New Specifications Guide on Extended Life
Brush DC Motors
Crouzet Motors has introduced a new 24 page specifications
guide focusing on the DCmind Brush Motor series. The full color
brochure provides comprehensive information on this motor series
as well as the brand as a whole.
In addition to offering detailed product features and benefits, the brochure
also provides a cutaway view, an informative chart illustrating motor sound
compared to standard recognizable
sounds, and a handy selection guide
that makes it easy to review and choose
the appropriate model by output power, torque, speed and gear reduction
style and range. Complete specifications for performance curves, dimensions, and options on all five models
include 15, 25 and 55 watt motors with
a 42 mm diameter, and 55 and 104 watt
motors with a 63 mm diameter. DCmind Brush Motors support 12,
24 and 48 volt power supplies and are available with several accessories and adaptations, including rear brake, optical or Hall effect
encoders (1 or 2 channels), connectors and cables, as well as custom voltage, speed and power, and shaft dimensions and material.
"The DCmind Brush Motor series is currently our hottest product
and this brochure does a great job leaving nothing unanswered,"
said John Morehead, national sales manager for Crouzet Motors.
"With its amazingly quiet operation and high efficiency, this motor is a true innovation, especially for applications where low noise
level, long battery life and extremely long service life are critical."
In addition to its low sound level, the motor meets several standards in applications for medical (IEC 60601-1), office equipment
(IEC 60950), and household appliances (IEC 60335). All the DCmind Brush motors are approved in accordance with UL 10004-1
and CE, and are RoHS compliant. They come with standard IP65
levels of environmental protection and can be made available in
IP67 and IP69K versions. DCmind Brush Motors can also be used
in a variety of other applications such as pumps and valves in mass
Rare Earth Production Rises in Q4 at Molycorp's
Mountain Pass Facility
Molycorp, Inc. has reported that rare earth production in the
fourth quarter of 2014 at its Mountain Pass, Calif. facility increased
year-on-year and nearly doubled that of the preceding quarter.
Mountain Pass completed Q4 of 2014 with 1,328 metric tons (mt)
of rare earth oxide (REO) equivalent production. That compares to
1,034 mt in Q4 of 2013 and 691 mt in Q3 of 2014. Full year 2014
production totaled 4,785 mt, compared to 3,473 mt in 2013. Perunit cash production costs at Mountain Pass also declined sequentially in Q4 of 2014.
Company officials said that the higher production volumes they
expect at Mountain Pass in 2015 should coincide with relatively
strong demand the Company is seeing for products such as the
magnetic rare earth material Neodymium/Praseodymium, Lanthanum and Light Rare Earth Concentrate (LREC). Molycorp processes
Mountain Pass LREC at vertically integrated downstream processing
facilities into a variety of value-added engineered materials, including
rare earth magnetic materials for multiple downstream markets and
vehicle emissions catalysts that consume cerium and other materials.

The Company said that its onsite Chlor-Alkali plant at Mountain
Pass is performing well in producing hydrochloric acid (HCl), a key
chemical reagent used in rare earth production at Mountain Pass.
Moreover, commercial availability also has improved, such that HCl
currently is no longer a significant constraint to production. Molycorp's Chlor-Alkali plant helps to lower cash production costs by
generating chemical reagents onsite, reducing waste water disposal
costs, and further shrinking the environmental footprint of rare
Company officials reported that repairs of construction-related
issues with the facility's newly expanded Leach system are ongoing. Once fully operational, that system is expected to increase rare
earth production and lower operating costs.
"We were pleased to see our production increase in the fourth
quarter relative to the preceding quarter and year-on-year," said
Geoff Bedford, president and CEO of Molycorp, Inc. "Optimization
at Mountain Pass is ongoing, but our Q4 production demonstrates
momentum in the right direction. Rare earth pricing softened in Q4
with market uncertainty surrounding release of final details of China's ongoing reforms to rare earth mining, separation, and export
regulatory policies. However, given the relatively strong internal and
external demand we are seeing for many Mountain Pass products,
continuing to boost production there is a top operational priority."
Significant Rare Earth Element Claim Discovery in
RioSol SAC LLC and Compania Minera Rio Sol SAC (RioSol) has
announced a significant rare earth element and poly-metallic
claim discovery in Peru, with reports indicating the 10-kilometer
claim as among the largest rare earth claims in Peru containing
both light rare earth elements (LREEs) and heavy rare earth elements and metals (HREEs).
Third-party geology and geochemical analysis indicates the claim
is the largest in Peru, with further exploration warranted to further
delineate the size and scale of the claim.
The geology consultants leading the project were Rildo Oscar Rodriguez and a Peruvian rare earth expert, both of Lima. According
to Mr. Rodriguez, "The claim is one of the newest rare earth finds
in all of Latin America that contains both light and heavy rare earth
elements and metals, as well as copper, zinc, aluminum and other
base metals. It proves that the potential for rare earth elements exists outside of China with significant opportunity for development
of new production in a mining-friendly country."
Currently, approximately 90 to 95 percent of rare earth elements
are located in China. Having a supply source in the Americas for
commodities used today and in the future will be important for
geographic diversity and commercial competition.
Over the past two years, RioSol has been testing the claim, initially focused on base metals. However, rare earths were discovered
in recent field explorations and assay results, and further testing
was conducted. Both the rare earth geologist and RioSol general
manager Max Cruz will be presenting the results of the discovery at
PROEXPLO 2015, the 9th International Congress of Prospectors and
Explorers in May.
The claim area is located approximately 95 kilometers northwest
of Cusco, Peru.
Rare earth elements are a group of 17 chemical elements that
occur together in the periodic table. The group consists of yttrium
and the 15-lanthanide elements (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium,
terbium, dysprosium, holmium, erbium, thulium, ytterbium and lu-
