SIMOTICS HV AboveNEMA Motors

Brand: Siemens AG

Medium and high voltage induction motors for challenging applications.

Horizontal AC induction motors up to 20 MW (27,500 HP) and AC vertical motors up to 6 MW (8,000 HP) with voltage ranges from 460 to 13,200 V for a wide range of heavy industrial applications.
Features
  • Stator systems
    • Form wound stator insulation systems, featuring sealed epoxy mica designs, provide the ultimate in electrical protection and mechanical strength meeting and exceeding NEMA MG1-20 standards. They allow for motors to excel in adjustable frequency drive applications, and handle high switching speeds or reversing requirements. Stator core laminations are punched from high grade C5 core plate silicon steel for optimum electrical and magnetic performance
  • Rotor systems
    • Proven rotor systems, are engineered with robust medium carbon steel shafts and high-grade aluminum or copper materials to reliably and efficiently transmit heavy loads, have axial vents in the core laminations to cool the core, and are dynamically balanced at full operating speed to minimize noise and vibration
  • Frame system
    • High-grade cast iron and fabricated steel frames are precision-machined to assure precise rotor and stator alignment for long bearing life, low vibration, and harmonics
  • Bearing systems
    • Anti-friction (ball) and sleeve bearings have labyrinth seals on both ends and are vented to prevent lubricant migration. They are insulated on both sides to prevent shaft current damage. Sight gauges and constant level oilers are available to monitor and maintain lubricant levels
