Design of Induction Motors Introduction: Induction motors are the ac motors which are employed as the prime movers in most of the industries. Such motors are widely used in industrial applications from small workshops to large industries. These motors are employed in applications such as centrifugal pumps‚ conveyers‚ compressors crushers‚ and drilling machines etc. Constructional Details: Similar to DC machines an induction motor consists of a stationary member called stator and a rotating

Chapter (11) Synchronous Motors Introduction It may be recalled that a d.c. generator can be run as a d.c. motor. In like manner‚ an alternator may operate as a motor by connecting its armature winding to a 3-phase supply. It is then called a synchronous motor. As the name implies‚ a synchronous motor runs at synchronous speed (Ns = 120f/P) i.e.‚ in synchronism with the revolving field produced by the 3-phase supply. The speed of rotation is‚ therefore‚ tied to the frequency of the source. Since

EXECUTIVE SUMMARY In the case of Assessing a Company’s Future Financial Health‚ the case concentration is on SciTronics‚ a medical device company‚ performance measures based on the organization’s three primary financial data sources in Exhibit 1 & 2. Utilizing the 9 steps of corporate financial system‚ I will be able to analyze the financial health of the company to assess whether it will remain balance over the ensuing 3-5 years. The measures are grouped by focusing on “Financial Ratios” such as:

Ford Motor Company is one of the greatest automobile manufacturers of all time. They started under Henry Ford in Detroit‚ Michigan. Ford had a skill for craftsmanship when he built an experimental car in 1896. It was a twin cylinder engine with potential of 20 mph. In 1899 he left his job in order to organize the Detroit Automobile Company. Ford’s first production was in 1903‚ the Model A‚ with an under the floor engine selling for $850. In the first season it sold 1‚708 cars. After World War

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

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“
