during installation and maintenance of shaded-pole and PSC motors used in supporters, blowers, direct-drive heating and AC applications and more.
