Renewable wind energy harvested from an altitude of 500m.

Clean energy from alt 500m-Kite

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.

New high resolution encoder for DC motors and when to use them.

 

DCX16S_ENX16_RIO_450px

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.

New top of the range compact DC motor encoder

ENX_16_RIO_450px

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.

Mechatronic drive system in elevator doors

elevator

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.
