Mechatronic Drive System
MOVIGEAR^® – Economic Efficiency

Greater energy efficiency for reducing energy and operating costs
Using opportunities to save energy is not only an important contribution to conserve the environment, it also pays off financially. In many industries, such as the automotive, food and beverage industries, airport logistics or general transport logistics, the topic "Total Cost of Ownership (TCO)" is becoming increasingly more important. Already in the planning stage, energy efficiency has become a focal point of an integrated approach. This also affects the development of modern drive technology. The drive technology used and its overall efficiency play a major role in this approach. The German Electrical and Electronics Manufacturers' Association ZVEI calculated that electrically powered systems account for more than two thirds of the industrial power consumption.

A simple formula illustrates this: Pinput = Peffective + Plosses

This means that the costs for electrical energy input Pinput are calculated from the effectively needed mechanical energy Peffective plus losses Plosses resulting from the overall efficiency.

Irrespective of the type of application or system, energy costs can only be reduced if energy losses during plant operation are kept as low as possible.

This is why more and more system operators invest in the latest development from SEW-EURODRIVE. For them, the mechatronic drive system MOVIGEAR^® is not only an investment in future-oriented and intelligent drive technology, but it also helps them to reduce energy costs immediately.

Take the motor efficiency of MOVIGEAR^®, for example, which already today significantly exceeds efficiency class IE4 (Super Premium Efficiency) that is currently being discussed as a draft in the IEC. The overall efficiency of MOVIGEAR^®, of gear unit, motor and drive electronics, is thus considerably greater than that of conventional drive solutions and contributes substantially to the reduction of energy losses during system operation.

Minimized drive losses

Energy-saving properties Efficiency optimized parallel shaft helical gear units Permanent-fluid synchronous motor to achieve the highest motor efficiency level Increased efficiency due to new electronics components and adjusted control modes DynaStop®deceleration function: No power consumption by releasing the mechanical brake High overload capacity allows for application-specific dimensioning – less installed system power with highest overall efficiency

The higher costs of the drive components, compared to conventional drive solutions, are compensated within one or two years only by the saved energy expenses.

A current calculation example from a large bottling plant shows that the total efficiency of a drive solution with MOVIGEAR^® is 10...25 percent higher than that of conventional drive solutions, depending on the used gear unit type and the operating point. If the 105 frequency-controlled standard gearmotors in this application, with a power rating between 1.1 and 2.2 kW, were replaced by corresponding MOVIGEAR^® units, the energy costs could be reduced by 15% and 30% on average.

Reducing energy costs by increasing overall efficiency

Using MOVIGEAR® is not only an active contribution to conserving resources and the environment, but also enables the system operator to save a substantial amount of costs. More energy saving aspects: The energy efficiency of MOVIGEAR® makes a sustainable contribution to the reduction of CO2 emissions and thus actively protect the environment. MOVIGEAR® significantly reduces the reactive power consumption compared to motors operated directly on the supply system and thus helps to ensure compliance with reactive power limit values. to the top
