Energy costs are growing from year to year – the heating-oil bill or a visit to the filling station are constant reminders.Whether greenhouse effect, global warming or scare resources: Everything suggests that the environmental aspect too will keep the price spiral turning – and no end is in sight.Read More
In the case of drive systems, the energy costs are often as high as the acquisition costs after just a few years. Energy-efficient drive systems are often more expensive to buy than conventional drives. However, the extra costs are in most cases paid back in the space of a few years from the energy savings that are made.
Therefore, the cost efficiency of the drive system can only be assessed within the scope of life-cycle cost analysis (Life-Cycle Costs).Read More
Efficiency of gear units
The energy required can only be used effectively if the drive components employedoperate with ahigh level of efficiency.
Direct drives provide the highest level of efficiency as the drive motor works without any gear unit. However, drive units with chain gears are in many cases indispensable because a safety clutch is integrated in them.Read More
Problems in conveying
Today, the unwanted high level of friction in Conveyor systems leads to the following problems:
• the pulling medium (chain) is exposed to extreme levels of stress
• the sliding components build up high levels of heat.
This necessitates a high level of drive power. The energy efficiency of the drivecomponents is governed by:
• the efficiency ofthedrivecomponents
• the energyefficiency classofthemotors used.Read More
