Motor base

Article Abstract – This content will explore the various types of commercial Ever-power electric motor bases and the vast distinctions they possess in maintainability and ultimate drive efficiency. A detailed analysis of a Engine base motor base technology in comparison to industry regular (threaded bolt adjustment) bases will highlight the energy savings, efficiency improvement and payback of retrofitting with a Motor base.

In Ever-power belt driven applications, belt tension represents a significant piece of the system’s overall efficiency. That efficiency could be adversely suffering from belt slippage or excess stress. How that belt drive is usually installed and taken care of is typically a function of the ease of usage of the motor base.

Commercial Ever-power Electric motor bases typically fall into two classes. The first category is known as a fixed-position base. These bases typically have one or two adjusting points where a nut is switched clockwise or counter clockwise to move the motor ahead or backward. As the motor moves forwards during adjustment the drive tension decreases as the sheaves (pulleys) move closer to each other. Conversely, as the engine moves backward the sheaves move additional away from each other and pressure on the belt increases. The U.S. Division of Energy publishes that notched v-belt drive effectiveness “deteriorates by as much as 5% (to a nominal efficiency of 93%) over time if slippage occurs because the belt isn’t periodically re-tensioned.”

The second type of motor base is an automatic or Motor base. A popular style is a spring-loaded version that immediately adjusts for adjustments in center distance. When a electric motor operates, the starting torque causes the drive to flex somewhat forward and once inertia is conquer it rebounds into position. Automatic tension-controlled bases with a spring design become a constant resistant push that guarantees the motor’s v-belt drive is constantly 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, which can either enhance runtime or decrease occupancy comfort.
2. Decreased power transmission efficiency and increased belt temperature due to the friction due to the slippage.
3. Decreased overall element life.

Alternatively, over tensioned belts bring about:
1. Decreased bearing life
2. Excessive heat generation
3. Increased motor energy consumption

Think about this a Goldilocks and the 3 Bears analogy. The ideal belt tension may be the point where you have minimal slide 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 become too hot or too frosty for Goldie.
Achieving and consistently maintaining this level of tension when utilizing 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 degree of efficiency. Manufacturers’ recommendations for setting up belts and re-tensioning are to “Examine tension frequently during the first a day of operation. Check after jog start or 1-3 mins 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, small and smooth in appearance. Bases are style to provide adequate travel, are completely adjustable by the use of a single adjusting screw and also have elongated mounting holes in the bottom plate.

Adjustable Engine Bases are large 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 metal plate, then primed and finished in a gray rust and corrosion resistant oven-baked complete. Gussets and reinforcing channels on larger devices and constant seam welding on all devices give these bases strength and durability for an extended life. An individual (215T frame and smaller sized) or double (NEMA 254T frame and bigger) zinc plated adjusting screw can be provided. Motor installation bolts are included. Adjustable electric motor bases are designed to install to your existing motor’s base.
Make use of these bases to tension 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 adjusted without loosening the electric motor hold-down bolts. Alignment is usually maintained when changing belts. These bases are ideal for blower, compressor, fan, 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 will help placement motors and adjust belt tension during set up and maintenance of shaded-pole and PSC motors used in enthusiasts, blowers, direct-drive heating system and AC applications and more. Find adjustable steel bases, pivot bases, automated motor bases, resilient band installation bases and more in a wide range of configurations.
