Today's global manufacturing operations run 24/7, requiring
exact replication of products and processes in all regional settings. To remain
profitable providing competitive products and services, any operation must
maximize uptime and productivity while ensuring dependability and quality. In
addition, regardless of industry or marketplace, industrial applications
require flexible manufacturing systems that enhance reliability while
minimizing downtime. Given the challenges in this global competition, only the
most disciplined manufacturing operations can survive, largely by following
proven manufacturing practices that deliver high quality, reliable products
within cost effective environments.
Operating within these challenging market conditions, design
engineers cite numerous criteria when selecting motors across a broad range of
applications. Design decisions may turn on a single (or combination of
multiple) criteria such as cost, torque, speed and power, reliability and
durability, unit size, space utilization and installation hindrances, heat
dispersion and temperature control, energy efficiency along with noise levels
and adherence to project specifications and requirements.
In one unique design challenge, Asten, a Brazilian manufacturer,
sought a motor worthy of its ambitious plans to develop new products for the dental,
agricultural, fitness and medical markets. After rigorous vendor review, the
company asked Bosch's Industrial Business division to deliver the CEP motor
F006.WM0.310. Their decision was based
on superior product performance and the suppliers breadth and depth of
engineering support. Working together, the partners assembled dual engineering
teams and developed exacting technology to further refine the CEP motor in a
linear actuator assembly designed to drive dental chair position according to customer
Together Asten and Bosch engineering teams developed a
linear actuator assembly composed of Bosch's DC electric motor (24V DC), a
spindle and a drive bushing. The actuator was tested and approved for 6.000 Nm
or 600 Kg. This DC motor (F006.WM0.310) is the most robust DC motor in the CEP
family, with 48 Nm at 45 RPM. After final operational verification testing was
complete, the linear actuator assembly was sold to regional and global markets confirming
Based upon initial success in penetrating new markets with
the dental chair, the partners decided to explore other possible applications
for DC motors. Under joint design and development, the CEP motor was integrated
into Asten manufacturing operations, to enable the creation of new products
housing a DC motor improving performance across a new set of medical, fitness
and dental applications. Further success has been realized through the development
of an expanding product line including: adjustable hospital beds, surgical
tables, mats for cardiac evaluation and evolving new products customized
according to client specifications.
Powerful Dual Advantage
While Asten manufacturing has traditionally enjoyed a
technically sound and well-established engineering operation in Brazil,
the partnership with Bosch has added a new and powerful global dimension to
their manufacturing operations. Together the teams project engineering depth,
manufacturing strength, new product innovation, reliable technology and global
reach for a rapidly expanding customer base across a growing set of industrial
applications. Besides the engineering advancements, the DC motor linear
actuators deliver lower power consumption; low noise level compared with AC
motors and hydraulic systems, fewer maintenance requirements, lower
electromagnetic emission within CE certification, ecologically advanced
operation and reduced overall cost of ownership to a rapidly growing new
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
