What is the difference between stall torque and braking torque in DC motor?

Posted: 12 Apr 2011 09:49 AM PDT

Hello,
In DC motor specification and data sheet, the stall torque is mentioned. The stall torque is considered as a toque produced when the speed is zero. I would like to know if there is a difference between stall torque and braking torque?
best wishes,

European Online Recruitment Increases 26 Percent Year-over-Year; Most Rapid Pace Duri

Posted: 12 Apr 2011 09:22 AM PDT

The Monster Employment Index Europe records 26 percent year-over-year growth, the most rapid pace seen during the current economic cycle
Industrial production related sectors lead the Index in annual growth in March with a 64 percent rise in production, manufacturing, maintenance and repair
Financial services sector notes positive recruitment trends in March, growing five percent on an annual basis
Arts, entertainment, sports, leisure continues to decline and remains the only sector to chart a substantial year-over-year decline
Germany continues to lead all countries in annual growth, at 45 percent
The Monster Employment Index Europe is a monthly analysis of millions of online job opportunities culled from a large, representative selection of corporate career sites and job boards across Europe, including Monster.

"Manufacturing and exports remain a key driver of recruitment across the continent, highlighted through strong growth within industry-related sectors in this month's Index," commented Alan Townsend, Vice President of Business Operations at Monster Europe. "In contrast, it is still very apparent that household and government spending trends are continuing to weigh on recruitment activity across the arts and public sector industries, while business and professional services mainly trend higher."

Accounting, audit, taxes (up 14 percent), one of the more moderate trending sectors during the economic recovery, registered a substantial rise in online recruitment levels in March
Banking, finance, insurance (up five percent) exhibited some gains in online demand, contrasting with its one percent increase in February, reflecting positive sector recruitment developments across a number of countries, including Belgium, France, Italy, and Netherlands
Engineering (up 42 percent) charted further rise in annual growth, reflecting an increasingly competitive hiring climate for technically advanced professionals as industrial production and design activity across Europe continued to grow
Arts, entertainment, sports, leisure (down 20 percent) was the only sector to register an annual decline in the Index; combined with slowed annual growth for Sales (up seven percent), suggesting household discretionary spend remains limited

Help on Smart Machine

Posted: 12 Apr 2011 07:02 AM PDT

Hello,
I am a student from India i am planning to do a Smart CNC Turning Center
Such that it will automatically adjust itself the Cutting Parameter based on Spindle Speed and material chosen!
Does any one have an idea on how to do??

I have a plan to do based on young's modulus of the material

On silly question is does Youngs Modulus vary depending on size of material? I hope its definitely no
Hope it vary if defect is there

Also is there any formula to compute best Depth of Cut and Feed Rate based on Youngs Modulus of the Material???

Will this thing work??
