Abstract: A hydrostatic drive, to operate rotational industrial equipment such as a fan, a pump, a compressor, a conveyor or other drive used in industrial settings. The invention utilizes one or more variable displacement pump(s) configured to drive one or more fixed displacement hydraulic motor(s), or utilizing one or more fixed displacement pump(s) configured to drive one or more variable displacement hydraulic motor(s) or utilizing one or more variable displacement pump(s) configured to drive one or more variable displacement hydraulic motor(s). The pump(s) is powered by a fixed speed or variable speed motor or engine, most likely a fixed speed electric motor. The motor operates the rotational equipment with the purpose of process control, efficiency, and/or energy conservation.
