MOST EFFICIENT HYDROGEN CAR

 When it comes to making transport more environmentally sustainable, hydrogen is a key factor. The Netherlands is at the forefront when it comes to hydrogen innovation and they are constantly looking for ways to harness the full potential of this gas. In the Netherlands several buses run on hydrogen and they plan to increase this number. The University of Twente also contributes, they have been working on building the most efficient hydrogen car in the world for over ten years.

Every year the successful university team Green Team Twente builds a new hydrogen powered car. In 2012, 2017 and 2019 they became world champions with their hydrogen car during the international Shell Eco-Marathon Europe race. This race is about efficiency not speed. Green Team Twente is proud to say it has built one of the most fuel efficient hydrogen cars in the world. Converted to an efficiency of 760 km (472 miles) liter of fuel, equivalent to the distance from Zurich to Rotterdam.

For the time being, the June 2020 Eco-Marathon Europe race has been cancelled, Green Team Twente has made the decision to keep the development of the new hydrogen car going. They want to show the world what hydrogen powered vehicles are capable of and have set the goal to increase the efficiency of the car even more. The latest generation will be adjusted on the inside, allowing for more space and increasing the system accessibility.

The biggest change on the inside lies with the drive train, Magnetic Innovations and Green Team Twente decided to join forces and develop an in-wheel hub motor. The previous car had four electric motors with a gearbox. This will be replaced by the direct drive hub motor that is placed in the wheel of the car. This system drives the car without the use of a transmission and eliminates physical contact between stationary and moving parts. Thanks to the hub motor weight, maintenance and costs of the car are reduces. The in-wheel hub motor also increases the efficiency.

The team can be followed closely via their website www.greenteamtwente.nl. For more information about the in-wheel direct drive hub motor technology, please contact Magnetic Innovations.

Green Team Twente unveils design for their 2020 hydrogen car

Introduction of the new hydrogen car

On Tuesday, December 10, the design presentation of Green Team Twente took place in the Vrijhof at the University of Twente. The team has revealed the design, and with it all the changes, of the hydrogen car in which they will race at the Shell Eco-Marathon (SEM) Europe in London in July. They explained all the components separately in their presentation with the biggest changes being the new engine and the internal structure. We, Magnetic Innovations, help built this engine based on our torque motors.

The goal of this year’s design is to make the car more efficient, as well as more robust, reliable and user-friendly. This all, because the team has not only the goal to win the SEM, but also the sub goal to get the car road legal.

What has changed in the design of the car?

The big change is on the inside of the car where they placed fewer bulkheads. This way, there is more space and the systems become more accessible. The suspension is fully adapted to the new structure, but the biggest change lies with the engine. The team reintroduces a hub engine in the car. They go from the gearbox system, powered by 4 electric motors, to one hub motor. A hub motor is a motor that sits in the wheel, which means that there are no losses in the power transfer. The team made no radical changes to the hydrogen system and the strategy. They have further optimized these systems and made them more reliable, however.

With all this, Green Team Twente expects to win the Shell Eco-Marathon for the second year in a row. In the coming weeks, the entire team will work very hard to bring all these designs to life. You can come and see the finished car yourself at the beginning of May during the car presentation. Do you want to know more about the team and follow how they built and race the hydrogen car?

FASTTRACK PROJECT

Fasttrack top 20 pitch

In September, Magnetic Innovations submitted an idea to FASTTRACK. Out of all 118 submissions, only 20 were invited to do a pitch at the end of October. We were one of those!

FASTTRACK is a consortium of three family-owned companies. They connect various industries and companies with each other. All this under the motto “Let’s work together, let’s grow together“.

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.

IEC STANDARDS FOR ELECTRIC MOTORS

IEC STANDARDS FOR ELECTRIC MOTORS

IEC STANDARDS

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:

IEC standards 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
