New DC motor technology released from maxon.

maxon motor is introducing new miniature brushless DC motors, brushless frameless motors in kit form and EtherCAT positioning controller solutions.

A number of new products are released from DC motor drive specialist maxon motor. More configurable brushless DC motors (from the ECX SPEED range) in both Standard and High Power options are available with diameters of 13mm and 19mm, along with matching planetary gearheads and encoders. This brushless DC motor has very high speeds and is particularly suitable for power tools and demanding speed & positioning control tasks. All components can be configured online. These customised drives are assembled using automated processes and are ready for shipping after no more than 11 working days.

Newly released is the popular high-torque powerful brushless flat DC motor available in a frameless kit. This means that the stator and rotor are delivered separately and joined only during the assembly of the device. This brushless frameless kit is especially suitable for robotics applications where space is constrained.

Maxon have also developed their compact EPOS4 positioning controller to be equipped with an EtherCAT expansion board for integration into any EtherCAT network.

These innovations are on display from November 28 to 30 at the SPS IPC Drives exhibition in Nuremberg, Germany.

New high resolution encoder for DC motors and when to use them

maxon motor release its new ENX 16mm RIO encoder with 65,536 counts per turn for DC motor applications requiring fine positioning and constant velocity.

This new encoder has been released with 262,144 quad counts per revolution. But where to use resolutions not seen in such a tiny size encoder? An example would be pick and place machines for the placement of electronic components during pcb manufacture. New microprocessors and FPGA devices can have up to 2601 contact points on a 0.4mm grid. The pick and place machine for this part would need a controllability of nine hundredths of a revolution and the accuracy would require an encoder to be fitted to the positioning motor with ten times this amount. Also applications with demanding constant velocity requirements require high resolution encoders. Enabled by continuously increasing processing speeds new high resolution encoders vastly improve the feedback loop. Each example requires the high resolution and also error free signals at high speeds. The RIO is an Reflective Interpolated Optical design that allows cor compact dimensions of 16mm diameter and 7mm length. Output signals are RS422 differential including an index pulse. Delta robots, Precision manufacturing tools, 3D printers and the semiconductor industry can all benefit from this new product.

Technical report on energy efficiency in small DC motors

The maxon academy have released a new two part technical report into the energy efficiency of small DC motors, micro drives and subsystems.

The maxon motor academy headed by Dr Urs Kafader provides acclaimed technical reports, educational textbooks and technical training on all aspects of DC motor drive systems and associated control devices. The latest technical document authored by maxon motor technical trainer Jan Braun focuses on energy efficiency and highlights how motor efficiency requirements have affected the design of many products. Application examples and selection processes are given throughout. Topics include motors operating in the no-load range, motors operated at standstill, control, load mechanics, pulse width modulation and motor chokes. In an increasingly battery powered and greener world high efficiency design and the correct selection of components are becoming more and more important. maxon motor strives to further educate not only its own engineers but also the designers of the future.

New IP67 12V and 24V DC motors with internal encoder and holding brake.

Supplied via maxon motor Australia, specifically designed for the Agriculture industry is the first of the new IP67 12V and 24V DC motors with an incremental encoder built inside the motor body.

The first motor in this series being developed is the 80mm diameter 172mm long 250W brushed permanent magnet motor assembled with 81mm IP67 gearheads. The IP67 gearhead range has an large reduction range to select from facilitating torque production of up to 180Nm. The internal magnetic encoder sits behind the motor commutator, has two channels and can be run on either 5V DC or 24V DC. Mounting the encoder internally also has the advantage of freeing up the motor rear shaft where an external holding brake can be fitted. The first units supplied will have a B56 brake that combined with gearing can provide the 180Nm of torque also for holding the load in place on the unpowered condition. Future versions will have the option of either power activated or power de-activated holding brakes also with a sealed enclosure for harsh environments.

New top of the range compact DC motor encoder

A 16mm encoder from maxon for precise positioning and control of DC motors.

