The latest in the Trust Automation drive line, the TA330 offers configuration for three-phase dc brushless servo motors using Hall Effect sensors, three-phase ac brushless motors with sinusoidal commutation, single-phase dc brushed servo motors in bridged mode, and brushless linear motors. Its zero cogging, lack of torque ripple, and smooth motion make it perfect for "very high resolution" inspection systems, metrology instruments and medical applications. With a 24V input for powering logic and bias supplies, it has low electrical noise, yet runs at 150V, 900W continuous (2700W peak), and offers on-the-fly torque control changes. An internal logic and bias supply option is available, too. It measures 14.9 inches (37.9 mm) x 7.7 inches (19.5 mm) x 4.7 inches (11.9 mm) Trust Automation Inc.http://rbi.ims.ca/4928-629
NASA and Boeing developed a huge, carbon composite cryogenic fuel tank for deep space missions, and started testing it last month. The 18-ft cryotank will enable heavy-lift launch vehicles to send both humans and robots into deep space.
