Unimec is marking a significant step in the ongoing pursuit of innovation and sustainability and this step is shared by our partnership. Unimec recently supplied four special-made screw jacks to a Norwegian shipping company with a strong reputation for its commitment to eco-friendly shipping. The project where these screw jacks will be used is one of the world’s first 100% electric ferryboat prototypes. A fact that makes Unimec, as a partner in ecological innovation, also important in the mobile sustainability transition. ...

Renewable energy is helping to reduce a large amount of harmful emissions released into the atmosphere and the world's dependence on fossil fuels. Biogas production through anaerobic maturation has always been an environmentally friendly energy source that helps generate green electricity. ...

At the last edition of EMAF, the International Trade Fair for Machinery, Equipment and Services for Industry, which took place from 1 to 4 December 2021 at the Exponor exhibition park, we had the opportunity to talk to Mechanical Engineer Manuel Oliveira, Technical Support at Reiman. He introduced us to Invertek Drives, a Reiman partner company focussed on the manufacture of frequency inverters for the command and control of electric motors. ...

Sometimes there are particular applications wich require complete reversibility, sometimes complete irreversibility of the worm and wheel gearbox. Therefore, this is why it is important to explain the behaviour of a worm and wheel gearbox when the rotation speed of the worm s reduced on the worm wheel. ...

A coupling is a mechanical component that connects 2 shafts which are intended to rotate in order to transmit power. Shaft couplings introduce some flexibility into mechanical transmission by providing tolerance to shaft misalignment. As a result, this coupling flexibility can reduce uneven bearing wear, equipment vibration and other mechanical problems due to misalignment. ...

Industrial Maintenance consists of a set of operational, technical, and administrative practices aimed at maintaining, replacing, or repairing parts or equipment that perform a function in industrial production processes. ...

Announced on 14 July, the European Commission established the European Green Deal to reduce net greenhouse gas emissions by at least 55% by 2030, compared to 1990 levels. This initiative is part of the implementation of the European Climate Law, which comes into effect this month (July 2021). The new law introduces stricter regulations on electric motors and Variable Frequency Drives (VFDs). ...

Electric motors have a very high energy cost due to the amount of energy they require to convert electrical energy into mechanical energy. Today, these devices are responsible for more than half of the world's industrial energy consumption. ...

The electric vibrating motor is used to convert electrical energy into mechanical energy to drive other vibrating equipment, in the most varied industrial branches. ...

The variable frequency drive is an electronic device designed to control the speed in alternating current electric motors. The speed variation is obtained by the conjugated variation of voltage and frequency of the current that arrives at the electric motor, according to a curve that, in turn, can also be changed by the drive itself. ...
