Maxon Motors Will Help Travel To The Sun?
On July 20th 1969, The United States Apollo 11 was the first manned mission to land on the Moon. There have been six manned U.S. landings between 1969 and 1972 and numerous unmanned landings, with no soft landings happening from 1976 until 2013.
With the distance to the moon being about 239,000 miles and temperatures reaching from 253°F to -243°F, the accessibility of the Moon is extremely difficult.
It is almost unthinkable traveling to the Sun.
In 2018, the European Space Agency (ESA) with NASA will send its Solar Orbiter into space, equipped with a thick heat shield, in an attempt to understand the secrets of solar eruptions and to understand more about a planet that is responsible for the development of the planets in our solar system, the weather, and life in general.
During its travels, the Orbiter will change its trajectory and swing by Earth and Venus to reduce its distance from the Sun to only 28 million miles. The total distance of the Sun from Earth is roughly 93 million miles. The Orbiter will have travelled almost 70% of the distance to the Sun reaching temperatures of up to 520°C (968°F) and reaching levels of radiation 13X that on Earth. No other human-made object has ever been this close.
Maxon Motors Putting On The Sunglasses.
Now with as much heat and radiation that will be exposed to all of the instruments on-board you might be wondering how are they being protected? A state-of-the-art heat shield will be the “sunglasses” for the Orbiter. The shield itself is made out of permanent beryllium protective filters with the use of an aluminum grid.
Two Maxon RE13 motors will power these state-of-the-art “sunglasses”. These brushed DC motors are wired in parallel enabling them to be used together or individually, which ensures a service life of ten years. Also weight is a very critical factor in space projects.
"The Shield" "Inner-workings of Motor"
Senior Project Manager added “With Maxon motors we were able to build a shield that weighs less than 200 grams and survives vibrations without problems.”…. You can say these are some pretty tough and demanding motors.
If you are ever wondering what motors you should use for your application, just remember Maxon helped take the Orbiter to the Sun.
