For fine motor position control across multiple generation brushless motor controller models, maxon motor Australia has supplied the first of its kind maxon EC-max brushless DC motor with three modes of feedback.
The new micromotor encoder 16 Easy Absolute 16mm x 9mm offers high resolution motor feedback from a tiny package. Additionally it offers 4,096 counts per turn incremental outputs with line driver channels and an index pulse. The Absolute output is available in the choice of Binary BiSS-C or Gray Symmetric SSI. The encoders use an interpolated hall sensor angle measurement system to generate the incremental quadrature output signals according to EIA-422 with 20mA maximum current draw and ESD protections built in. The angle value zero of the encoder is factory aligned with the BLDC motor zero point and the encoder is welded in place on the rear flange of the motor. When fitted with a multi pole brushless DC motor the encoder can still show the angle values zero once per mechanical turn and the angle zero is identical to the index position. The motor itself also contains three hall sensors for commutation purposes. An adaptor is available to convert the single ended clock and data signals of the absolute encoder into TIA/EIA RS422 compliant differential clock and data lines.

This small brushless DC motor displays the advanced miniature and micro motor manufacturing techniques of maxon motor. So small are the details it is hard to capture the modifications and quality. The example pictured is a 10mm diameter DC motor and planetary gearbox fitted with an encoder for speed and position control.
What’s new? Sure there are a lot of small DC motors available now days however it’s in the detail that defines the difference between motors. Pictured is maxon motors newest planetary gearhead range that has been selected because of its stainless steel construction. The body and flange of the gearbox are one piece allowing the design engineers to not only create a mounting flange specific to the mounting footprint available in the application, it also allows maxon motor to orientate the gearhead flange with the motor cable exit. Enabling a shorter cable and neater cable looms. Laser welding of the motor flange is also a technology that is used to affix a customer specific drive pinion to the shaft. This gives the strongest possible power transmission coupling in these miniature sizes. maxon motor provide its customers with complete drawings and models for appraisal before samples are manufactured even for non-standard DC motor and gearhead assemblies like the shown example.
The new 10mm gearhead can supply torque levels up to 200mNm and can operate with input speeds up to 15,000rpm. Standard supply is with stainless steel ball bearings, it has efficiencies as high as 90% and weight as low as 6.7g.

There are additional connectivity options with maxon’s positioning controller, the EPOS4.
The addition of an expansion board now allows maxon positioning controller, the EPOS4, to be integrated into any EtherCAT network as a slave using the CoE standard (CAN application layer over EtherCAT). The EtherCAT card developed for this use can be combined with the EPOS4 controllers in a housing, as well as with all EPOS4 modules. The benefits widen the applications where compact positioning controllers are needed, for example where short cycle times are important in synchronized multi-axis systems.
EPOS4 controllers are suitable for controlling both brushed and brushless DC motors. They are known for their high power density and excellent value for money. For more information about maxon’s EPOS controllers, please visit epos.maxonmotor.com or tel. +61 2 9457 7477.
Brushless DC (BLDC) servomotor, zero backlash gearhead, holding brake and high resolution encoder combination drive offers high torque levels without compromising positioning accuracy.
This servo motor and gearhead combination recently released by maxon motor Australia can produce 364Nm with a peak torque rating at the output of 686Nm. Fitted with both an encoder and a holding brake inside the IP rated motor’s rear enclosure the combination can move heavy loads into position and make sure they stay there. The high acceleration of the brushless DC motor with top grade Neodymium magnets enables a zero to 2600rpm speed change in under 4ms. Being both brushless DC and also slotless gives the motor zero cogging or position detent for smooth position transitions and low speed performance. The solid construction and sealed nature of the motor drive components makes it suitable for mining, food, process control and manufacturing environments. Customisation of the motor and gearhead features is possible and both 24 and 48V DC supplies can be used. The unit is compatible with standard Servoamplifier and position controllers from maxon motor.

At the international RoboCup, maxon motors featured in robots playing soccer and in mock recovery operations.
At the end of July 2017, more than 3,000 participants from 42 countries participated in the annual RoboCup competition held in Nagoya, Japan.
maxon had inbuilt motors and controllers in a rescue robot developed by the Carinthia University of Applied Sciences that placed seventh out of 20 competitors. Scoring high marks for the light design and system approach, the robot contained several DC motor, gearbox and encoder combinations. Using the EC-4 pole brushless motor with 200W power as a base, the motor operated the chains propelling the robot forward. The camera arm of the robot also contained eight maxon DEC 50/5 modules on circuit boards and four 70/10 ESCON controllers for the gripper arm. The machines acted in a simulated disaster scenario carrying out rescue operations and were evaluated based on their performance.
At the other end of the contest was the Soccer finale, with the two competing robots both containing maxon drives. The University of Bonn developed an 18kg, 135 cm robot supported by an exoskeleton that was 3D printed called “NimbRo”. Maxon DC motors were integrated into an actuator drive system developed by a South Korean company. The competitor’s robot, named “Sweaty” and developed by Offenburg University, contained 24 maxon DC motors and gearheads. 18 of these drives were fitted with an overload motor controller and a further two were fitted with an evaporative cooling system to prevent overheating. This cooling system is similar to the way humans sweat hence the name “Sweaty”. NimbRo won 11-1.
