Driving fluid flow engines towards the ultimate productivity

Improve energy efficiency with synchronous-reluctance drive systems

Focusing on efficiency

Synchronous-reluctance drive systems features high control dynamics and high speed stability in encoderless operation and 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 Innomotics reluctance motor not only achieves maximum energy efficiency at the rated operating point, similar to IE4 or even IE5, but can significantly increase efficiency in the partial load range compared with converter-based induction motors.

The way to fast, efficient operation. A perfectly harmonized solution

Digitalization is becoming more and more prominent in all industries. Thus, the new generation of synchronous-reluctance systems offers powerful advantages to obtaining the necessary information from motors. Thanks to the knowledge gained, production can be strengthened and driven forward in a targeted manner. The Digital Twin and the SIMOTICS Digital Data App are the key to the digitized world of synchronous-reluctance drive systems.

Digital Twin means more than just simplifying processes

With Digital Twin, industries are able to use the power of digitalization to achieve optimum of performance. Higher efficiency and quality is achieved through less effort and costs. The Digital Twin contains a collection of all statically relevant product data, such as 2D drawings, 3D files, performance data or certificates. A lower susceptibility to errors during project planning and faster commissioning are only some of the resulting advantages. With these, the Digital Twin lays the foundation for adding value for the future system simulation models.

At a glance - The SIMOTICS Digital Data App

Digitalization enables information to be seen through our mobile devices. With the SIMOTICS Digital Data App, you constantly have access to electrical and mechanical data that you can easily obtain by scanning the DataMatrix-Code applied to the motor. By using mobile devices, it is possible to make processes more efficient, create transparency and simplify commissioning and assembly. They also benefit from optimized service activities. Even after commissioning has been completed, the app offers the enabling of optimum maintenance by simply ordering spare motors and parts.

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. 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.

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 Innomotics 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 Innomotics 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 Innomotics 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.

Focusing on economics

Approximately 97% of the life cycle costs are motor-based energy costs. The high efficiency of synchronous-reluctance drive system ensures minimal operating costs and energy optimization, a short payback period, and a fast return on investment.

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.
