SIMOTICS FD Flexible Duty Motors

General description

In the power range from 200 kW upwards SIMOTICS FD is the basis for a complete, cost-effective system comprised of a motor and drive with a high power density. Using a wide range of versions, the motors can be flexibly and efficiently used in the widest range of applications and sectors. The motors are rugged and durable as a result of their cast iron frame. The water-cooled motors allow an extensive range of other applications to be addressed.

Customer benefits

Extensive range of cooling methods

With SIMOTICS FD, you simply adapt the cooling method to address your particular requirements. You can select between open and enclosed versions – with self-ventilation or forced ventilation. Further, there are also water-cooled versions with water jacket cooling or air-water heat exchangers.

Rugged and easy to connect

The following characteristic features make SIMOTICS FD a great choice when it comes to the original equipping and retrofit:

  • High power density but with low envelope dimensions

  • High overload capability

  • Low noise level

  • User friendly terminal box with diagonal split

  • Flexible terminal box position

  • Housing design with internal cooling fins

  • Various encoder systems

  • Wide range of options with various sector packages

  • Country- or sector-specific approvals

Cost-effective combination: SIMOTICS and SINAMICS

The combination of SIMOTICS FD and low-voltage frequency converter SINAMICS G120P Cabinet, SINAMICS G130, SINAMICS G150, SINAMICS S120, SINAMICS S120 CM or SINAMICS S150 is especially cost-effective as the motor and drive are precisely coordinated and harmonized with one another. The rated motor currents are adapted to the frequency converter output currents and the motor is designed for the rated frequency converter pulse frequency. This means that the drive is not overdimensioned, and an optimum voltage utilization is ensured with low noise emission when operated from SINAMICS G and SINAMICS S drives.

Integrated Drive Systems

We offer our highly efficient motors in terms of Integrated Drive Systems to ensure even more energy saving potential. Not only are they perfectly matched to frequency converters, but also to couplings and gear units and seamlessly integrated into the automation landscape. Integrated tools and service concepts over the whole life cycle are also part of it.
