European eco-design directives and minimum efficiency levels for motors
Minimum efficiency levels for electric motors and frequency converters for new systems
In October 2009, the EU adopted framework regulation 2009/125/EC.
"Directive establishing a framework for the setting of ecodesign requirements for energy-related products.
Another planned amendment to the Ecodesign Directive, to be adopted in 2027, relates to the sustainability of the materials used and their supply chains.
This is a major challenge for the industry. This means that the motors used must meet minimum efficiency requirements - efficiency classes IE1-5.
-> This is where we come in! We have the right drive technology for you!
Ready for IE5 today with synchronous reluctance technology
Classification of motor efficiency - Intelligent motor control
By using Mitsubishi Electric frequency inverters in combination with synchronous reluctance motors, you can achieve IE5 today!
This is particularly interesting for new purchases. There is no need for retrofitting when new directives come into force in the next few years.
Because if you automate today in accordance with the directives (which will definitely come!), you are already perfectly positioned for the future.
This means you can achieve the required IE5 classifications with little effort using existing technology.
A winning team - Inverters and synchronous reluctance motors
Our reluctance motor control mode, in conjunction with Mitsubishi Electric FR-F800 and FR-A800 series frequency inverters, as well as manufacturer-independent motors, successfully demonstrates potential savings.
The focus is
on variable speed fan and pump applications to achieve maximum efficiency.
A new take on a good idea
Our approach is to adapt existing synchronous reluctance motors with modern, innovative drive control technology.
In addition to efficiency, the decision in favour of reluctance motor technology is also a decision in favour of sustainability. This is because only copper and iron are used in production, and no rare earths.
What is a synchronous reluctance motor?
In short, a synchronous reluctance motor is an electric motor that operates without permanent magnets or short circuit bars in the rotor. It uses differences in magnetic resistance (reluctance) to generate torque.
With no rotor losses, it offers high efficiency and low heat generation. These motors
achieve high efficiency classes such as IE4 and IE5, making them
ideal for driving pumps, fans and compressors.
Innovative motor technology: The permanent magnet-free synchronous reluctance motor
The performance of the synchronous reluctance motor can be further optimised with a frequency inverter from Mitsubishi Electric. The motor works on the same principle as the permanent magnet synchronous motor, but does not use expensive rare earth magnets.
This means that the synchronous reluctance motor, in conjunction with the frequency inverter, also has the potential to achieve better efficiency in the partial load range.
What are the benefits of a synchronous reluctance motor?
Synchronous reluctance motors are highly efficient because there is no current in the rotor, which significantly reduces heat losses.
By eliminating the need for expensive materials such as permanent magnets, synchronous reluctance motors are often cheaper to manufacture. This can be particularly beneficial in applications where cost efficiency is critical.
Without the rare earths used in permanent magnet motors, synchronous reluctance motors are more environmentally friendly. This is particularly important in terms of sustainable production and disposal.
The reluctance motor is as easy to maintain as a three-phase asynchronous motor. The lower rotor temperature compared to a three-phase asynchronous motor also reduces thermal stress on the motor bearings, extending maintenance cycles.
Synchronous reluctance motors offer excellent control options due to their synchronous operation and the ability to control speed and position precisely using modern control technology.
