Modern VSDs take advantage of new, higher efficiency motor designs, like synchronous reluctance motors (SynRM) that have no rotor losses. These motors operate with 40 percent lower losses compared to a conventional induction motor, so replacing old drives can make sense. According to ABB Drives, the lower losses allow motor construction in two […]
Most industries face the common challenges of reducing energy use whilst maintaining product quality and productivity. Productivity improvements drive up profits to satisfy stakeholders. On an industrial site with an electricity bill of £150,000 a year, about £100,000 may go on running motors. According to ABB Drives, the energy-saving benefits of energy-saving drives are well […]
Around 80 per cent of maximal torque at 90 per cent speed is an efficient duty point for a motor and drive system. However, it is often possible to find a more efficient duty point by exploring a wider range of options. According to ABB, this offers opportunities for a designer tasked with improving the motor […]
Most of the deaths or injuries that occur in a fire result from smoke inhalation and intoxication from poisonous gasses. Airflow control is important for smoke management and keeping injuries and deaths as well as building damage to a minimum. The ABB ACH580 override mode VSDs is an important tool for minimising the loss of […]
With their high reliability, we sometimes forget why electric motors fail and how avoiding this needs some simple TLC. Focussing on this important issue, ABB has an interactive online booklet examining the main reasons why electric motors fail and how to prevent it. They also identify the six main failure categories, and of these, bearing […]
