dunkerDunkermotoren expanded its portfolio with an interesting, coordinated solution, consisting of a controller for high currents and a brushless DC motor for use in battery powered applications (12 / 24 V) or low voltages. The 1 quadrant controller is matched exactly to the brushless 3 BG-phase motors of the manufacturer with an output power up 500 W. A permissible continuous output current of 60 A and short-term peak currents of up to 100 A (2 s) can be realized with a supply voltage of 8 30-V.

The parameter sets controller lock, counterclockwise, clockwise, two fixed speeds and speed mode can be selected via a DIP switch, or via digital inputs. In addition, the speed can be set via an analog input either 0 10-V, 0-20 mA or PWM. Via a USB interface, these sets of parameters can be configured. A speed potentiometer scales the analog input between 0-100% and sets a defined speed or power. Via digital outputs, different engine and system information to lead out. A rugged and durable case allows the application in harsh environments.

Twice as far as electric drive with a lithium-sulfur batteries Wednesday 03. April 2013 08: 59 Research Report have electric cars are still in a difficult position on Germany's roads. The cars are too expensive and their range is too low. But now a breakthrough in performance, cost lithium-sulfur battery has succeeded: it is much more efficient and cheaper than the previously-known lithium-ion version. But so far, it is because of their short lifetime to find yet in the car. That could change in the near future. Scientists at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden have now developed a new battery design that recharges the lithium-sulfur battery is increased by a factor of seven. read more

Optimal microscope imaging during surgery due to capacitive sensor Monday 22. April 2013 16: 21 In surgery a perfect view of the surgical field is essential. At this point, the physician is often supported by a surgical microscope. To maintain the field of view of the microscope, stable, a high-precision capacitance sensor is used. The optics of the operating microscope is mounted on tripod long arms. This allows the surgeon the best possible positioning of the microscope and the operating crew freedom of movement. The long boom requires constant correction on the hinges to keep the vision and focus range of the microscope for the physician stable. This is the capacitive measuring system "Capa NCDT 6019"By Micro-Epsilon employed. read more
LED and laser light for small cross sections in medical Tuesday 16.
