The SIMOTICS family of motors

With SIMOTICS, Siemens offers a comprehensive portfolio of electric motors. From energy-efficient, low-voltage motors through servomotors with high dynamic performance up to wellproven DC motors and powerful high-voltage motors. Innovative drive technology for all industries, applications and performance classes. Outstanding performance, quality, efficiency and compactness.

SIMOTICS – Low-voltage motors for mains-fed and converter-fed operation

SIMOTICS low-voltage motors for mains-fed and converter-fed operation are subdivided into seven segments depending on the particular application.

• General Purpose – SIMOTICS GP
  Motors for everyday applications in industry under standard environmental conditions.
• Severe Duty – SIMOTICS SD
  Motors with cast-iron housing for applications under harsh environmental conditions.
• Explosion Protected – SIMOTICS XP
  Motors for potentially explosive atmospheres.
• Definite Purpose – SIMOTICS DP
  Special motors, e.g. smoke extraction motors or built-in motors.
• Flexible Duty – SIMOTICS FD
  Converter-optimized motor series for flexible applications with higher outputs in the range of 200 kW to over 1600 kW, with various cooling methods. Water-cooled motors are also offered for mains-fed operation.
• Transnorm – SIMOTICS TN
  Motors with cast-iron housing with higher outputs in the range of 145 kW to 1250 kW.
• High Torque – SIMOTICS HT
  Permanent magnet synchronous motors for applications that require extremely powerful drives without gear unit, even at low speeds.

Performance features of the SIMOTICS FD series

The SIMOTICS FD series is characterized by the following features:

• Series of low-voltage motors optimized for converter-fed operation
• Three product lines
  • Air-cooled, enclosed version
  • Water-cooled version
  • Air-cooled, open version
• Wide output range from 125 kW to over 895 kW in frame sizes 315 and 355
• Rugged cast-iron housing

A wide range of water-cooled motors is also available for mains-fed operation.

The SIMOTICS FD motor series covers outputs from 200 kW and higher (at 1500 rpm), and is available in a version optimized for converter-fed operation with various cooling methods and as a water-cooled version for mains-fed operation.

This motor series has an extremely long service life, is rugged and ensures the highest availability thanks to various technical details. For instance, KTY 84-130 temperature sensors are integrated as standard in the winding as motor protection.

SIMOTICS FD motors are characterized by a very high output with a small frame size. The result of this is an extremely compact design that saves space in a number of industrial applications.

SIMOTICS FD motors are not only optimized in terms of their design, but also in terms of their efficiency, so they also contribute towards lower energy consumption.

The version optimized for converter-fed operation as part of a drive system is harmonized for operation with SINAMICS lowvoltage frequency converters. Together with SINAMICS, it forms an optimally harmonized drive system for variable-speed applications.
