  • NASA is again working with maxon motor.

    Two years from now, the US space agency NASA will send a new rover to the Red Planet. Included: a small helicopter, which will take the first aerial photos of Mars. The rotors will be controlled by robust DC motors from Switzerland.

    The US space agency NASA has announced that their Jet Propulsion Laboratory (JPL) will be sending a helicopter to the Red Planet on the upcoming Mars 2020 rover mission. It will land on Mars whilst attached to the bottom of the rover in February 2021. During the first 30 days of the mission it will undertake several autonomous flights, each lasting up to 90 seconds. We will receive inflight images of Mars back on Earth for the first time! The Mars helicopter technology will lay the way for many future scientific and exploratory missions to Mars. Similar robots could serve as flying eyes for future rovers, exploring the surroundings and finding the best route for the rover.

    Energy-efficient components for extreme conditions

    For the small helicopter to fly, it takes an enormous engineering effort. The thin air on Mars is comparable to the conditions prevailing on Earth at an altitude of 30 kilometers. Even accounting for the reduced Martian gravity, the helicopter must therefore be particularly light (1.8 kilograms) and can only carry small batteries. This requires that the components used are extremely energy-efficient, a requirement that also applies to maxon’s DC motors. The drives from Switzerland have proven themselves in many previous Mars missions and will also be used in JPL’s helicopter. Six DCX precision micro motors with a diameter of 10 millimeters are responsible for moving the swashplate and hence adjusting the inclination of the rotor blades - i.e. for controlling the vehicle.

    The helicopter propulsion system is designed and built by AeroVironment under contract from JPL. maxon engineers have been working closely with the specialists at AeroVironment who are world experts in building micro air vehicles. After a year of development work, NASA’s approval for the inclusion of the helicopter project in the Mars2020 mission is an additional motivation for the Swiss drive specialists. "Being part of another Mars pioneering project makes us incredibly proud and happy," says Eugen Elmiger, CEO of maxon motor.

    Temperature measurement of Mars with the help of a DC motor

    The Mars helicopter adds to several other Mars projects that maxon is currently involved in: For example, in the European Space Agency’s ExoMars rover - with more than 50 drives located in the wheels, drill head, analysis unit and camera mast. This mission is also scheduled for launch in 2020. Significantly earlier, arriving 26th November 2018, NASA's InSight lander will study the Red Planet's seismic activity and planet core temperature. A powerful and robust DC motor from maxon drives a pile driver type mechanism that will burrow almost five meters deep into the Martian soil.

  • The 15-year-old Mars rover Opportunity is fighting another sandstorm.

    On July 7, 2003, the NASA twin robot Opportunity embarked on its journey to the Red Planet from Cape Canaveral, Florida. Today, 15 years later, it is still sending life signs back to Earth – despite a heavy sand storm.

    Over the past few weeks, NASA engineers tried to contact Opportunity several times. However, they haven't heard back from the rover, which is almost 15 years old. The team is now assuming that the charge in Opportunity's batteries has fallen to below 24 V, causing the rover to go into the low-power default mode. In this mode, all subsystems except a mission clock are turned off. The mission clock of the rover is programmed to wake up the computer so that it can check the power.

    If the rover's computer finds that the batteries are not sufficiently charged, it goes back into standby mode. Due to the high amount of dust in Perseverance Valley, the mission engineers believe that it is unlikely for the rover to collect enough sunlight to recharge for the next few days.

    “maxon motors can handle this”

    “Opportunity has braved many minor and major sand storms over the years and has always managed to recover its energy. We have no doubt that our motors will also run without trouble afterwards,” says maxon CEO Eugen Elmiger.

    Opportunity's six wheels are driven by maxon DC motors. The Obwalden-based drive specialist supplied 35 units with diameters of 20 and 25 millimeters for the rover. The maxon motors in the wheels, for example, did more than 78 million revolutions each, under extreme environmental conditions and temperature fluctuations from -120 to +25 degrees Celsius. The experiences from this successful project are being used for the development of new motors that will soon fly to Mars on the upcoming Mars missions by NASA and ESA – to join the next scientific race.

