But what was our great idea? We wanted to introduce our MMA technology for valves as a piëzo/pneumatic replacement. Our idea was well received, because we started a partnership with HAWE Hydraulic. Together, we will implement our technology in their hydraulic systems!
The official kick-off of our project will be on January 13th. After this, we will have untill April 23th to work on the project. And in April, we will present our achievements with HAWE Hydraulic.
In 1999, the European Commission established different efficiency classes for electric motors to reduce energy consumption and to create awareness among various industries to the importance of a more sustainable environment. These efficiency classes were called the EFF standards. However, in 2008 these EFF standards changed to the current IEC standards for electric motors to overcome the international inconsistencies in regulations between electric motor standards and efficiency classes. For example, the US established the NEMA standards for electric motors, which differed a lot from the EU standards. new commission called the International Electrotechnical Commission (IEC) set these standards.
IE4 MOTORS BY MAGNETIC INNOVATIONS
The torque motors designed and manufactured by Magnetic Innovations already fall within the IE4 super premium efficiency class. This can result in enormous energy savings for your operations. For more info about the torque motors, contact us.
IEC EFFICIENCY CLASSES
The following IEC standards were established in 2008:
Since 2014, the power range was extended for electric motors and was set between 0,12 kW and 1000 kW. Furthermore, electric motors with a rated output of 0,75-375 kW must meet either IE3 efficiency or IE2 if fitted with VSD’s since the first of January 2017.
INTERNATIONAL ELECTRIC MOTOR EFFICIENCY STANDARDS
The following table shows a comparison between the in 2008 established IEC standards (IEC/EN 60034-20-01) and other international norms:
ELECTRIC MOTORS INCLUDED BY THE IEC STANDARDS
Single speed electric motors (single and three phase), 50 and 60 Hz
Line-start permanent magnet motors
2, 4, 6 or 8 poles – Rated output PN from 0.12 kW to 1000 kW
Rated voltage UN above 50 V up to 1 kV
Motors, capable of continuous operation at their rated power with a temperature rise within the specified insulation temperature class
ELECTRIC MOTORS EXCLUDED BY THE IEC STANDARDS
Motors designed to operate wholly immersed in a liquid
Brake motors, when the brake cannot be dismantled or separately fed.
Single-speed motors with 10 or more poles or multi-speed motors
Motors completely integrated into a machine (for example, pump, fan or compressor) that cannot be tested separately from the machine.
Motors specifically designed to operate:
At altitudes exceeding 4000 meters
Where ambient air temperatures exceed 60°C
In maximum operating temperatures above 400°C.
Where ambient air temperatures are less than –30°C (any motor) or less than 0°C (water-cooled motors)
Where the water coolant temperature at the inlet to a product is less than 0°C or exceeds 32°C
In potentially explosive atmospheres as defined in Directive 94/9/EC
At Magnetic Innovations we constantly try to improve our products. For example, we always look for opportunities for improvement on efficiency, power density or torque for our motors and actuators. But next to these factors, the noise level is also becoming increasingly important. Everyone wants a silent motor, right? To improve this and build more quiet motors with direct drive technology, it is important to know what the current noise level is.
To that end, Magnetic Innovations has purchased a sound-suppressing measuring booth with a number of omnidirectional calibrated microphones. This allows us to perform very accurate noise measurements, to determine what the current noise level is at each frequency. We can also analyze where certain resonances occur. We can introduce this in our simulation models and that gives us new insights and tools to make our products even better! In addition, we can also quickly and properly assess new motor concepts and configurations on their noise level. This way we continue to do our best to meet all your requirements.
