From two to eighty axis – maxon motor release a revised, versatile multi axis motor position system.
Need an eighty axis position control system? Well let’s face it, not everyone does. Though more often than not, in today’s increasingly sophisticated world of motion systems three and four axis systems are required. The trouble for motion control suppliers is being able to meet customer demands for motor position control systems with seemingly infinitely variable requirements.
Three axis controller systems in the past were very common but when you needed to control four motors there were two servoamplifiers paid for but not used. What made this industry standard even more inefficient was that inside the box for these motion controllers was simply three separate motor control units connected on a Bus system. This describes the problem that maxon multi axis system has solved.
Developed as an eleven axis motherboard with snap-apart individual drive segments. The exact number of motor axis can be easily configured simply by separating the required number of drives and jumping both the power and communications along the board. It is an incredibly simple though effective solution that has now been tested and proven in every combination. The most notable application is an eighty axis motor control system for a complex food handling production line.
Technical features include: CANopen control, Interpolation Position Mode, 6 digital inputs and 2 analogue inputs per axis, current regulation and a wide voltage input.

New BLDC design has the advantages of both outrunner and inrunner brushless DC motors.
Outrunner motors offer many advantages, the biggest of them being the maximised distance from the shaft centre to the flux gap of the motor creating a larger lever arm effect from the torque production location to the axis. The larger diameter of outrunner motors therefore gives typically very good torque characteristics. There are also disadvantages of BLDC outrunner motors. The externally rotating rotor and static internal stator is a particular concern in any equipment that is operating near people or in harsh environments. This new design offers an “internal external rotor” that is contained in a aluminium or optional sealed stainless steel motor housing. There are other additional advantages for the new design. The design contains a unique internally mounted 4096cpt incremental encoder and can be assembled with high torque ceramic planetary gearheads, producing a positioning drive system with a slow motion high torque focus. Applications in process control, valve actuation and industrial machinery are particularly suitable for this new motor.

New industrial series IP65 hollow shaft right angle gearmotor.
Featuring high power density this 60mm diameter 400W 48V brushless DC motor and right angle helical bevel gear combination can deliver 25Nm of torque. Loads can be mounted traditionally via keyway or coupling and also through-shaft clamp collar fittings can be used. The brushless DC motor’s rear cable entry housing contains a 5000cpt 3 channel encoder and a DC holding brake for safety critical power failure load holding. Two different 48V windings allow for high speed and low current preferences making control selection easy and cost effective. All surfaces are gasketed, all bearings are rubber sealed and cables are grommeted for industrial operation in harsh environments making the drive particularly suitable for oil and gas, mining and agriculture applications.

maxon DC motors are currently on Mars, helping collect vital information on the Red Planet.
On November 26, 2018 NASA’s InSight rover touched down on Mars. maxon DC motors went straight into action to unfold the two solar panels, securing the energy supply that operates the all-important probe. There are two main instruments onboard InSight, a seismometer to measure potential quakes on Mars and a heat sensor designed to drill down five meters into the ground. The sensor was developed by German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR). Its rod digs into the hard soil using a hammer mechanism, driven by a DCX motor from maxon. The rate of boring down strongly depends on the composition of the soil, which hasn’t been ideal, the rod hit an obstruction in the very first hammering cycle. However, the engineers at DLR are confident these complexities can be overcome and that the sensor will reach the projected depth.
To efficiently drive the penetrometer into the ground, the DC motor needed to withstand forces in excess of 400 g – and more than 100,000 times. It took a number of variations and failed tests to find the right solution. The result is a standard DCX 22 motor, greatly modified with additional welding rings, bearing welds and specially shortened brushes. The GP 22 HD gearhead, on the other hand, only needed Mars-specific lubrication.
InSight’s mission is to carry out several measurements over a period of two years and provide insights into Mars and the formation of Earth. The mission is being conducted by the Jet Propulsion Laboratory (JPL) for NASA.

maxon motor have achieved higher levels of power density for their 4 pole brushless gearmotors.
Up to 96% efficiency and 5Nm from a gearhead that is only 22mm diameter. This new series of ultra-power gearheads has been perfectly matched with a 4 pole 120W brushless DC motor and a 1000cpt 3 channel encoder. With the exception of maxon motors specialist oil filled heavy duty gearboxes the new series gives the highest torque levels available from 22mm. Intermittent torque ratings have increased from 3.8 to 6.5Nm with a maximum speed input of 10,000rpm. The pictured combination is the first of the series supplied to customers in Australia and also exhibits a custom shaft with key and keyway. Additionally, the motor is fitted with temperature sensors in contact with the winding to allow the brushless DC 4 pole motor to be pushed to its continuous thermal capacity. A sealed bearing system and continuous welding of inline components protect the assembly for use in harsh environments and give optimal assembly strength making the gearmotor series particularly suitable for Aerospace applications.

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.

maxon is a Presenting Partner at the second CYBATHLON event in Zurich.
Due to take place on May 2nd and 3rd, 2020, the CYBATHLON is an exciting event run by ETH Zurich where people with physical disabilities compete against each other, overcoming everyday obstacles and showcasing state-of-the-art technical assistance systems. The competition presents new challenges (eg. the wheelchair circuit now includes opening a door with the aid of a robotic arm) and spans six disciplines:
- virtual racing using thought control
- bicycle racing with electrical muscle stimulation (FES)
- dexterity challenges with prosthetic arms
- obstacle course with prosthetic legs
- obstacle course with robotic exoskeletons
- obstacle course for powered wheelchairs.
maxon supported CYBATHLON in 2016 as a Partner. Among other contributions, the trainees of the company built a height-adjustable podium. maxon were keen to join the second event this time as a Presenting Partner. CEO Eugen Elmiger says: “We believe that excellent engineers with a curiosity for new things can make the world a better place. This is why maxon has supported this right from the start.” The company is involved in many of the participating teams, offering support with discounted drives and know-how through its Young Engineers Program. For more information please see https://drive.tech
Nearly all availability across the six disciplines has been taken, with two thirds of the teams coming from universities. The teams are currently in the development and testing stage setting their sights on successfully overcoming the obstacle course in a year’s time. Tickets are available now, for more information please visit www.cybathlon.com.
