Clever motor starting - Soft motor starting with SINAMICS and SIRIUS

The right drive solution for your application

Companies in all industrial sectors are faced with the challenge of ensuring the efficient operation of electric motors in a host of applications. Factors such as mechanical load, cost efficiency, compliance with standards, reliability, and improvement in energy efficiency need to be taken into account. In view of these challenges, it is often not easy to decide between a frequency converter and a soft starter.

Both ensure smooth, torque-controlled motor starting and prevent excessive torques that can result in premature damage to the components in the drive train and even in failure. Typical areas of use are pumps, fans, compressors, conveyor belts, belt drives or escalators.

Frequency converters as the solution

  • Ideal for flexible speed control to meet variable process parameters
  • Dedicated product functions and options for optimum adaption to a particular application
  • User-friendliness and flexibility

Soft starters as the solution

  • Compact and cost-efficient drive solution for fixed speed operation
  • Low maintenance requirement, additional accessories often not necessary
  • Integrated bypass function to reduce energy losses during operation, no additional heat generation

Whatever constraints you face, Siemens will offer you the best drive solution for your motor. Whether for efficient pumping, ventilating, and compressing, or precision moving, processing or machining, the number of applications where converters and soft starters can be used is almost endless. With our SINAMICS and SIRIUS portfolio, we can offer you the perfect solutions for your complex requirements. Our portfolio stands for integrated engineering, maximum energy efficiency, and user-friendly operation. See for yourself!
