Siemens GP100 Series — NEMA Premium® Cast Aluminum or Cast Iron Rotors:
Siemens GP100 motor has a cast iron frame and bearing housings that utilize the same design philosophy that goes into the design of our renowned severe duty line of motors… ruggedness, reliability, performance and efficiency. The design provides high structural strength through the use of finite element analysis to strategically place material within each component to resist the effects of stress and vibration. Materials for resistance to corrosion are liberally used throughout for long life in a wide variety of industrial applications.
Cast iron construction for exceptional structural integrity, equipped with integrally cast feet and condensation drain holes. Lifting provisions are included for frames 180T to 256T. Unique frame fin design maximizes cooling. Die cast aluminum rotor that meets NEMA MG1 Table 12 - 12 efficiencies. Each die cast copper rotor assembly is dynamically balanced for extended bearing life, and includes a high-strength carbon steel (C1045) shaft for maximum rotor performance. Manufactured with premium electrical grade steel laminations and copper electrical magnet wire to lower losses for improved efficiencies. A unique stator core design lowers flux density while increasing cooling capacity. Large conductor cross section reduces resistance and lowers stator losses. Proprietary inverter-rated NEMA Class F non-hygroscopic insulation system with Class B temperature rise @ 1.0 S.F., provides an extra margin of thermal life. Varnish system application ensures maximum wire penetration to provide protection from moisture, corrosion and electrical shock. This insulation system meets or exceeds NEMA MG1 - 2010, Part 31 making all motors suitable for operation with variable frequency drives. A bi-directional, non-sparking fan is locked and keyed to the shaft. Its low-inertia design reduces windage losses, improves air flow, reduces noise and provides dependable cooling. Polycarbonate fan covers are provided on all frame sizes.
