Achieving a combination of zero magnetic cogging and zero backlash in a 24V gearmotor assembly.
This new motor and gearhead from maxon motor Australia achieves over 60Nm on a continuous basis at only 10A current draw with a 24V DC supply. New achievements in the 94% efficient motor which features a coreless zero cogging winding (detent free) coupled with a zero backlash gearhead that features high stiffness levels make the drive suitable for robotics and process applications that require completely smooth motion with high power density. Sealed and lubricated for life the combination can handle harsh industrial environments and a -30 +100C ambient temperature range. Gearhead ratio reductions up to 160:1 can also be multiplied by large amounts by stacking planetary input stages and high resolution encoders allowing for accurate positioning tasks. maxon motor Australia now have the ability to configure zero backlash solutions to suit the application requirements.

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.

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.

Maxon motor have supplied DC motor and gearhead combinations for NASA’s fifth Rover mission – the 2020 Mars Rover.
NASA’s Jet Propulsion Laboratory is building a Rover that will travel to Mars in 2020. The purpose of this operation is to collect dozens of soil samples, seal them and leave them on Mars for future pick-up. Nine brushless (flat) pancake DC motors and gearhead combinations from maxon’s standard range – that have been heavily customised to withstand the harsh conditions on Mars – are used in the sample handling arm, specifically developed for this mission.
The sample handling arm moves the containers from station to station within the sampling system. Additional DC motors are also in the Rover and assist with obtaining the samples and sealing the containers. Maxon’s brushless DC motors and gearheads need to survive the powerful entry, descent and landing sequence as well as the harsh daily conditions on Mars with sandstorms and temperatures ranging from -130 to +70ºC.
From the outside, the Mars 2020 rover looks similar to its precursor Curiosity, that is still operating on Mars. The 2020 mission will have several new instruments on board to deliver unique new data. A key objective will be to search Mars for bio-signatures. Another instrument on board will test whether it’s possible to generate oxygen from the atmosphere for possible future human visits. However, the most significant innovation is the ability to take rock samples in several locations and prepare them for return to Earth.

Throughout 2016 maxon invested significantly in expanding its facilities, bringing a large number of new technologies & innovations to market and expanded on their market leading position.
Sachseln/Switzerland – The maxon motor group further increased its revenues in 2016. Compared with the previous year, revenues grew by 5% to a new record level of CHF 422.5 million (from CHF 402.5 million in the previous year). The number of employees rose to 2,500 and for the first time in company history, maxon employs more people abroad than in Switzerland. The highest revenues were achieved in medical technology (43% market share), followed by industrial automation & robotics (26%) and aerospace industries (6.5%). Investment in R&D rose to CHF 28.5 million in 2016 (up from 27.1 million).
Maxon is increasingly becoming a specialist in mechatronics and systems, launching the first fully sterilisable drive system this year. Drive combination units consisting of brushless DC motor, gearhead and sensor are designed to withstand 1000 autoclave cycles. Maxon’s new DC motor controllers also stand up to extreme ambient conditions. The electronics are protected against contaminants and corrosion by a polymer coating. In addition, the device is highly resistant against vibrations and shocks.
For the e-bike market, maxon motor developed a new S-Peledec motor with a 500 Wh battery and intuitive operation for urban applications. The bike reaches speeds of up to 45 km/h and the device stands out because it can convert any regular bicycle into an e-bike. maxon is also active in the field of autonomous delivery robots.

High-tech machines analyse human blood samples and detect coagulation disorders. Maxon motor France supplies the DC drives as well as builds entire conveyor modules especially for a customer.
Analysis devices in laboratories and hospitals run 24/7, autonomously pipetting samples to deliver quick results. Such industrial automation equipment must work with high accuracy and reliability. This in turn places high demands on all components of the machines.
Stago is a French company that specialises in analysis instruments for haemostasis diagnostics (for testing blood clotting). Maxon DC motors are found in Stago’s StarMax machine. A fully automated analysis system, the StarMax is equipped with a three-axes robot with space for 215 samples and 1,000 test containers. Working autonomously the machine checks results, compares them and monitors the processes.
There are several varieties of maxon’s brushed A-max DC motor combined with planetary gearheads, that are used for the movements of the rack. With varying diameters between 16 and 26mm, these DC motors were selected for being highly dynamic and easy to control. The DC motors have an ironless rotor and are manufactured autonomously giving them an attractive price-performance ratio.
