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“

Case 2 Tata Motors 1. Describe the economic characteristics of the global motor vehicle industry. The 2008 financial crisis began in the American subprime mortgage crisis‚ eventually evolved into a global financial crisis. Most countries because of the impact of the financial crisis‚ leading to a sharp slowdown in consumer’s vehicle demand. Also‚ because of the financial crisis‚ the global motor vehicle industry experienced a full-scale market competition. Some small car companies to be phased

SISTEMAS DC Motors Catedrático: Ing. Gustavo Mendoza Leal Alumno: Alfredo Valdés Cárdenas Introduction A DC motor is a type of electrical machine that converts direct current into mechanical power by means of a magnetic field. DC motors are widely used in field applications because of their many advantages over AC motors such as speed control‚ high starting torque‚ quick starting‚ stopping‚ reverse and acceleration and free from harmonics found in AC. Applications of DC motors include but

The world’s population is growing at 1.1 per cent per year‚ having surpassed 7 billion people in late 2011. It is expected to rise to 9.1 billion people by 2050. This growth is unprecedented and is being felt mainly in the developing world. Due to the unprecedented growth rates being experienced and uneven distribution of population growth occurring it is resulting in huge amounts of pressure on the natural environment‚ drastic global inequalities and is affecting age structure and employment in
