Article Abstract – This content will explore the different types of industrial Ever-power electric motor bases and the vast differences they possess in maintainability and ultimate drive efficiency. An in depth analysis of a Motor base motor base 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 substantial little bit of the system’s overall efficiency. That efficiency can be adversely suffering from belt slippage or excess pressure. How that belt drive is certainly installed and preserved is typically a function of the ease of use of the motor base.
Commercial Ever-power Engine bases typically fall into two classes. The initial category is actually a fixed-position base. These bases typically have one or two adjusting points where a nut is turned clockwise or counter clockwise to go the motor forwards or backward. As the motor moves forwards during adjustment the drive stress reduces as the sheaves (pulleys) move closer to each other. Conversely, as the engine moves backward the sheaves move additional away from one another and stress 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%) as time passes if slippage occurs because the belt is not periodically re-tensioned.”
The second kind of motor base is an automatic or Motor base. A popular design is a spring-loaded edition that immediately adjusts for changes in center distance. Whenever a electric motor operates, the starting torque causes the drive to flex somewhat forward and once inertia is get over it rebounds into position. Automatic tension-managed bases with a spring design act as a constant resistant pressure that guarantees the motor’s v-belt drive is constantly under adequate tension.
System Performance vs Proper Belt Tension
Under-tensioned belts result in slip between your driver sheave and the powered. The results of this is:
1. Motor base china Decreased airflow, that may either increase runtime or reduce occupancy comfort.
2. Decreased power transmission effectiveness and improved belt temperature because of the friction caused by the slippage.
3. Decreased overall component life.
Alternatively, more than tensioned belts bring about:
1. Decreased bearing life
2. Excessive heat generation
3. Increased engine energy consumption
Think about this a Goldilocks and the 3 Bears analogy. The ideal belt tension may be the point in 
which you have minimal slip and proper power tranny, producing appropriate airflow with the minimum energy required to do so. The result is the belts operate at an ideal nominal temperature. Anything more or less would either become too hot or too chilly for Goldie.
Achieving and consistently maintaining this degree of tension when using a fixed-position base could be a difficult job. It requires proper installation and periodic maintenance best practices to make sure that the belt drive maintains an adequate level of efficiency. Manufacturers’ suggestions for setting up belts and re-tensioning are to “Examine tension frequently during the first 24 hours of operation. Check after jog begin or 1-3 a few minutes of operation, at 8 hours, 24 hours, 100 hours and periodically thereafter are recommended”.
Engine Bases are fabricated of steel which offers a foundation of rugged design, compact and smooth in appearance. Bases are style to provide adequate 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 made to simplify installing motors and make the tensioning, maintenance and replacement of belts a simple efficient task. Fabricated from sheet or steel plate, after that primed and completed in a gray rust and corrosion resistant oven-baked finish. Gussets and reinforcing channels on larger products and continuous seam welding on all devices give these bases strength and durability for a long life. An individual (215T frame and smaller sized) or double (NEMA 254T frame and larger) zinc plated adjusting screw is certainly provided. Motor mounting bolts are included. Adjustable electric motor bases are made to install to your existing motor’s base.
Use these bases to pressure motor belts where in fact the electric motor is certainly above or below the drive unit. They allow quick access to adjustment screws on top of the plate. Belt pressure can be modified without loosening the motor hold-down bolts. Alignment is certainly preserved when changing belts. These bases are suitable for blower, compressor, enthusiast, mixer, and pump applications where belt adjustment is necessary. Note: Not for ceiling or part wall installations.
Check away ever-power wide selection of motor installation bases that will help position motors and modify belt tension during installation 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 ring installation bases and more in an array of configurations.
