The latest issue of maxon’s driven magazine looks at developments and trends in e-mobility.
50 years ago, it wouldn’t have been dreamed of that a family could go on a trip in their car without burning a drop of fuel. Or that inexperienced cyclists could tour vast mountain ranges. Or that robots pull weeds, not humans. These are three, of many, examples that show the influence of electric drive systems on our daily lives and our mobility.
In addition to e-mobility developments, readers get an insight into the battery development at maxon and meet a friendly superhero with a disability. For inquisitive minds, there is an in-depth technical article about inductance in iron-core DC motors.

Global DC motor and drive specialist maxon motor has recorded growth across innovation, markets, revenue and production in 2017.
Sachseln/Obwalden (Switzerland) – The maxon motor group accomplished record revenues in 2017reporting a rise by 8.6% to CHF 459 million (up from CHF 422.5 million in the previous year). All markets contributed to the growth. Cash flow increased to just under CHF 50 million (up from 41.7 million). The number of employees globally increased to 2577. At a 40% revenue share, medical technology continues to be the strongest sector, followed by industrial automation at 28%. With R&D investments of CHF 34 million and more than 360 employees in our R&D sites worldwide, maxon has succeeded in bringing more than 20 new motors and gearheads to market and expand the company’s position as a leading manufacturer of high-quality drive components and systems. maxon looks to the future with confidence.
The impetus of growth behind maxon is mainly from the innovative precision DC motors and drives with high efficiency as well as the matching electronics for controlling complex motion sequences. The company produces in Sachseln/CH, Sexau/GER, Veszprém/HU, Cheonan/South Korea, and soon at its new factory in Taunton near Boston/USA. In addition to the sites above, R&D facilities are also located in China, France, and the Netherlands.
Growth in all markets worldwide
The biggest market in Europe is Germany, followed by Switzerland and the UK. Italy and the Iberian peninsula also grew markedly. After some years of stagnation, a strong growth has also picked up in the US. In Asia, maxon achieved new records in Japan, South Korea and Taiwan. In China, maxon has seen double-digit growth over the past years. “The revenue increase by 100 million over four years has posed a great challenge to us as a company in regard to quality and service. Owing to our highly trained employees, we have been able to master this challenge successfully,” says majority shareholder Karl-Walter Braun.
20 + new products released in 2017 alone
One in seven maxon employees works in research and development. As a result of these steadily expanding capabilities, maxon launched more than 20 new electric motors, gearheads, encoders and controllers in the past year. In aerospace, the motors work at temperatures as low as -130°C, while ESA’s Mercury Planetary Orbiter space probe has to withstand temperatures of more than 350°C on its flight toward the sun. In 2020, high-performance maxon motors will be used in two rover missions by ESA and NASA, after having run for more than 15 years in the hostile Mars environment despite a scheduled service life of only a few weeks.
“Our ‘Mission 2020’ strategy for growth, which we launched years ago with the goal of achieving forward integration of drive systems, is showing some initial success,” says Eugen Elmiger, CEO of maxon motor group. “For example, we’ve been able to secure a large order for pump systems to reduce nitrous gas emissions in Diesel cars in the highly competitive automotive market. We also drove forward the development of complete surgical power tools, as well as micro-pump systems used in minimal invasive cardiac surgery.” Eugen Elmiger also expects healthy growth for the user-friendly and efficient high-performance multi-axis controllers made by zub, a company acquired by maxon last year.
Looking ahead: a strong start
The first months of the new year were characterised by strong growth across the group. Pending orders and revenues exceed the figures of the previous year. Due to the overall economic development, the company expects growth to slow down somewhat in the second half of the year. “We will approach further expansion with the necessary caution,” says Karl-Walter Braun.

Developing Exoskeletons for children present their own engineering challenges simply because children are still growing.
Exoskeletons were largely developed for people that have sustained paralysis or suffer muscular dystrophy. For adults who have stopped growing there is no risk of outgrowing the exoskeleton. However for children their growth and ability present a multitude of challenges for design engineers. An exoskeleton that fits a six-year old perfectly may be much too small by the time the child turns seven. For a child with spinal muscular atrophy an exoskeleton is designed to recognise users are not completely paralysed but are able to move their legs to a certain extent. Sensors within the frame detect weak leg movements and respond immediately to provide support. As a result, the child is able control the exoskeleton directly with the legs.
Spanish company, Marsi Bionics, manufactures exoskeletons mainly for adults but have developed two exoskeletons for children, the Atlas 2020 and Atlas 2030. Weighing approximately 14 kgs it is made for children from 3 years up who have a neuromuscular disease. The exoskeleton can be adapted to various leg lengths and hip widths, so that it also fits teenagers up to about 14 years of age. The “Atlas 2030 is an upgrade of Atlas 2020”, explains Elena García, creator and co-founder of Marsi Bionics. “The main difference is that Atlas 2020 is intended for use in hospitals for gait training and rehabilitation, while Atlas 2030 is designed for use in private homes as an integral part of the patient’s everyday life. Both devices are ready for industrial production and until then, Atlas 2020 will continue to be used in hospitals for clinical research.”
maxon motor have five drive systems in each leg of the children’s exoskeleton. Brushless flat EC45 motors deliver very high torque in a compact design, coupled with inductive MILE encoders that act as sensors. The motors are controlled by servo controllers from maxon’s ESCON series. “EC flat motors provide the best power-to-weight and power-to-volume ratio”, explained Elena García. “This is a variable of paramount importance, as gait exoskeletons require high power but a very low weight and volume.” The exoskeletons will be made available commercially once CE certification marks have been received.

