Article Abstract – This article will explore the different types of commercial Ever-power electric motor bases and the vast variations they have in maintainability and ultimate drive efficiency. An in depth analysis of a Motor base motor base technology in comparison to industry standard (threaded bolt adjustment) bases will emphasize the energy savings, performance improvement and payback of retrofitting with a 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 suffering from belt slippage or extra pressure. How that belt drive can be installed and taken care of is normally a function of the ease of use of the motor base.

Commercial Ever-power Electric motor bases typically fall into two groups. The initial category is actually 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 motor moves forwards during adjustment the drive tension reduces as the sheaves (pulleys) move nearer to each other. Conversely, as the motor techniques backward the sheaves move further away from each other and tension on the belt raises. 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 isn’t periodically re-tensioned.”

The second type of motor base can be an automatic or Engine base. A popular design is a spring-loaded version that instantly adjusts for changes in center distance. Whenever a electric motor operates, the starting torque causes the drive to flex slightly forward and once inertia is conquer it rebounds into placement. Automatic tension-managed bases with a spring design act as a constant resistant force that ensures the motor’s v-belt drive is continually under adequate tension.

System Performance vs Proper Belt Tension

Under-tensioned belts lead to slip between the driver sheave and the driven. The outcome of this is:
1. Decreased airflow, which can either increase runtime or decrease occupancy comfort.
2. Decreased power transmission performance and increased belt temperature due to the friction due to the slippage.
3. Decreased overall element life.

Alternatively, over tensioned belts result in:
1. Decreased bearing life
2. Excessive heat generation
3. Increased motor energy consumption

Think about this a Goldilocks and the Three Bears analogy. The perfect belt tension may be the point where you have minimal slip and proper power transmitting, producing appropriate airflow with the minimum energy required to do so. The result is the belts operate at the perfect nominal temperature. Anything more or much less would either end up being too hot or too cool for Goldie.
Achieving and regularly maintaining this level of tension when utilizing a fixed-position base can be a difficult job. It requires proper installation and periodic maintenance best practices to ensure that the belt drive maintains an adequate degree of efficiency. Manufacturers’ recommendations for installing belts and re-tensioning are to “Verify tension frequently during the first a day of procedure. Check after jog begin or 1-3 a few minutes of operation, at 8 hours, 24 hours, 100 hours and periodically thereafter are recommended”.
Motor Bases are fabricated of metal which offers a foundation of rugged design, small 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 mounting holes in the bottom plate.

Adjustable Electric motor Bases are large gauge steel installation bases made to simplify the installation of motors and make the tensioning, maintenance and replacement of belts a simple efficient task. Fabricated from sheet or steel plate, then primed and finished in a gray rust and corrosion resistant oven-baked complete. Gussets and reinforcing stations on larger products and constant seam welding on all units give these bases strength and durability for a long life. An individual (215T frame and smaller sized) or double (NEMA 254T frame and bigger) zinc plated adjusting screw is provided. Motor installation bolts are included. Adjustable engine bases are created to mount to your existing motor’s base.
Make use of these bases to stress motor belts where in fact the motor can be above or below the drive unit. They allow easy access to adjustment screws along with the plate. Belt pressure can be altered without loosening the engine hold-down bolts. Alignment is definitely maintained when changing belts. These bases are ideal for blower, compressor, enthusiast, mixer, and pump applications where belt adjustment is necessary. Note: Not really for ceiling or aspect wall installations.
Check out ever-power wide range of motor mounting bases that can help position motors and adjust belt tension during set up and maintenance of shaded-pole and PSC motors found in followers, blowers, direct-drive heating and AC applications and more. Find adjustable steel bases, pivot bases, automated motor bases, resilient band mounting bases and more in an array of configurations.
