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.

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.

A 16mm encoder from maxon for precise positioning and control of DC motors.
Maxon encoders allow for precise position and velocity control of DC motors. The latest release is a top-of-the-range high-resolution encoder, the ENX 16 RIO (Reflective, Interpolated, Optical). This encoder offers an impressive resolution of up to 65,536 counts per turn in a casing that is robust and compact. The resolution can be configured at the factory, that is particularly useful where the DC motor combination is tailor-made and then resolution can be refined to the respective motor. With 16mm outer diameter and 7mm overall length, the housing is mechanically tough and protected from dust due to its injection-moulded construction. The encoder operates at temperatures ranging between -40 °C to +100 °C.
Requirements on encoders are becoming more and more demanding. This applies particularly to positioning applications with precision constant-speed control, where increasingly compact housings need to accommodate an ever greater number of electrical connections. The encoder can be configured with matching maxon DC motor and gearhead combinations online. It fits the new brushless EC-i 30 motors and the brushed DCX motors (with 16mm diameters plus). The counts per turn and the electrical interface of the encoder can also be configured specifically.

The Shanghai Tower building is the second tallest in the world with a lookout platform 561 metres high. To get to the viewing platform, maxon DC motors will open the lift doors for you.
Three express elevators service the world’s highest lookout platform within the Shanghai Tower. Moving at a speed of 20.5 meters per second the express elevators will bring you to a mesmerising view in less than 30 seconds. A maxon DC motor opens and closes both the doors of the elevator cab and the doors at each individual floor. The DC motors were selected for being small yet powerful, reliable, energy-saving and intelligent.

maxon Brushed and Brushless DC motor control unit software and firmware update.
With the release of the maxon motor EPOS 4 also comes new functionalities across the range of DC motor position controllers. The new EPOS 4 firmware 0120h is available now and offers a range of new features and changes. Now inclusive of the new EPOS 4 50/5, brushless DC (BLDC) motor commutation is possible with absolute SSI encoders eliminating the need for hall sensors. The upgrade also brings the digital input functionalities of drive enable and quick stop, plus watchdog handling with error signalisation. Performance has been improved on the CAN PDO communication and performance monitoring. To compliment the performance upgrades maxon motor have released the new PC configuration software EPOS studio version 3.2. The new position controller software features a command analyser tool and a CANopen wizard. The new EPOS command library 22.214.171.124 including the Windows DLL 64-Bit and 32-Bit, Net Library, LabView Instrument driver and Linux Library now have support of the new firmware features and support of mixed gateway topologies for windows DLL.

maxon motor have unveiled the first sterilisable encoder for brushless DC motors. This will create many opportunities for advances in medical technology.
The first steam sterilisable encoder has been released by maxon motor. The ENX EASY is available in two versions, as an incremental (1024 CPT) and an absolute version (4096 CPT). It can be integrated into suitable motors without increasing the length. The encoder has allowed maxon to create the first sterilisable drive system with brushless DC motor, gearhead and integrated encoder.
Ideal for demanding medical / surgical applications where speed and positioning control tasks are performed. Available with ball bearings or in a ceramic version. The encoder delivers high speeds, extremely precise commutation, low vibration and reduction of heat build-up. To optimise costs and space restrictions, the encoder is integrated in the brushless DC motor.

For applications withstanding tough environments particularly suited to defence, marine, aerospace, scientific research and oil & gas industries.
Excessive humidity, condensation and airborne pollution can cause corrosion, reduce surface resistance, and trigger metal migration. maxon’s new DC servo motor controller is not affected by these conditions, due to the polymer-coated circuit board. Even silicon or lubricant oils do not stick. The controller withstands ambient temperatures from -40 °C to +92 °C. The vibration and shock endurance comply with the high requirements of the Environmental Engineering Considerations & Laboratory Tests (MIL-STD 810F).
This results in a wide range of applications in fields like defence, marine, aerospace, scientific research, oil refineries and automotive systems.
Available to order online from May onwards, the DC motor controller is designed for both brushed and brushless (with Hall sensors) DC motors up to 400 W of continuous power and 750 W of peak power. The Servoamplifier has configurable digital and analogue inputs along with current limits and speed ramp settings.

New levels of torque and position capability are now possible with the development of adaptive hardware for maxon low profile brushless DC motors and harmonic planetary gearheads.
Pictured is a combination showing the maxon brushless DC 70W 24V motor, 2048 counts per turn internally integrated encoder and the new harmonic light weight low profile zero backlash gearhead. The gearmotor assembly increases the torque and reduces the size of previous solutions using planetary gearbox technology. The output capability is 19Nm repeated and 31Nm intermittently, which is ground-breaking for a combination just 55mm diameter and 59mm long for all three components. Having and internal encoder and a zero backlash gear makes the unit ideal for robotic joint and positioning applications in industrial automation, process control and also for precision laboratory and scientific equipment.
