We need to produce more food, not just for economic growth but also to feed the growing world population
We also need to get better at producing food in efficient ways. Farmers, manufacturers, retailers and consumers all have a part to play in reducing waste and using resources effectively. At the same time, we need to try to prevent the pressure we’re putting on the land, including through climate change, from damaging the environment.
Today’s challenging environments demand increasingly large and more powerful equipment across the entire mining process - and the need for efficiency and reliability grows
Power Conversion solutions are integrated throughout the mining process from extraction, mineral processing and material handling to improved reliability and power density. To meet the ever-increasing requirements of mining regulatory bodies engineers perform wider rating calculations, feasibility studies, control system updates, compliance tests and site inspections. High-speed mill solutions offer flexibility and efficiency through the use of rotor drives for slip energy recovery systems enabling speed adjustment. To meet the requirements for reduced loading and unloading times, supplies of complete electrical systems including fully integrated automation solutions, and a comprehensive range of drives for bulk handling systems are needed. High-performance induction motor systems helps provide significant reductions in service and maintenance costs, and higher efficiency levels rather than in geared solutions.
In recent years there has been a positive trend in the offshore sector toward the use of AC drilling drives rather than the once popular SCR (DC) based systems
An important milestone among the leaders in the drilling industry is the introduction of AC drives with variable frequency Pulse Width Modulation (PWM) drive. Typical drilling applications include:
- Top drives
- Mud pumps
- Cement pumps
The advanced AC drilling drives features includes high-accuracy speed and torque control combined with excellent dynamic characteristics across the speed range. Drilling drive systems should meet the applicable major international, marine and offshore standards including IEC, IEEE45, LRS, DNV, BV, GL, RMRS, ABS, KR, CCS AND RINA classification society rules and regulations.
