Article Abstract – This article will explore the various types of commercial Ever-power motor bases and the vast variations they possess in maintainability and ultimate drive efficiency. A detailed analysis of a Motor base motor bottom technology in comparison to industry regular (threaded bolt adjustment) bases will emphasize the energy savings, overall performance 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 can be adversely suffering from belt slippage or excess tension. How that belt drive is installed and taken care of is typically a function of the simple utilization of the motor base.
Commercial Ever-power Electric motor bases typically fall into two classes. The 1st category is actually a fixed-position base. These bases typically have a couple of adjusting points in which a nut is switched clockwise or counter clockwise to move the motor forward or backward. As the electric motor 
moves forwards during adjustment the drive pressure reduces as the sheaves (pulleys) move nearer to each other. Conversely, as the electric motor techniques backward the sheaves move additional away from one another and pressure on the belt boosts. The U.S. Department 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 is not periodically re-tensioned.”
The second type of motor base can be an automatic or Engine base. A popular style is a spring-loaded version that immediately adjusts for changes in center distance. When a electric motor operates, the starting torque causes the drive to flex somewhat forward as soon as inertia is conquer it rebounds into placement. Automatic tension-managed bases with a springtime design act as a constant resistant power that ensures the motor’s v-belt drive is constantly under adequate tension.
System Performance 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 increase runtime or reduce occupancy comfort.
2. Decreased power transmission performance 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 electric motor energy consumption
Think about this a Goldilocks and the 3 Bears analogy. The perfect belt tension is the point in which you have minimal slide and proper power transmitting, producing correct airflow with the minimum energy necessary to do so. The result is the belts operate at the perfect nominal temperature. Any other thing more or much less would either be too hot or too cold for Goldie.
Achieving and regularly maintaining this degree of tension when utilizing a fixed-position base could be a difficult job. It requires proper installation and periodic maintenance guidelines to make sure that the belt drive maintains an adequate degree of efficiency. Manufacturers’ suggestions for setting up belts and re-tensioning are to “Examine tension frequently through the first a day of operation. Check after jog begin or 1-3 minutes of operation, at 8 hours, 24 hours, 100 hours and periodically thereafter are recommended”.
Electric motor Bases are fabricated of metal which offers a bottom of rugged design, small and smooth to look at. Bases are style to provide adequate travel, are completely adjustable by the use of a single adjusting screw and have elongated installation holes in the base plate.

Adjustable Electric motor Bases are weighty gauge steel installation bases made to simplify installing motors and make the tensioning, maintenance and reMotor base china placement of belts a simple efficient task. Fabricated from sheet or steel plate, after that primed and finished in a gray rust and corrosion resistant oven-baked finish. Gussets and reinforcing stations on larger units and constant seam welding on all products give these bases power and durability for an extended life. An individual (215T frame and smaller) or double (NEMA 254T frame and bigger) zinc plated adjusting screw is definitely provided. Motor installation bolts are included. Adjustable electric motor bases are created to attach to your existing motor’s base.
Make use of these bases to tension motor belts where the electric motor can be above or below the drive device. They allow easy access to adjustment screws on top of the plate. Belt tension can be adjusted without loosening the engine hold-down bolts. Alignment is preserved when changing belts. These bases are suitable for blower, compressor, lover, mixer, and pump applications where belt adjustment is necessary. Note: Not really for ceiling or side wall installations.
Check out ever-power wide selection of motor mounting bases that will help placement motors and adapt 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, automatic motor bases, resilient ring installation bases and more in an array of configurations.
