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

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“

General Motors was founded in September of 1908 by William Durant during a time that there were less than 8‚000 in the United States. Durant was already known in Flint‚ Michigan for his horse drawn vehicles. “At its inception GM held only the Buick Motor Company‚ but in a matter of years would acquire more than 20 companies including Oldsmobile‚ Cadillac‚ and Oakland‚ today known as Pontiac.”(History & Heritage-Creation‚” 2014) General Motors set the tone in the automobile industry with design

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

Introduction The Toyota Motor Company Limited was established in 1937 by Kiichiro Toyoda. Kiichiro’s father was Sakichi Toyoda who established the Toyoda Automatic Loom Works. Initial capital for development and test building first automobiles was received by selling the patent rights of one of Sakichi Toyoda’s machines to Platt brothers from United Kingdom. In the history of the Toyota Motors was only one strike in 1950. However this strike brought together the managers and labour to have principles
