In addition to providing variable the speed of motors, inverter drives can also be used to stop them quickly by applying a braking torque to the motor. The energy released during this process is normally absorbed by a braking circuit and dissipated through braking resistors in the form of heat However, regenerative variable […]
While an industrial enterprise may realise its pumping system could be more effective, what may not be obvious is that energy-efficient pumps can help reduce utility expenses. Here’s why. Electricity costs account for 40% of the total cost of ownership (TCO) of a pump. By following energy management best practices, a manufacturer can decrease […]
As considered earlier, EN 50598 is a standard that defines two new energy efficiency classifications for variable-speed drives. Here, ABB Drives UK Ltd explain in more depth how these efficiencies will be calculated. New methodology One of the helpful feature of EN 50598 is that it provides a methodology for measuring the efficiency of […]
Electric motors are part of our way of life: in the home, in industry and in commercial buildings. According to Schneider Electric, motors consume 30% of the energy of a building, and 60% of the energy of industries and infrastructures. In business, 85% of electric motors control pumps, fans and compressors and by reducing motor […]
Improving productivity involves the whole of the value chain, not just production. The value chain is a set of activities that a firm operating in a specific industry performs to deliver a valuable product or service to the market. How value chain activities are carried out determines costs and affects profits. The manufacturing value […]
