Ergoswiss table lifting systems from AutomationDirect

Automation-Direct has added the new SQ series table lifting systems from Ergoswiss. These lifting systems use electrically driven columns that allow the operator to reposition the height of a worktable, conveyor, etc. to meet specific requirements. In doing so, the operator can perform their tasks in a more comfortable working posture, helping to reduce work-related injuries. These systems are all electric (no hydraulic mess or manual hand cranks), and each lifting column features a housed motor and screw drive to perform the needed height adjustments.

Optical rotary encoders: Close the stepper motor linear actuator feedback loop

With the help of a motion controller and a stepper driver, all stepper motor linear actuators can be programmed to position a load to a precise location. However, standard configurations do not provide a feedback mechanism that tells the operator whether the move is completed or not. Adding an encoder can be an effective and simple solution to get real-time motion feedback about your application.

Vertical turbines could be the future for wind farms

The now-familiar sight of traditional propeller wind turbines could be replaced in the future with wind farms containing more compact and efficient vertical turbines. New research from Oxford Brookes University in the UK has found that the vertical turbine design is far more efficient than traditional turbines in large-scale wind farms, and, when set in pairs, the vertical turbines increase each other's performance by up to 15%.

A research team from the School of Engineering, Computing and Mathematics (ECM) at Oxford Brookes led by Professor Iakovos Tzanakis conducted an in-depth study using more than 11,500 hours of computer simulation to show that wind farms can perform more efficiently by substituting the traditional propeller-type Horizontal Axis Wind Turbines (HAWTs) for compact Vertical Axis Wind Turbines (VAWTs).

VAWTs spin around an axis vertical to the ground, and they exhibit the opposite behavior of the well-known propeller design (HAWTs). The research found that VAWTs increase each other's performance when arranged in grid formations. Positioning wind turbines to maximize outputs is critical to the design of wind farms.

"The future of wind farms should be vertical," said Tzanakis. "Vertical axis wind farm turbines can be designed to be much closer together, increasing their efficiency and ultimately lowering the prices of electricity. In the long run, VAWTs can help accelerate the green transition of our energy systems, so that more clean and sustainable energy comes from renewable sources."

With the UK's wind energy capacity expected to almost double by 2030, the findings are a stepping stone toward designing more efficient wind farms, understanding large-scale wind energy harvesting techniques, and, ultimately, improving the renewable energy technology to replace fossil fuels more quickly as sources of energy.

Cost-effective way to meet wind power targets
According to the Global Wind Report 2021, the world needs to be installing wind power three times faster over the next decade in order to meet net-zero targets and avoid the worst impacts of climate change.

"Modern wind farms are one of the most efficient ways to generate green energy, however, they have one major flaw: as the wind approaches the front row of turbines, turbulence will be generated downstream," said Joachim Toftegaard Hansen, lead author of the report and Bachelor of Engineering graduate. "The turbulence is detrimental to the performance of the subsequent rows.

"In other words, the front row will convert about half the kinetic energy of the wind into electricity, whereas for the back row, that number is down to 25 to 30%. Each turbine costs more than £2-million/MW. As an engineer, it naturally occurred to me that there must be a more cost-effective way."

The study, published in the International Journal of Renewable Energy, is the first to analyze many aspects of wind turbine performance comprehensively with regard to array angle, direction of rotation, turbine spacing, and number of rotors. It is also the first research to investigate whether the performance improvements hold true for three VAWT turbines set in a series.

"The importance of using computational methods in understanding flow physics can't be underestimated," said Dr. Mahak Mahak, co-author of the article and senior lecturer in ECM. "These types of design and enhancement studies are a fraction of the cost compared to the huge experimental test facilities. This is particularly important at the initial design phase and is extremely useful for the industries trying to achieve maximum design efficiency and power output."