Maxon encoders allow for precise position and velocity control of DC motors. The latest release is a top-of-the-range high-resolution encoder, the ENX 16 RIO (Reflective, Interpolated, Optical). This encoder offers an impressive resolution of up to 65,536 counts per turn in a casing that is robust and compact. The resolution can be configured at the factory, that is particularly useful where the DC motor combination is tailor-made and then resolution can be refined to the respective motor. With 16mm outer diameter and 7mm overall length, the housing is mechanically tough and protected from dust due to its injection-moulded construction. The encoder operates at temperatures ranging between -40 °C to +100 °C.

Requirements on encoders are becoming more and more demanding. This applies particularly to positioning applications with precision constant-speed control, where increasingly compact housings need to accommodate an ever greater number of electrical connections. The encoder can be configured with matching maxon DC motor and gearhead combinations online. It fits the new brushless EC-i 30 motors and the brushed DCX motors (with 16mm diameters plus). The counts per turn and the electrical interface of the encoder can also be configured specifically.

Exoskeleton joint actuator

maxon motor have developed the Exoskeleton Drive GEN.1 for use in hip and knee exoskeletons.

The global Exoskeleton market is growing in both market share and technological developments at a rapid rate each year. Maxon motor have several global customers we have worked with to develop brushless DC motor solutions for use in robotic limbs.

Available from the beginning of October 2017 is a complete joint actuation unit consisting of a pancake brushless DC motor (EC90 flat) with inertia optimised rotor, Internal high resolution 4096 MILE Encoder, planetary gearhead with absolute encoder and EPOS4 position controller with CAN and RS232 interface. Fitting the 17bit SSI absolute encoder directly at the joint rotation to a degree will negate the effect of gearhead backlash giving designers increased positioning accuracy. The unit will deliver 54Nm of continuous torque and 120Nm on a 20% duty cycle. The system can be operated on supplies between 10 and 50V DC and the actuation speed is up to 22rpm. Drawings and pricing are now available contact maxon motor Australia for further information.

A DC motor kit supplied in parts for robotic joint applications.

Maxon’s brushless frameless DC motors are designed for applications with space and weight constraints.

DC motors don’t always fit seamlessly into applications. Particularly in robotic joints, the space and weight constraints can take off the shelf DC motors past their threshold. These motors must also offer high torque yet be lightweight to meet the needs of the application’s dynamic movements. For this growing market, maxon motor developed a brushless flat motor as a frameless kit. The rotor and stator are provided separately, without bearings and motor shaft and connected when these components are put together. This offering brings the best of both worlds: high torque density with the smallest dimension possible. With outer diameters of only 43 to 90 mm, the brushless frameless flat motors are particularly compact. Designed as external rotor motors, they offer plenty of space inside for cable glands. For easy control these are delivered with Hall sensors.

The benefit of the brushless frameless motor kits are low cogging torque, high overload capacity, high torques through the multi-pole external rotor, space for cable glands, supplied equipped with Hall sensors and thermal sensors, and speaking from our own experience; higher levels of integration into robotic joint applications.

Roboy 2.0

A complete relaunch of the tendon controlled soft Robot, Roboy, is planned for 2018.

Reported here in 2013, Roboy was the first-of-its-kind Humanoid Robot developed by the University of Zurich. What set Roboy apart was the tendon-operated “soft” robotic features. As a main project partner, maxon motor supplied 48 brushless DC motors, gearheads and controllers that enable Roboy to move in a precise manner. Roboy now lives permanently at the Technical University in Munich where development is focused on enhancing A I. This is where the concept of Roboy 2.0 was born, utilising Roboy as a foundation to create robots that not only move like people but will think like people. At this stage Roboy is unable to stand or walk. Roboy 2.0 will be a complete relaunch and the new version will be able to stand, thanks to development of the legs and components like software, DC motors and technology, it is hoped that by 2018 Roboy 2.0 will stand on his own two feet and interact with us.