Paul is a robotically simulated training model of a 27 week old preemie baby. Created by an Austrian paediatrician to help train medical practitioners, maxon motors replicate the breathing movements of the baby.
Meet Paul. The smallest and most advanced high-end patient simulator in the world. Paul is a 27 week old preemie. He is 35cm long and weighs 1kg. He breathes on his own with a consistent heartbeat. His chest gently moves up and down, veins and arteries are visible under his thin skin. Paul needs artificial respiration and will sometimes turn blue.
Born to train medical staff in emergency situations that occur every day in neonatal intensive care units, the creator of Paul is Jens-Christian Schwindt, an ex-paediatrician in the Division of Neonatology of the Vienna General Hospital. In 2015 Schwindt started his company SIMCharacters, that arose from a need where “Critical situations in preterm care have to be trained time and time again, under as realistic conditions as possible, to ensure that everything goes equally smoothly in a real crisis” says Schwindt. With the ability to evoke emotions and cry, the baby looks exceptionally lifelike and is full of high-technology on the inside. His skull hosts a Linux system, he is charged cordlessly by induction using a customary charging pad. Paul can be operated for up to two hours. When he has difficulty breathing or the oxygen saturation drops, his head turns blue. Sophisticated hardware and software fit into a silicone skin.
maxon DC motors, gearheads and sensors ensure that the thorax and abdomen move in accordance with the programmed test scenarios. Three DCX 12mm motors with gearhead and sensors are used – two for Paul’s thorax and one for the abdomen. Another maxon DCX 6mm motor moves a valve in the lung of the simulator, with a total of 40 motors installed. The motors were selected for their torque, density and quiet running. The robust design and the ironless maxon rotor make these motors a perfect fit for this unique application. Maxon’s DCX motors are brushed and available in sizes from Ø 6 – 35 mm. They can be easily configured online and customer can select from graphite and precious metal brushes, sintered and ball bearings, and many other components.

A recently patented technology uses maxon DC motors to help people look their best.
endermologie® is a beauty therapy, cell stimulation procedure, created by French company LPG nearly 30 years ago. Initially developed to treat scar tissue and aid in the skin’s healing process, it became apparent that this treatment served twofold. Use of the instrument led to tighter, supple skin, and a reduction in cellulite and fat cells in the hypodermis. Today, approximately 200,000 people in 110 countries undergo treatment with LPG technology every day. Recently LPG launched a new version of this technology announcing the Endermolift method. Organically reactivating skin cells’ processes, this 100% natural, non-invasive, non-aggressive mechanical skin stimulation technique works by applying suction to the skin by the head of the device. Stimulation is brought about by two pulsing flaps, whose beat frequency can be adjusted by the therapist. In the machine is a maxon brushless DC motor and planetary gearhead. The gearhead was customised with the addition of plastic parts to minimise the noise level. The DC motors were selected for their quiet operation, reliability, torque, speed and long service life.

There are many different benchmarks in the marketplace for the sterilisation capabilities of devices. maxon motor explain the cycle and testing process for Autoclavable brushless DC motors.
maxon motor develop brushless DC motors that can be sterilised for medical and dental applications. Recently released is the new ECX range of motors with sterilisation capability on 13,16,19 and 22mm diameter versions. The new range of motors complement the existing 4 pole sterilisable 30mm brushless 150W motor and offer high speed capability up to 120,000rpm. maxon motor test the brushless motors to either 1000 autoclave cycles or 2000 cycles depending on the product. For motors with hall sensors fitted the motor is typically cycled through 1000 autoclave cycles and without hall sensors 2000 cycles. Gearheads are available with additional shaft seals. With the additional seal they are tested to 2000 cycles and without, 1000 cycles. Another new product that offers a completely sterilisable positioning system for the first time is an encoder rated and tested for 1000 cycles.
The maxon motor internal autoclave testing is carried out with the autoclave with a vacuum phase. The motors are unpacked and mounted without any additional protection. Three vacuum cycles are made at the beginning to ensure the internals of the motor become damp. The sterilisation atmosphere is built up with steam which remains constant for 18 minutes at 134˚C, 100% humidity and 2.3 bar of pressure. The unit is then cooled to 70˚C and dried. Each individual autoclave cycles takes approximately 1 hour. After 100 cycles the motors are removed from the autoclave and visually checked and motor operation is checked. Following this the motor is then removed after 250 cycles and visually checked in addition to data acquisition of the running data, motor noise, vibration and electrical strength test at up to 500V DC. Typical batch test cycles are conducted with 10 pcs and the tests are repeated with design changes. Internal testing of the motors to 2000 cycles takes approximately six months.

New brushed DC motor design from maxon motor.
maxon motor Australia have configured a combination of brushed DC motor, planetary gearhead and digital incremental encoder with completely customised features for a prominent medical manufacturer and have produced it in 11 working days.
An interactive 3D model of the entire assembled combination showing all modifications and final production part numbers can now be generated within an hour of specification request along with data sheets showing the working points of the application. The new process eliminates large amounts of traditional internal procedures, with the robotic production line and parts procurement all linked together with the new design tool. The new motor pictured below shows a unique stepped planetary gearhead that uses a 26mm diameter on the high speed input stage and a 32mm on the high torque output stage. Focusing the wear and strength attributes by placing components specific to their role also increases the motors power density. In order to allow for the full use of shaft length that is tailored for the application, a new process of laser welding the inner race of the output bearing directly to the shaft material has been used over the traditional methods of c-clips and shaft collars. This is also naturally stronger than glue and press fit methods. The motor is capable of producing over 10,000rpm and the gearhead up to 12Nm with ratios to 1526:1. Zero cogging and linear characteristics combined with new encoder resolutions up to a staggering 65,536cpt open new position control possibilities for automation, tool and robotics applications.
