SIMOTICS SD Severe Duty Motors – next generation

SIEMENS | INNOMOTICS SIMOTICS SD Shaft Height 315 - 355 / 400 - 450 (1LE5)

SIMOTICS SD next generation low-voltage motors are not only especially compact, efficient and reliable, but offer a further key advantage – they're ready for digitalization.

Because the motors are part of your digital enterprise, they enable you to optimize your processes. A new design provides high power density despite the smaller cover size.

We currently offer two variants: SIMOTICS SD and SIMOTICS SD Add. SIMOTICS SD features higher torque characteristics, while the SIMOTIC SD Add has lower starting currents and global certificates.

Significant energy savings potential can be achieved thanks to the future-oriented energy efficiency design.

Typical applications

  • Cement

  • Chemicals

  • Fiber

  • HVAC

  • Marine

  • Metals

  • Mining

  • Oil and gas

  • Water & waste water
