Brushless DC motor – pushing it to the limit

maxonmotoraust - Vie, 08/11/2017 - 08:45

When prototyping for applications with extreme requirements for brushless DC motors, fast condition monitoring is critical.

Motor applications with limited space available and comparatively large power requirements can push a motor very close to burning out. In theory, it is possible to use temperature calculations for the motor winding with the help of thermal resistance rating from the motor data sheets, ambient temperatures, heat sinking details and housing characteristics. This is always considered first and then tolerances and safety margins are considered. Following this thermal modelling software and imaging can be evaluated. However some applications push a motor so close to the edge, that only real product prototype testing can be relied upon. Simply installing motors and testing how hard you can push them can also be a costly exercise and does not give enough reliable data. Actual winding temperature sensing on the motor is a solution maxon motor offer for these extreme cases. By inserting sensors through ports in the magnetic return stack and in direct contact with the winding, maxon motor can give customers a device that monitors winding temperatures without the thermal time constant delays experienced when measuring winding resistance and using housing thermal time constants.

Exploring hidden depths under the seabed.

maxonmotoraust - Vie, 07/21/2017 - 07:31

Norwegian company Petro-Marker, developed a device that is able to collect data up to 5,000 meters underneath the seabed. The technology scans the bottom of the ocean in great detail providing information as to the location and size of oil reservoirs.

1,000 metres below the sea the environment is harsh, ice cold and very dark with no natural light. An ROV has strong floodlights that identify tri-pod objects anchored to the bottom of the seabed. These are receiver stations for electromagnetic waves transmitted into the seafloor, giving feedback on the seabed itself and finding resource deposits.

When oil companies want to find out whether drilling at depth is worth the cost, they often rely on Controlled Source Electro Magnetic (CSEM) technology. This technology utilises the differences in the electrical resistance of different bottom layers to provide signs of the location and size of oil fields. The CSEM technology uses a very strong power source to generate an electro-magnetic field, as well as several receivers to record the fields. These tripod receivers are placed on the sandy bottom and pick up electromagnetic signals that have been changed by the layers through which they passed.

In 2016 Petro-Marker placed 25 new tripods in the North Sea. What sets this technology apart is a new measuring method that uses a vertical transmitter and receiver to find resources. This enables a much more detailed resolution and data measurement up to 5,000 meters beneath the seafloor.

The tripods are about 4 meters high and made from a combination of glass fibre and special foams. Due to the sensitive electronics, metal parts cannot be used. This far below the surface, the pressure is extreme, and the salt water is hostile. At the center of the tripods (receivers), the antennas are aligned as vertically as possible on the seabed.

The system uses a maxon controller (EPOS) and a compensator. The units are encased in plastic to protect them from salt-water corrosion. Several modifications were required to meet the requirements of this application: An EC-i 40 motor, GP 42 planetary gearhead and compensator that were all customised. A dual seal, that imitates typical submarine technology, ensures the system is able to resist the enormous water pressure. The control electronics of the underwater drive are housed in a pressure-neutral glass ball that is able to resist the pressures of up to 600 bar – one of the challenges of this extreme application.

Roboy 2.0

maxonmotoraust - Lun, 07/17/2017 - 07:20

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.

Play foosball against a robot!

maxonmotoraust - Vie, 07/07/2017 - 08:34

A robot operates the opposing player rods on a Foosball table and has won against human players.

The Swiss Federal Institute of Technology (EPFL) has developed a foosball table with autonomously operated robotic rods. The table has a transparent playing surface with a camera that locates the ball by taking up to 300 images per second. These images are immediately evaluated and sent to control the rods, which are powered by maxon EC-4 pole DC brushless motors with gearheads and motor controllers. The rods stop the ball and aim for the goals. The students aim to make the robot even more intelligent by programming the robot to analyse opponents players, find gaps in the defence and predict the ball’s trajectory.

Custom DC motor for maximum power density

maxonmotoraust - Vie, 07/07/2017 - 03:24

New brushed DC motor design from maxon motor.

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.

Mechatronic drive system in elevator doors

maxonmotoraust - Mar, 06/06/2017 - 08:39

Maxon brushless DC motors and encoders drive lift doors open and closed.

Schindler is a well-known manufacturer of elevators and lifts, moving more than one billion people every day. When we take the lift, we press the button, the cab arrives, we enter and disembark at the desired floor. What is a simple event has alot of technology in the undertaking – in the elevator shaft, motor chamber, control box and in the lift compartment itself.

A motor installed in the cab opens and closes both the doors of the cab and the doors at each particular floor. The requirements of the motor are very specific: small yet powerful, reliable, energy-saving and intelligent. Maxon developed two Door Drives alongside Schindler, using a brushless DC motor with a diameter of 90 millimeters, a MILE encoder combined with the motor and a customised EPOS2 positioning controller. With two power levels, the more powerful version uses a belt drive and is able to move doors weighing up to 400 kilograms. The smaller and latest version is more compact and moves doors weighing up to 120 kilograms.

Encased in a housing, the Door Drive can be mounted directly onto the lift cab. And this is where its real work starts. The ability to adapt to the many different types of elevators, with differently sized cabs, different materials and, depending on the country, different safety standards. After a calibration procedure, the controller of the Door Drive detects the size and weight of the doors, autonomously calculates the optimal parameters corrects them if necessary and drives the doors open and closed.

For more information on applications where DC motor technology needs to be powerful, compact, reliable and intelligent please contact maxon motor Australia on tel. 61 2 9457 7477.
