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.

With the introduction of the ECX 19 SPEED brushless DC motors, maxon are phasing out the EC 19 and Planetary Gearhead GP 19.
The EC 19 and the GP 19 M were officially introduced in 2014. They will be replaced with brushless DC motors – the ECX SPEED 19 series. Final orders will be received up to December 22, 2017 with last delivery scheduled for March 30, 2018.
The alternative is the brushless ECX range of DC motors. Configurable online, these brushless DC motors are sterilisable, have ceramic bearings and are available with or without hall sensors. With an ironless winding these DC motors have an exceptionally large speed range, high power, excellent control characteristics and are highly durable. Choose from matching gearheads and with the option to configure the electrical connection.
For more information on an alternative DC motor or for application assistance, please call maxon motor Australia on tel. +61 2 9457 7477.
For applications requiring a DC micro motor that is robust, powerful and delivers high performance.
maxon have released two new brushed DC micro motors available in 6mm and 8mm diameter as part of their DCX range. The DC motors have a robust design with maximum power density from the high-performance neodymium magnets.
Also available are matching gearheads, the planetary gearhead 6mm and planetary gearhead 8mm, as well as two motor controllers, the ENX 6/8 OPT (optical) and ENX 6/8 MAG (magnetic). The matching planetary gearheads are welded directly to the motor and offer reduction ratios of up to 1000:1. Both are able to transmit short-term torques of 60 and 150 mNm respectively. The motor encoders are available in two versions for each diameter and work with voltages as low as 3V, therefore making them highly suitable for medical devices. The encoders come in a magnetic version and for magnetically sensitive applications, the optical encoder is available.
These micro motors are configurable online and available for dispatch in 11 working days from date order placed.

The first of its kind! Brushless DC motor (BLDC motor), Planetary Gearhead and a choice of incremental and Absolute encoder all assembled to order in sterilisable form.
This is the first time a sterilisable encoder has been offered and it opens up new possibilities for the medical automation, laboratory automation and dental fields. A full position controllable system that is sterilisable.
The new encoder will have the optional output formats of both incremental to 1024 counts per revolution or Absolute with a 4096cpt (12 Bit). In standard combination with high speed brushless motors in 13mm and 16mm diameter speeds of 120,000rpm are possible and power levels over 100W. The high input speed gearheads can be selected with the correct ratio so match the applications speed and torque requirements and are of a robust stainless steel laser welded construction. Medical hand tools and specialist tools for controlled environments will benefit from this new development.

Getting the balance right with mechatronic systems involves the focus on a whole system and using modular motor system components for successful integration.
The new educational website by maxon motor drive.tech showcases the latest technologies and applications in the advanced motion control world. Dr Urs Kafader’s new article explains the process of getting the balance right in the critical motion control application of modern prosthetics.
Artificial limbs have rapidly moved into the world of advanced mechatronics. The synchronisation of multiple DC motors, sensors, transmissions and processors has become decentralised. The DC motors in these systems are required to fulfil an increasing number of functions that could soon encompass every human (or animal) movement. As such a huge variety of dynamics within the DC motor are required and modularity of components becomes a powerful ally. Each motor in these dynamic multi axis coordinated systems can now be locally controlled with real time field buss communication with full interpolation.

The number of worldwide medical patents filed in 2015 was more than twelve-thousand. The term “innovation” certainly applies to this industry.
In the field of medical technology, surgeon’s tools and machines are becoming smaller. Robotic assistance is commonplace in prostate surgeries. Minimally invasive surgery, surgical tools that can reach sensitive and in-depth parts of the brain once considered too high-risk, are being explored. Machines that aid faster patient recovery times and robots that assist in rehabilitation. Maxon motors are at the forefront of medical technology, working along-side Universities, start-ups and multi-national corporations. Medical applications that have maxon DC motor technology and expertise include the da Vinci Robot, wheelchairs that can climb stairs, aortic pumps for heart patients, implantable dosage systems, robotic exoskeletons, surgical tools and prosthetics.
