Driving fluid flow engines towards the ultimate productivity

Improve energy efficiency with synchronous-reluctance drive systems. . About 97% of the lifecycle costs of motors can be attributed to energy expenses. Moving to a synchronous-reluctance drive system is just one small step, but the impact is huge, especially during partial load. The high efficiency ensures minimal operating costs and energy optimization, a short payback period, and a fast return on investment.

Efficiency perspective

Focusing on efficiency

Synchronous-reluctance drive systems allow high productivity with minimum operating costs thanks to extremely low power consumption.

Cost-effective and energy-efficient implementation of pumps, fans, and compressors.

A synchronous-reluctance drive system operates at an astonishing level of energy efficiency and additionally offers greater power reserves than a comparable asynchronous drive. Especially in comparison with conventional asynchronous technology, a synchronous-reluctance drive system enables a very high level of efficiency in full and partial load range while maintaining high power density and a dynamic response. That lowers costs and conserves energy.

Be on the cutting edge

A drive system with a SIMOTICS reluctance motor not only achieves maximum energy efficiency at the rated operating point, similar to IE4, but can significanly increase efficiency in the partial load range compared with converter-based induction motors.

Improved productivity

The synchronous-reluctance drive system features high control dynamics and high speed stability in encoderless operation. That means productivity improvements and saves costs for encoders and cables.

Technical perspective

Focusing on technical benefits

Drives with synchronous-reluctance technology are characterized by very high levels of efficiency, particularly at part load. As an integrated drive system, the reluctance motor and inverter are carefully coordinated and enable a particularly economical operation.

Simply get started and reap the benefits

The motor code makes commissioning particularly fast and easy. The code number is located on the rating plate of the motor. Once the code is entered on the IOP operator panel of the SINAMICS frequency converter, the most important parameters are predefined. That saves time and eliminates mistakes. Application-specific parameters can be added manually by IOP, STARTER software or the SINAMICS Startdrive software (integrated in TIA Portal). That helps to facilitate commissioning.

Easily implement guidelines

The system efficiency of an integrated synchronous-reluctance drive system from Siemens is significantly higher than the minimum requirements of IES2, the highest defined system efficiency class. Energy efficiency increases thanks to the optimization of complete drive systems, as required by the European energy-related product standard EN 50598. The synchronous-reluctance drive system already achieves nearly its highest efficiency value in IES2 under loads starting at about 25% of the nominal torque.

More than just a drive system

The combination of a SIMOTICS reluctance motor and SINAMICS converter is unparalleled: In an Integrated Drive System, reluctance motors and converters are specifically coordinated to work together and provide for particularly cost-effective operation. Significant efficiency benefits can be seen as a result of the seamless integration into automation as well as through efficient engineering and service concepts across the entire lifecycle.

Economic perspective

Focusing on economics

Approximately 97% of the life cycle costs are motor-based energy costs. But there are alternatives out there that pay off.

Drive technology that pays off fast

The benefits of the synchronous-reluctance drive system include investment security, reduced operating costs, and rapid amortization. When compared to standard induction motors in IE2, the higher initial investment paid off in less than 12 months, when compared to a drive system with an IE3 motor it even paid for itself after five months with a pump load cycle in accordance with the standardized profile "Blue Angel" in two-shift operation and energy costs of 8 ct/kWh.
