Article Abstract – This article will explore the different types of industrial Ever-power motor bases and the vast distinctions they possess in maintainability and ultimate drive efficiency. An in depth analysis of a Engine base motor base technology compared to industry standard (threaded bolt adjustment) bases will emphasize 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 excess stress. How that belt drive is installed and taken care of is typically a function of the ease of utilization of the motor base.
Commercial Ever-power Electric motor bases typically fall into two categories. The 1st category is known as a fixed-position foundation. These bases typically have a couple of adjusting points where a nut is switched clockwise or counter clockwise to move the motor ahead or backward. As the engine moves forwards during adjustment the drive pressure decreases as the sheaves (pulleys) move closer to each other. Conversely, as the engine techniques backward the sheaves move additional away from each other and tension on the belt boosts. The U.S. Section of Energy publishes that notched v-belt drive performance “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 type of motor base can be an automatic or Motor base. A popular style is a spring-loaded edition that automatically adjusts for changes in center distance. Whenever a motor operates, the starting torque causes the drive to flex somewhat forward and once inertia is overcome it rebounds into position. Automatic tension-managed bases with a springtime design act as a constant resistant power 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 driven. The results of this is:
1. Decreased airflow, which can either boost runtime or reduce occupancy comfort.
2. Decreased power transmission effectiveness and increased belt temperature because of the friction caused by the slippage.
3. Decreased overall element life.
Alternatively, more than tensioned belts bring about:
1. Decreased bearing life
2. Excessive heat generation
3. Increased electric motor energy consumption
Consider this a Goldilocks and the 3 Bears analogy. The perfect belt tension may be the point where you have minimal slip and proper power transmission, producing correct airflow with the minimal energy required to do so. The effect may be the belts operate at the perfect nominal temperature. Any other thing more or much less would either become too hot or too chilly for Goldie.
Achieving and consistently maintaining this level of tension when using a fixed-position base can 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’ recommendations for setting up belts and re-tensioning are to “Examine tension frequently through the first a day of procedure. Check after jog start or 1-3 mins of operation, at 8 hours, a day, 100 hours and periodically thereafter are recommended”.
Engine Bases are fabricated of metal which offers a bottom of rugged design, compact and smooth in appearance. Bases are design 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 heavy gauge steel installation bases made to simplify installing motors and make the tensioning, maintenance and replacement of belts a straightforward effective task. Fabricated from sheet or steel plate, after that primed and finished in a gray rust and corrosion resistant oven-baked finish. Gussets and reinforcing channels on larger devices and constant seam welding on all systems give these bases strength and durability for a long life. An individual (215T frame and smaller sized) or double (NEMA 254T frame and bigger) zinc plated adjusting screw is provided. Motor mounting bolts are included. Adjustable electric motor bases are designed to attach to your existing motor’s base.
Use these bases to tension motor belts where in fact the motor is above or below the drive unit. They allow easy access to adjustment screws along with the plate. Belt stress can be altered without loosening the engine hold-down bolts. Alignment can be taken care of 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 part wall installations.
Check away ever-power wide range of motor mounting bases which will help placement motors and change belt tension during set up and maintenance of shaded-pole and PSC motors found in fans, blowers, direct-drive heating and AC applications and more. Find adjustable metal bases, pivot bases, automatic motor bases, resilient band installation bases and more in an array of configurations.
