More rovers on Mars

In 2020 the European Space Agency (ESA) and NASA will send their rovers to Mars. Here’s a comparison of the two machines.

Both rovers are being deployed to Mars in June/July 2020 to looks for signs of life and take soil samples.

Maxon DC motors feature in both the rovers and here we take a look at the difference between the two rovers.

NASA Mars 2020

Mission start: June/July 2020 aboard Rocket Atlas V-541.

There are nine maxon DC brushless motor and drive systems that help collect the soil samples. The EC 32 flat and EC 20 flat motors fitted with planetary gearhead and customised in commission with NASA/ JPL.

ESA ExoMars

Mission start: June/July 2020 aboard Rocket Proton.

More than 50 actuators from maxon assist with the wheel drive, sample distribution and camera movements. There are 17 different configurations of brushed and brushless DC motors including the DCX 10, DCX 22 and EC 40 combined with gearheads, brakes and encoders.

Autonomous delivery vehicles …..coming soon!

Swiss start-up company TeleRetail is testing a prototype delivery robot that delivers groceries/ small packages autonomously.

Called “mobile trunks” these autonomous delivery robots are small containers on wheels equipped with sensors, intelligent software and powerful maxon DC motors. Made and designed to travel autonomously, reliably and without obstructing or endangering anyone, these small robots reduce congestion on the roads and are more economic to run than an electric car.

Maxon brushless DC motors, the EC 90 flat, features in the mobile trunks. Developed in conjunction with maxon engineers since 2016 the vehicle is still in it’s infancy. Before these delivery robots can be produced en-masse, laws need to change. Currently these types of delivery robots can only move around with the use of special permits away from the large bustling cities.

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.

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.

For more information on any of the above new products please contact maxon motor Australia tel. +61 2 9457 7477.

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. Contact maxon motor Australia for a full copy of the technical report and other resources that are available from the maxon academy. Ph: +61 2 9457 7477.

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.
