AC motors

Siemens Energy & Automation has introduced three new lines of ac motors designed to meet or exceed NEMA standards. Offered in aluminum and cast iron frame configurations, these motors include high-efficiency and industry-leading NEMA Premium efficient designs to help motor users lower energy costs and extend service life. A unique die-cast copper rotor and special stator designs provide the added efficiency of these motors. The three new product lines include general purpose die cast aluminum, general purpose cast iron and severe duty cast iron frame motors for use in a wide variety of industrial applications. Siemens die cast aluminum frame motors have been developed to provide a high degree of mounting flexibility for general purpose applications such as air handling, conveyors, pumps and compressors. Cast iron frame motors are available for general purpose and severe duty applications. A definite-purpose version, exceeding the demanding requirements of the IEEE 841 standard, also is available for durability and energy efficiency in critical petroleum, chemical and paper processing environments.
