Article Abstract – This content will explore the different types of industrial Ever-power electric motor bases and the vast distinctions they have in maintainability and best drive efficiency. An in depth analysis of a Engine base motor base technology compared to industry standard (threaded bolt adjustment) bases will highlight the energy savings, functionality improvement and payback of retrofitting with a Engine 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 extra stress. How that belt drive can be installed and maintained is normally a function of the ease of usage of the motor base.
Commercial Ever-power Motor bases typically fall into two categories. The first category is known as a fixed-position foundation. These bases routinely have one or two adjusting points where a nut is Motor base china turned clockwise or counter clockwise to go the motor ahead or backward. As the motor moves forward during adjustment the drive stress decreases as the sheaves (pulleys) move closer to each other. Conversely, as the motor movements backward the sheaves move further away from each other and tension on the belt increases. 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 kind of motor base can be an automatic or Motor base. A popular design is a spring-loaded edition that instantly adjusts for adjustments in center distance. Whenever a motor operates, the beginning torque causes the drive to flex somewhat forward and once inertia is get over it rebounds into position. Automatic tension-controlled bases with a spring design become a constant resistant force that guarantees the motor’s v-belt drive is continually 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 effectiveness and improved belt temperature due to the friction due to the slippage.
3. Decreased overall component 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 Three Bears analogy. The ideal belt tension may be the point where you have minimal slip and proper power tranny, producing appropriate airflow with the minimal energy required to do so. The effect may be the belts operate at an ideal nominal temperature. Anything more or less would either become as well hot or too cool for Goldie.
Achieving and consistently maintaining this level of tension when using 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 keeps an adequate level of efficiency. Manufacturers’ recommendations for installing belts and re-tensioning are to “Check tension frequently during the first 24 hours of operation. Check after jog start or 1-3 mins of operation, at 8 hours, a day, 100 hours and periodically thereafter are recommended”.
Motor Bases are fabricated of steel which offers a foundation of rugged design, compact and smooth in appearance. Bases are design to provide sufficient travel, are fully adjustable by the usage of an individual adjusting screw and also have elongated mounting holes in the bottom plate.

Adjustable Engine Bases are heavy gauge steel mounting bases designed to simplify the installation of motors and make the tensioning, maintenance and replacement of belts a straightforward effective task. Fabricated from sheet or steel plate, then primed and completed in a gray rust and corrosion resistant oven-baked complete. Gussets and reinforcing channels on larger devices and constant seam welding on all units give these bases strength and durability for a long life. A single (215T frame and smaller sized) or double (NEMA 254T frame and larger) zinc plated 
adjusting screw is provided. Motor mounting bolts are included. Adjustable engine bases are designed to install to your existing motor’s base.
Use these bases to pressure motor belts where in fact the motor is above or below the drive device. They allow quick access to adjustment screws along with the plate. Belt stress can be altered without loosening the electric motor hold-down bolts. Alignment is definitely managed when changing belts. These bases are ideal for blower, compressor, fan, mixer, and pump applications where belt adjustment is required. Note: Not for ceiling or aspect wall installations.
