System and method for variable drive pump control

摘要: A pump control system and method employs a variable drive for controlling the speed of an AC electric motor driving cyclic load. real-time tuning frequency voltage input to allows controlled variation cycle The adjusts according desired characteristic different portions complete over multiple cycles rectifies poly-phase power provide source DC on bus periodically samples current across optimize operation. preselected voltage-frequency profile set parameters including torque point or range consistent with derived from load are provided substantially minimize regeneration, mechanical loading, energy consumption maximize production operational efficiencies. To speed, synthesized signals fed at appropriate required increase decrease speeds during significantly reduce requirements system.
