Brushless motor with encoder and gear. Customised to perfectly match critical servo motor requirements

Requiring up to 22Nm of intermittent torque with only a tiny amount of available space, only maxon motor could custom build the perfect solution for this application. The brushless DC motor contains an internal 1024cpt encoder and is only 22mm long.

Outrunner style pancake motors have an external rotor which offers both advantages and disadvantages. The brushless DC motor has the rotor magnets mounted on the outside of the stator giving the motor more available torque via the additional distance between where the force is produced and the shaft. Essentially, more leverage. However, having an external rotor leaves the rotating mass exposed to the operating environment where it could potentially be impacted upon and create imbalances on the motor.

maxon motor were able to combine a unique combination of a flat brushless DC motor with an internal 1024 count per turn encoder with a ceramic planetary gearhead to meet a customers’ application requirements, though the exposed rotor was a concern for the engineer. By re-designing the front mounting flange of the motor, maxon were able to build a custom rear cover for the motor to protect it and stay within the maximum 43mm available diameter. This must be designed around the thermal requirements of the motor when working in the application environment under the specific loads and duty cycles.

Customisation processes like this for specific requirements then become available for other applications and eventually catalogue components. The motor is now available for system voltages from 12V to 48V with internal encoders from 256 counts per revolution to 2048 counts. There is a ventilated version for high power density, a standard version and an enclosed version.

Brushless DC flat motors – in parts.

maxon motor Australia’s new frameless DC motor and encoder set allows even further miniaturisation and integration. The new motors meet the increasing need for smaller robotic actuation by assembling individual parts directly into the robotic joint.

This is the new frameless brushless DC motor (BLDC) with a diameter of 45mm and an assembled depth of just 23.7mm, it has a continuous rating of 50W. 70W and 130W versions are also available. The frameless design is particularly suitable for processing machine or rotary stage manufacturers who need a large through bore to pass cabling or tubing. For positioning a high resolution magnetic encoder ring also with the same bore as the motor rotor is also supplied as components. The encoder ring is marked with the zero position to allow alignment with the motor zero commutation point in the application and is available in IP rated, absolute and incremental options. The combination gives a low profile large bore positioning system made up from standard parts with shorter lead times than specialty manufactured complete assemblies. The second advantage is for space saving in applications already containing joint actuation bearings or mounting systems there is no need for a second set within the motor.

First maxon motor of its kind. Brushless DC motor with hall sensors, absolute encoder and incremental outputs

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.

Robots for playing soccer through to disaster relief

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.

Saving the lives of preemie babies.

Paul is a robotically simulated training model of a 27 week old preemie baby. Created by an Austrian paediatrician to help train medical practitioners, maxon motors replicate the breathing movements of the baby.

Meet Paul. The smallest and most advanced high-end patient simulator in the world. Paul is a 27 week old preemie. He is 35cm long and weighs 1kg. He breathes on his own with a consistent heartbeat. His chest gently moves up and down, veins and arteries are visible under his thin skin. Paul needs artificial respiration and will sometimes turn blue.

Born to train medical staff in emergency situations that occur every day in neonatal intensive care units, the creator of Paul is Jens-Christian Schwindt, an ex-paediatrician in the Division of Neonatology of the Vienna General Hospital. In 2015 Schwindt started his company SIMCharacters, that arose from a need where “Critical situations in preterm care have to be trained time and time again, under as realistic conditions as possible, to ensure that everything goes equally smoothly in a real crisis” says Schwindt. With the ability to evoke emotions and cry, the baby looks exceptionally lifelike and is full of high-technology on the inside. His skull hosts a Linux system, he is charged cordlessly by induction using a customary charging pad. Paul can be operated for up to two hours. When he has difficulty breathing or the oxygen saturation drops, his head turns blue. Sophisticated hardware and software fit into a silicone skin.

maxon DC motors, gearheads and sensors ensure that the thorax and abdomen move in accordance with the programmed test scenarios. Three DCX 12mm motors with gearhead and sensors are used – two for Paul’s thorax and one for the abdomen. Another maxon DCX 6mm motor moves a valve in the lung of the simulator, with a total of 40 motors installed. The motors were selected for their torque, density and quiet running. The robust design and the ironless maxon rotor make these motors a perfect fit for this unique application. Maxon’s DCX motors are brushed and available in sizes from Ø 6 – 35 mm. They can be easily configured online and customer can select from graphite and precious metal brushes, sintered and ball bearings, and many other components.
