Ever since the introduction of speed control for electrical motors in the late 19th century, Siemens has been at the leading edge of high-performance drive technology. Our continued investment in research and development and commitment to innovation for the benefit of our customers has ensured our leading position in the industry. High- performance drives are those that provide a high dynamic response with high precision. These may be stand-alone drives for demanding applications or drives used in coordinated multi-motor drive systems.
