Micro DC motor perfectly adapted

This very small DC micromotor has morphed into a perfect application solution. It is in fact, a brushed DC motor, planetary gearhead and magnetic encoder customised to suit the application.

Being only 10mm diameter it requires close inspection to notice the unique changes that have been made to the motor solution. Through extensive and vigorous testing the design engineers for the end application have individually examined and “tweaked” almost every feature. The first prototypes delivered used a standard maxon RE10 motor and GP10 planetary gearhead. It was found that the extremely space constrained location where the motor is mounted required the assembly technicians to tightly bend the cables where they exited the digital encoder. This caused strain on the solder terminations of the encoder PCB. maxon quickly implemented the customers following request for a resin to be applied at the cable exit to assist with strain relief. This assisted to an extent by making the motor design more robust however it was what is commonly referred to as a “band-aid solution”. Further testing revealed the true cause of the cable strain came about because of an unspecified cable exit angle with relation to the customer fitted custom front flange for the motor. Also further exacerbated by the screw on mounting assembly between the motor and gearhead that allowed for various angle of orientation that were torque dependent. This in a small number of occasions caused the cable to interfere with other components in the machine. A solution offered by maxon motor Australia was that at the point of motor fabrication, the front motor mounting flange and customer drive element be laser welded in place. This is difficult enough to achieve given the motors micro dimensions but additional drastic changes had to be made to facilitate the customisation. This being a completely redesigned gearbox with a stainless steel construction to enable welding of the flange to the motor body. A special jig was constructed to hold the motor and encoder cable exit in specific orientation with the front flange whilst welding takes place to ensure consistent part relationship. Thus, over time maxon motor have morphed a standard catalogue motor and gearhead into a perfectly suited custom solution.

2017: a year of record growth for the maxon motor group

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.

Saving the lives of preemie babies.

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.
