Article Abstract – This article will explore the different types of industrial Ever-power engine bases and the vast distinctions they possess in maintainability and ultimate drive efficiency. An in depth analysis of a Electric motor base motor foundation technology compared to industry regular (threaded bolt adjustment) bases will highlight the energy savings, performance improvement and payback of retrofitting with a Electric motor base.
In Ever-power belt driven applications, belt tension represents a significant little bit of the system’s overall efficiency. That efficiency could be adversely affected by belt slippage or excess pressure. How that belt drive is installed and Motor base china managed is typically a function of the simple usage of the motor base.

Engine bases typically fall into two types. The first category is actually a fixed-position base. These bases routinely have one or two adjusting points where a nut is turned clockwise or counter clockwise to move the motor ahead or backward. As the engine moves forwards during adjustment the drive tension decreases as the sheaves (pulleys) move closer to one another. Conversely, as the motor movements backward the sheaves move further away from one another and tension on the belt raises. 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 is not periodically re-tensioned.”
The second type of motor base is an automatic or Motor base. A popular style is a spring-loaded version that automatically adjusts for changes in center distance. Whenever a electric motor operates, the starting torque causes the drive to flex slightly forward and once inertia is get over it rebounds into position. Automatic tension-controlled bases with a springtime design become a constant resistant pressure that guarantees the motor’s v-belt drive is constantly under adequate tension.
System Efficiency vs Proper Belt Tension
Under-tensioned belts result in slip between the 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 effectiveness and improved belt temperature because of the friction caused by 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
Consider this a Goldilocks and the Three Bears analogy. The ideal belt tension is the point in which you have minimal slip and proper power transmitting, producing appropriate airflow with the minimal energy necessary to do so. The effect may be the belts operate at the perfect nominal temperature. Anything more or much less would either end up being as well hot or too chilly for Goldie.
Achieving and regularly maintaining this degree of tension when utilizing a fixed-position base can be a difficult job. It requires proper set up and periodic maintenance best practices to make sure that the belt drive keeps an adequate level of efficiency. Manufacturers’ recommendations for installing belts and re-tensioning are to “Examine tension frequently during the first 24 hours of operation. Check after jog begin or 1-3 moments of operation, at 8 hours, 24 hours, 100 hours and periodically thereafter are recommended”.
Motor Bases are fabricated of steel which offers a foundation of rugged design, compact and smooth to look at. Bases are design to provide sufficient travel, are completely adjustable by the utilization of a single adjusting screw and also have elongated installation holes in the base plate.

Adjustable Motor Bases are weighty gauge steel installation bases made to simplify the installation of motors and make the tensioning, maintenance and replacement of belts a straightforward efficient task. Fabricated from sheet or steel plate, after that primed and finished in a gray rust and corrosion resistant oven-baked complete. Gussets and reinforcing channels on larger devices and continuous seam welding on all devices 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 can be provided. Motor mounting bolts are included. Adjustable motor bases are designed to mount to your existing motor’s base.
Make use of these bases to stress motor belts where the motor is usually above or below the drive device. They allow quick access to adjustment screws on top of the plate. Belt tension can be altered without loosening the motor hold-down bolts. Alignment is usually managed when changing belts. These bases are suitable for blower, compressor, enthusiast, mixer, and pump applications where belt adjustment is required. Note: Not for ceiling or side wall installations.
Check out ever-power wide range of motor installation bases which will help position motors and modify 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.