  • maxon motor's EC22HD heavy duty motor; a 22mm-diameter brushless motor that outperforms any other commercial electric drive on shock, vibration and temperature tolerances. This motor was developed for the exceptionally high requirements in deep drilling technology and resists the most extreme operating conditions. Also available in combination with the GP22 heavy duty gearhead in 1 to 5 stages for use in oil or air operation.

    As part of the motor’s development program, a high-temperature test facility was built, and extensive field trials were undertaken. The motor operated at temperatures up to 240°C and under atmospheric pressure conditions from high vacuum to 25,000 psi. It has also been proven to resist impulse and impact forces of 100G. It can operate while submerged in oil, trebling its 80W output rating to 240W because of the improved heat dissipation.

    Although developed to perform critical downhole actuation functions, maxon believes the new motor will also appeal to other industries where reliability is essential. The motor’s efficiency of 88% in air (and above 70% in oil) makes it particularly suitable for battery-powered applications.

  • The Heavy Duty Motor EC 22 HD, has been joined by a larger and more powerful version. The electronically commutated EC-4pole 32 HD motor has all the features of the award-winning 22 mm motor. It is designed for extremely rough operating conditions, particularly applications in deep drilling.

    Deep drilling technology (called “downhole drilling” in the field of oil and gas exploration) makes it possible to recover oil and gas from depths of more than 2500 m. By combining deep drilling with directional drilling (dynamic position alignment of a bore in the earth), previously unreachable oil reserves are being opened up, with drilling depths of approx. 5000 m and drill lengths of up to 11000 m. The development of specialized electronics and drives has made it possible to better monitor and control many functions across the entire drilling process. For instance, it is now possible to dynamically measure and adjust the position of the drill head during the drilling process. Diverse deep drilling tools also use hydraulic valves or flaps that are operated by electromechanical drives. The temperatures and pressures at these depths, combined with the strong vibrations that occur during the drilling work, present unique challenges for the use of electronic drives.

    The different versions of the EC-4pole 32 HD are designed for operation in air or in oil (flooded in hydraulic oil). The power rating depends on the surrounding medium and amounts to 220 W in air and, due to the much higher heat flow, 480 W in oil. They are designed for ambient temperatures of more than 200 °C and atmospheric pressures of up to 1700 bar. The Ø 32 mm motors must also be able to withstand vibrations of up to 25 grms as well as impacts of up to 1000 G (1000 times the acceleration due to gravity at the earth's surface). As an example, a Formula 1 vehicle is exposed to approximately 2 G and fighter jets are exposed to approximately 13 G. The motors feature high efficiency (up to 89% in air, more than 80% in oil), making them ideal for use in battery-operated applications. With their detent-free running properties, they have excellent control characteristics and are suitable for high-precision positioning tasks in outer space, even at low speeds.

    The EC-4pole 32 HD is ideal for use in environments with extreme temperatures, subject to high vibration, or under ultra-high vacuum. This means the motors can also be used in aerospace applications, e.g. for gas turbine starters, for the generators of jet engines, for regulating combustion engines, or for exploration robots. For the use of the motor in conjunction with a gearhead, maxon offers the GP 32 HD, a powerful and robust planetary gearhead.

  • A rugged, compact powerhouse: The ESCON Module 50/8 HE servo controller from maxon motor controls DC motors up to 750 W, even in the harshest ambient conditions.

    The Swiss drive specialist maxon motor is expanding its range of servo controllers by adding the ESCON Module 50/8 HE (Harsh Environment). This compact plug-in module with a nominal current of 8 A is a true powerhouse, designed for brushed and brushless DC motors with a peak power of up to 750 W.

    However, the controller's true strength is its resilience: It performs reliably at ambient temperatures from -40 to +92°C. The electronics are protected against contaminants and corrosion by a polymer coating. Even silicones and lubricant oils do not stick. In addition, the device is highly resistant against vibrations and shocks.

    Heat sink is available as an option

    The new ESCON Module 50/8 HE perfectly complements maxon's existing range of ESCON controllers. It has numerous configurable digital inputs and outputs and is easy and intuitive to set up using the ESCON Studio software. The module is available in two versions, with and without a heat sink.
