Article Abstract – This content will explore the different types of industrial Ever-power electric motor bases and the vast variations they possess in maintainability and ultimate drive efficiency. A detailed analysis of a Engine base motor foundation technology compared to industry standard (threaded bolt adjustment) bases will highlight the energy savings, efficiency improvement and payback of retrofitting with a Electric motor 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 typically a function of the ease of use of the motor base.

Commercial Ever-power Motor bases typically fall into two groups. The initial category is known as a fixed-position base. These bases routinely have one or two adjusting points where a nut is turned clockwise or counter clockwise to go the motor forward or backward. As the electric motor moves forwards during adjustment the drive pressure decreases as the sheaves (pulleys) move nearer to each other. Conversely, as the motor techniques backward the sheaves move additional away from each other and pressure on the belt increases. The U.S. Department of Energy publishes that notched v-belt drive performance “deteriorates by as much as 5% (to a nominal efficiency of 93%) as time passes if slippage occurs because the belt isn’t periodically re-tensioned.”

The second type of motor base can be an automatic or Motor base. A popular design is a spring-loaded edition that instantly adjusts for changes in center distance. When a engine operates, the beginning torque causes the drive to flex somewhat forward as soon as inertia is get over it rebounds into placement. Automatic tension-managed bases with a spring design act as a constant resistant push that guarantees the motor’s v-belt drive is continually under adequate tension.

System Efficiency 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, that may either enhance runtime or reduce occupancy comfort.
2. Decreased power transmission effectiveness and increased belt temperature because of the friction due to the slippage.
3. Decreased overall element life.

Alternatively, more than tensioned belts bring about:
1. Decreased bearing life
2. Excessive heat generation
3. Increased engine energy consumption

Consider 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 tranny, producing correct airflow with the minimal energy required to do so. The effect 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 regularly maintaining this level of tension when utilizing a fixed-position base could be a difficult task. It requires proper installation and periodic maintenance guidelines to ensure that the belt drive maintains an adequate degree of efficiency. Manufacturers’ recommendations for setting up belts and re-tensioning are to “Examine tension frequently during the first a day of procedure. Check after jog begin or 1-3 mins of operation, at 8 hours, a day, 100 hours and periodically thereafter are recommended”.

Adjustable Engine Bases are weighty gauge steel mounting bases designed to simplify installing motors and make the tensioning, maintenance and replacement of belts a straightforward efficient task. Fabricated from sheet or steel plate, then primed and finished in a gray rust and corrosion resistant oven-baked finish. Gussets and reinforcing channels on larger systems and constant seam welding on all units 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 mounting bolts are included. Adjustable engine bases are created to install to your existing motor’s base.
Use these bases to tension motor belts where the engine is above or below the drive unit. They allow easy access to adjustment screws on top of the plate. Belt tension can be modified without loosening the electric motor hold-down bolts. Alignment is certainly 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 side wall installations.
Check away ever-power wide selection of motor installation bases that can help position motors and adjust belt tension during set up and maintenance of shaded-pole and PSC motors used in enthusiasts, blowers, direct-drive heating and AC applications and more. Find adjustable metal bases, pivot bases, automated motor bases, resilient band installation bases and more in a wide range of configurations.
