The first in a new family of low cost, digital brushless motor
controllers, the DEC Module is a compact and powerful plug-in module
incorporating all the elements necessary to drive a sensored brushless dc motor
up to 48W. Measuring just 0.95 x 0.80
inch the DEC Module can be conveniently mounted onto any printed circuit board
either by socket terminal strips or by soldering directly onto a printed
circuit board. A complementary
evaluation board is available to facilitate the initial evaluation
process. The DEC 24/2 plug-in module was
designed to eliminate the step of developing a brushless motor controller from
scratch. The proprietary firmware can be
tailored to address a wide variety of applications. The DEC Module 24/2
provides a low cost, easy to integrate, pre-packaged brushless motor control
solution. The standard 0.100 pitch
pinout makes it easy to integrate into any printed circuit board design. More specific, mechanical designers can
quickly get their brushless motor up and running without having to design or
develop their own controller. There are
a variety utilities and I/O functions, inclusive of set speed values (500 -
80,000 rpm), direction, enable and status. There is also a wide range of
protection features built in; over current, under current, over voltage, under
voltage, thermal overload, current limits, invalid hall sensor and locked rotor
protection to name just a few.
Essentially, the DEC module provides a seamless brushless motor control
solution. A designer can go directly
from the evaluation stage to production by simply laying out their printed
circuit board accordingly; thereby bypassing the electronic control development
step. Currently there is no control product like the DEC Module 24/2 on the
market to compare it to - this concept is unique. The DEC Module 24/2, and all its I/O and
protection features can be initially evaluated with a complementary evaluation
board. The designer can then chose which
features are desirable for his application and tailor the firmware to his
application. The compact footprint, 0.95 x 0.80 inch, conveniently mates
(plug-in) with a standard printed circuit board design via socket terminal
strips or by direct soldering onto a printed circuit board.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
