Article Abstract – This article will explore the various types of industrial Ever-power motor bases and the vast variations they have in maintainability and supreme drive efficiency. An in depth analysis of a Motor base motor foundation technology compared to industry standard (threaded bolt adjustment) bases will emphasize the energy savings, overall performance improvement and payback of retrofitting with a Motor base.

In Ever-power belt driven applications, belt tension represents a significant little bit of the system’s overall efficiency. That efficiency can be adversely affected by belt slippage or excess pressure. How that belt drive is definitely installed and managed 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 1st category is actually a fixed-position foundation. These bases typically have a couple of adjusting points in which a nut is turned clockwise or counter clockwise to go the motor forward or backward. As the motor moves ahead during adjustment the drive tension reduces as the sheaves (pulleys) move nearer to each other. Conversely, as the engine moves backward the sheaves move further away from one another and tension on the belt boosts. The U.S. Division 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 Electric motor 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 as soon as inertia is get over it rebounds into placement. Automatic tension-managed bases with a spring design act as a constant resistant force that guarantees the motor’s v-belt drive is continually under adequate tension.

System Performance vs Proper Belt Tension

Under-tensioned belts lead to slip between your driver sheave and the driven. The outcome of this is:
1. Decreased airflow, that may either increase runtime or reduce occupancy comfort.
2. Decreased power transmission effectiveness and improved belt temperature because of 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

Consider this a Goldilocks and the 3 Bears analogy. The perfect belt tension is the point where you have minimal slide and proper power transmission, producing correct airflow with the minimal energy necessary to do so. The result is the belts operate at an ideal nominal temperature. Anything more or less would either end up being too hot or too frosty for Goldie.
Achieving and consistently maintaining this degree of tension when using a fixed-position base could be a difficult job. It requires proper set up and periodic maintenance best practices to make sure that the belt drive maintains an adequate degree of efficiency. Manufacturers’ recommendations for installing belts and re-tensioning are to “Check tension frequently during the first a day of procedure. Check after jog start 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 base of rugged design, compact and smooth to look at. Bases are design to provide adequate travel, are completely adjustable by the utilization of an individual adjusting screw and also have elongated installation 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 straightforward 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 channels on larger products and continuous seam welding on all models 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 motor bases are created to install to your existing motor’s base.
Use these bases to stress motor belts where in fact the motor is certainly above or below the drive unit. They allow quick access to adjustment screws along with the plate. Belt pressure can be adjusted without loosening the motor hold-down bolts. Alignment is managed when changing belts. These bases are suitable for blower, compressor, enthusiast, mixer, and pump applications where belt adjustment is required. Note: Not really for ceiling or aspect wall installations.
Check away ever-power wide range of motor mounting bases that can help placement motors and adapt belt tension during set up and maintenance of shaded-pole and PSC motors used in fans, blowers, direct-drive heating system and AC applications and more. Find adjustable metal bases, pivot bases, automatic motor bases, resilient band mounting bases and more in an array of configurations.
