Motor base

Article Abstract – This content will explore the different types of commercial Ever-power electric motor bases and the vast variations they possess in maintainability and supreme drive efficiency. An in depth analysis of a Electric motor base motor foundation technology in comparison to industry regular (threaded bolt adjustment) bases will highlight the energy savings, overall performance improvement and payback of retrofitting with a Engine base.

In Ever-power belt driven applications, belt tension represents a substantial little bit of the system’s overall efficiency. That efficiency could be adversely suffering from belt slippage or excess pressure. How that belt drive is usually installed and preserved is normally a function of the simple use of the motor base.

Commercial Ever-power Engine bases typically fall into two classes. The initial category is known as a fixed-position foundation. These bases routinely have a couple of adjusting points where a nut is switched clockwise or counter clockwise to move the motor forward or backward. As the electric motor moves ahead during adjustment the drive stress reduces as the sheaves (pulleys) move nearer to each other. Conversely, as the engine movements backward the sheaves move additional away from each other and stress on the belt raises. The U.S. Section 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 because the belt is not periodically re-tensioned.”

The second kind of motor base can be an automatic or Engine base. A popular design is a spring-loaded version that immediately adjusts for adjustments in center distance. When a motor operates, the beginning torque causes the drive to flex slightly forward and once inertia is conquer it rebounds into position. 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 powered. The results of this is:
1. Decreased airflow, which can 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 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 Three Bears analogy. The ideal belt tension is the point where you have minimal slip and proper power tranny, producing appropriate airflow with the minimum energy required to do so. The effect is the belts operate at the perfect nominal temperature. Anything more or much less would either end up being too hot or too frosty for Goldie.
Achieving and consistently maintaining this level of tension when using a fixed-position base can be a difficult task. It requires proper installation and periodic maintenance best practices to ensure that the belt drive maintains an adequate degree of efficiency. Manufacturers’ suggestions for installing belts and re-tensioning are to “Examine tension frequently during the first a day of operation. Check after jog begin 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 bottom of rugged design, small and smooth to look at. Bases are design to provide adequate travel, are fully adjustable by the use of a single adjusting screw and also have elongated mounting holes in the base 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 simple effective task. Fabricated from sheet or steel plate, after that primed and completed in a gray rust and corrosion resistant oven-baked complete. Gussets and reinforcing channels on larger products and constant seam welding on all models give these bases power and durability for an extended life. An individual (215T frame and smaller sized) or double (NEMA 254T frame and larger) zinc plated adjusting screw is provided. Motor installation bolts are included. Adjustable electric motor bases are designed to attach to your existing motor’s base.
Use these bases to pressure motor belts where the motor can be above or below the drive device. They allow easy access to adjustment screws on top of the plate. Belt stress can be modified without loosening the motor hold-down bolts. Alignment is definitely preserved when changing belts. These bases are suitable for blower, compressor, fan, mixer, and pump applications where belt adjustment is required. Note: Not for ceiling or part wall installations.
Check out ever-power wide selection of motor mounting bases that will help position motors and adapt belt tension during installation and maintenance of shaded-pole and PSC motors found in supporters, blowers, direct-drive heating and AC applications and more.
