SIMOTICS S-1FT7 motors, forced ventilation, water cooling and natural cooling

The SIMOTICS S-1FT7 motors are permanent-magnet synchronous motors with very compact dimensions and an optically attractive design.

The 1FT7 motors fulfill the highest demands on dynamic performance, speed setting range, shaft and flange accuracy. They are equipped with state-of-the-art encoder technology and optimized for operation on our fully digital drive and control systems. Natural cooling, forced ventilation or water cooling are available as cooling types. With the natural cooling method, heat is dissipated through the surface of the motor, whereas with the forced ventilation method, heat is forced out by means of built-on fans.

Maximum cooling, and thus maximum power ratings can be achieved using water cooling.

Характеристика



Torque characteristic of a synchronous motor operating on a converter
with field weakening (example characteristic)

Особенности


  • Excellent dynamic performance in a wide speed range thanks to high overload capability ≥ 4 × M0 with natural cooling
  • Wide speed setting range
  • High robustness against vibratory and shock loads thanks to vibration-isolated encoder mounting
  • High degree of protection – allows operation even withdemanding ambient conditions
  • Quick and easy mounting due to cross-profile and rotatable connectors with quick-release locks
  • Zero-backlash holding brake
  • Extremely high efficiency

SIMOTICS S-1FT7 Compact motors

Due to their low torque ripple, 1FT7 Compact motors are especially suited for use in machine tools that require maximum surface quality and optimum machining quality. Their compact dimensions permit mounting in confined spaces.

SIMOTICS S-1FT7 High Dynamic motors

1FT7 High Dynamic motors have very low rotor moments of inertia to achieve extremely good dynamic performance and very short cycle times. As the motors are available with forced ventilation and with water cooling, they possess high continuous performance capabilities.

Дальнейшая информация



Some 1FT7 Compact motors are available as core types. These core types can be express delivered as replacement motors in the event of plant outages and offer the advantage of a quicker spare parts supply. For this reason, core types should be used for configuration wherever possible.

The selection and ordering data for the SINAMICS S120 Motor Modules are based on the booksize format by way of example. Other formats are also possible. The SIZER for Siemens Drives engineering tool is available for detailed configuration.
