A new method of garnering renewable energy is being explored and it’s not from wind turbines.
A Dutch start-up company, KitePower is creating a system to produce green energy from Kites. In collaboration with the Delft University in the Netherlands, the approach consists of a generator on the ground that is connected directly to a cable winch that has a steered kite attached. The kite pulls the cable upward by flying in a figure-8 pattern creating a strong tractive force with the ability to reach heights up to 500 metres. When altitude is achieved the cable is retracted (using very little energy) and the procedure is repeated.
The device offers an attractive alternative to diesel generators and wind turbines. In comparison the kite needs less material for construction, is more mobile and can flexibly use winds up to 500m. Of particular benefit to secluded communities, military camps or remote islands the first commercial version is due for release at the end of 2018.
Maxon motor is one of a few companies assisting KitePower. Maxon’s expertise is in developing the control unit for the steering movement of the kite. This included integrating DC motors, different sensors, transmitters, receivers and batteries while considering extreme radial forces on the gearhead. The device uses maxon’s Ec-i 52 DC motor with planetary gearhead and encoder. This combination is usually found in robotics applications for its high torque and compact design.

First earth, then outer space and now underwater. The new Aquatic division at maxon motor develop DC motor actuators, thrusters and systems for subsea use.
Focused on applications that require reliability and efficiency the new maxon subsea motors use BLDC (brushless DC motors) in pressure compensated oil filled housings. ROV and AUV applications will benefit from maxon motors’ lighter and more powerful new solutions including four new thruster sizes. The MT20, MT30, MT40 and MT70 can be used at depths to 6000 meters with their corresponding maxon pressure compensators. The maxon thrusters for AUV and ROV applications also have the ability to have the propeller geometry optimised for special requirements, or to use the standard propeller geometry that is most efficient in one direction and has approximately 80% in reverse thrust. External componentry of the thrusters are made from titanium or plastic for use in salt water and all parts have been isolated to prevent galvanic reactions.
A dedicated subsea area with data sheets, application solutions and stories from the field can be found by searching for aquaticsolutions.maxonmotor.com or contact maxon motor Australia on +61 2 9457 7477.

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.

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.
