  • A high performance and cost effective drive based power conditioner for critical applications
    Adjustable-speed drives (ASD) have revolutionized the industrial automation, leading to higher efficiency and productivity. Approximately 75% of all electric motor driven applications require a variable speed, variable torque or both [1], in industrial applications such as pumps, fans, compressors, cranes, paper mills, steel mills, rolling mills, elevators, machine tools, etc. The majority of ASD applications are satisfied with general-purpose induction motor drives using volts -per-hertz control [2], with a world market volume of $ 12 billion and an annual growth rate of 15% [3].
  • Downsizing by combustion engines
    Expediently, come the actuators electromagnetic here for insert that can be operated with the available board network voltage of 12 volts and need about 30 W or 10 W electric power in the active operation per cylinder (stand-By). Through the pulse charging, the high torques up to the idling speed can be maintained without it needs a length adjustment of the suction tubes. ...weaknesses concerning the Low-End-Torque as well as the available torque in the transient motor operation.
