MDriveÂ® linear systems integrate a stepping motor
based linear actuator with driver, controller and optional encoder to form a
single compact, powerful and easy to use linear motion product that delivers high
accuracy and unsurpassed repeatability. Two linear actuator styles are
available: external shaft and non-captive shaft, with a load limit of up to 200
lb. Precision rolled lead screws are corrosion resistant stainless steel with
Teflon coating option. MDrive Linear Actuators can reduce linear motion machine
cost, size and time-to-market while delivering high performance and
reliability. MDriveÂ® Linear Actuator advantages to design engineers include: reduced workload - an
integrated linear motion solution eliminates an Engineer's task of researching
and specifying individual components; compact design - Integrated motor,
mechanicals and electronics form a single compact unit that dramatically
reduces the space requirements in linear motion applications; versatility - for
a wide range of linear motion applications, several MDrive Linear Actuator
versions and styles provide a rich choice of features at low cost; as well as simplified
installation/setup - minimized wiring and production time along with
user-friendly software contribute to easy integration of MDrive Linear Actuator
products. The MDrive Linear Acuators also offer the availability of a rugged internal encoder
integrated with the screw; integration
of actuator, motor, drive, encoder and programmable motion controller complete
with I/O; and AccuStepTM motion control technology that eliminates loss of
synchronization - the motor cannot stall; maintains constant motor torque with torque
mode, giving MDrive Linear Actuators the ability to apply a regulated
force; and reduced motor heating and power consumption with Variable Operating
Current, where the unit only draws the current required to complete a move.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
