The Flux Drive
08ASD (adjustable speed drive) is a mechanical power-transmission device that
provides soft-start and variable speed (energy savings) to centrifugal load
applications such as pumps and blowers.
The unit is made up of two components - an induction rotor and a
magnetic assembly. Adjustable speed is
achieved by controlling the overlap of an organized magnetic array, as it spins
around an induction rotor. When the magnetic assembly and the rotor are
disengaged, slip increases and the output speed decreases. As the magnetic assembly and the rotor are
full engaged, the torque increases to 98.5 percent of the input speed. It
offers up to 30-50 percent energy savings ; reduces power required to operate
at variable speed (compared to VFD's); eliminates damaging harmonic frequencies;
eliminates the need to install electronic filtering devices; reduces cost of
specialized personal to install, tune
and maintain the speed control device; handles speed control on Low, Med and
High voltage applications without requiring step down transformers or filters;
offers cost-effective operations in harsh environments (saltwater, gases, etc.).
Power Transmission is across an air-gap, therefore no touching parts to wear
out. The Flux Drive
product uses a unique patented magnetic circuit that is created by combining
induction rotor technology and permanent magnets to create a constant magnetic
flux current that closely follows motor theory and scaling. The company says this
technology is notassociated with the
older eddy current technology which is found in other magnetic couplings. The constant magnetic circuit operates at
higher torque and horse power in a smaller footprint with less slip than other
The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
