Maximum power and performance with customized cooling

The SIMOTICS S-1FT7 servomotors are permanent magnet synchronous motors with highly compact dimensions for meeting the most stringent demands on precision, dynamics and speed setting range as well as on high degrees of protection and ruggedness. The motors are fitted with the latest encoder technology and are optimized for operation with Siemens fully digital drive and control systems. Three cooling types are available: natural, forced-ventilation or water-cooling. In the case of natural cooling, the developing thermal loss is drawn off via the surface area whereas an attached fan forces thermal loss away with forced vent cooling. Maximum cooling, and therefore, maximum performance, can be achieved with water-cooling.

Gear up for better servo solutions

The advantage concept of SIMOTICS S-1FG1 servo geared motors is simple: offer the most variable configuration options that can be used to create customized solutions — both in terms of construction and power rating. Whatever your application requires – high efficiencies, low torsional backlash or finely graduated ratios, these motors optimally address the widest range of motion control applications.

 

The SIMOTICS S-1FG1 servo gear motors have smaller dimensions, weigh less and have a higher dynamic response than standard induction geared motors. The range of types includes helical, parallel shaft, bevel and helical worm geared motors in the usual frame sizes and speed/torque classes. SIMOTICS S-1FG1 servo geared motors also use the same operating heads as SIMOGEAR geared motors.

 

These servo geared motors are optimally adapted to the SINAMICS S120 drive system and the various Siemens commissioning tools. This facilitates seamless integration into the drive and automation environment. Commissioning can be performed very quickly using the DRIVE-CLiQ system and electronic type plate. Pre-fabricated MOTION-CONNECT power and signal cables ensure that perfect connections can be established quickly and easily.

Powerful features & flexible configuration options

  • Extremely compact design as a result of direct mounting
  • High efficiency
  • Maintenance-free and lubricated for life (exception, worm gearing)
