Summary After three years bailed out by the federal government‚ General Motor Co. set a goal of making $10 billion a year which is an unthinkable goal. In 2012‚ GM report 2011 net income about $8 billion and its highest ever campare to 2010 with gain nearly twice which is $4.7 billion are growth in China and strong profit in North America. GM also aims over next several years to raise its profit margin to 10% from current margin of about 6% and would be among the highest in the auto industry. The

A DC motor is a mechanically commutated electric motor powered from direct current (DC). The stator is stationary in space by definition and therefore so is its current. The current in the rotor is switched by the commutator to also be stationary in space. This is how the relative angle between the stator and rotor magnetic flux is maintained near 90 degrees‚ which generates the maximum torque. DC motors have a rotating armature winding but non-rotating armature magnetic field and a static field

The speed of an asynchronous motor rotating field and thus its rotor speed depends on the number of pairs of poles in the stator field .the rotor speeds n are lower than the table values by the amount of the relevant slip speed ns. Motors are designed with up to three stators windings‚ which have different number of pairs of poles. They can therefore run at up to pairs of poles. They can be in any desired ratio to one another. A pole-changing switch is used to changing poles for the desires speed

GROUP 4 JULY 26‚ 2013 EE 4101 ENGR. KENNETH F. FAJILAN Reluctance Motor Introduction A reluctance motor is a type of electric motor that induces non-permanent magnetic poles on the ferromagnetic rotor. Torque is generated through the phenomenon of magnetic reluctance. There are various types of reluctance motor: Synchronous reluctance Synchronous reluctance motors have an equal number of stator and rotor poles. The projections on the rotor are arranged to introduce internal flux “barriers“

“Running is the greatest metaphor for life‚ because you get out of it what you put into it.” Oprah Winfrey came up with this empowering quote that actually holds true to running. Over the past few years there has been a peak of people starting to call themselves runners. It has been proven by researchers that even doing a minimum amount of running can potentially provide several health benefits. From preventing the common cold to helping someone fit into their jeans two sizes too small‚ running

Problem Definition John Bridges‚ the chief electrical engineer of Hamilton Oil Company‚ has concluded through motor testing that DMC competitors Spartan Motors and the Universal Motor Company of Canada offer the first and second choice motors on the market‚ respectively. DMC’s position as the third choice could prove quite detrimental to its market share because Hamilton is the largest active oil company in Canada‚ operating over 30% of producing wells‚ and Bridges is extremely influential in
