The rising cost of energy is placing a considerable burden on plant and machine operators. KEB Automation provides various solutions and products that can help. In doing so, you reduce costs and help protect the environment.
With harmonic filters from KEB, users can reduce grid harmonics. The design of the filter enables grid-friendly energy consumption and offers numerous advantages in practice. For example, the harmonic filters not only have a compact, space-saving design, but also ensure a lower voltage drop compared to mains chokes. This is important because voltage drops lead to a reduction in the efficiency of a machine or system, and consequently to higher overall energy consumption. In addition, the use of the harmonic filters ensures an increased service life of the DC link capacitors.
Modern motors, lower expenditure
Saving energy with electric motors starts with the correct design of the motor for the respective application. Over-dimensioning leads to additional costs in the medium term, which can easily be avoided through forward-looking planning. KEB provides modern motors for various applications that have low consumption due to optimal speeds, particularly in combination with KEB drive controllers.
KEB ensures reduced power consumption by ensuring that current asynchronous motors with a rated power from 0.75kW meet the requirements of energy efficiency class IE3. Synchronous servo motors of the TA series from KEB also prove to be very efficient when designed accordingly.
DC coupling – powerful in a network
By exchanging the energy in the DC network, the regenerative energy can be used further in the system. Rather than burning up the energy, it is actively utilised in the user’s solution. In addition, there is the advantage that the feed paths of the drive controllers can be reduced by the DC supply. This makes installation easier and can contribute to the reduction in the number of components.
Bistable brakes – the low energy solution
KEB bistable brakes – also known as flip-flop brakes – can maintain ‘open’ and ‘closed’ switching states without any further energy supply. The advantages of bistable brakes are particularly evident when a position has to be held for a long time. This is the case, for example, with doors or flap systems. Another benefit is that due to the high energy savings, the bistable brakes are ideally suited to battery operation. In addition to zero energy consumption (except for the switching pulse) the bistable brakes allow simple system integration and backlash-free operation.
