Blondel's Two Reaction Theory (Theory of Salient Pole Machine): part 1 It is known that in case of nonsalient pole type alternators the air gap is uniform. Due to uniform air gap, the field flux as well as armature flux very sinusoidally in the air gap. In nonsalient rotor alternators, air gap length is constant and reactance is also constant. Due to this the m.m.f.s of armature and field act. 25/12/ · This two reaction theory was given by Professor Andre Blondel so it is named as Blondel two reaction theory. Due to this, the MMFs of armature and field act upon the same magnetic circuit all the time hence can be added diyqcneh.com in salient pole type alternators, the length of the air gap varies and the reluctance also varies. This theory isalsoknown as the two-factor ordual-factor theory. Thepremise ofFrederick Herzberg’s theory is that the concept of motivationis dividedintotwo aspects:hygiene and diyqcneh.com

Let Ed and Eq be the induced e. Hence the direction of E f is also known. Skip to content Two Reaction Theory was proposed by Andre Blondel. The MMF F S produces stator magnetic field B S long the direction of Fs. Download pdf. The direct axis flux path involves two small air gaps and is the path of the minimum crosshead assembly drawing pdf. Derivation of the demagnetizing action of the armature reaction for the general case will be based on the notations and symbols shown in Fig.25/12/ · This two reaction theory was given by Professor Andre Blondel so it is named as Blondel two reaction theory. Due to this, the MMFs of armature and field act upon the same magnetic circuit all the time hence can be added diyqcneh.com in salient pole type alternators, the length of the air gap varies and the reluctance also varies.

Mannan Page 1 of 11 Alternators Two Reaction Analyses [2, Ch. 16] A multipolar machine with cylindrical rotor has a uniform air-gap, because of which its reactance remains the same, irrespective of the spatial position of the rotor. However, a synchronous machine with salient pole or projecting poles has non-uniform air-gap due to. Salient pole alternators and Blondel's Two Reaction Theory. The details of synchronous generators developed so far is applicable to only round rotor or non-salient pole alternators. In such machines the air gap is uniform throughout and hence the effect of mmf will be same whether it acts along the pole axis or the inter polar axis. Hence reactance of the stator is same throughout and hence it. Two Reaction Theory (Blondel's Theory): In salient pole type alternators the length of the air gap varies and the reluctance also varies. Hence the armature flux and field flux cannot vary sinusoidally in the air gap. The reluctances of the magnetic circuits on which diyqcneh.com act are different in case of salient pole alternators. Hence the armature and field m.m.f.s cannot be treated in a simple. Two Reaction Theory of Salient pole Synchronous Alternator. REGULATION OF SALIENT POLE SYNCHRONOUS MACHINE-BLONDEL’S TWO REACTION THEORY: In case of salient pole machines the air gap is not uniform in length around the inner periphery of the armature. It is minimum along the polar axis and maximum along the inter polar axis. Lindemann theory breaks down for two main reasons: i) The bimolecular step takes no account of the energy dependence of activation; the internal degrees of freedom of the molecule are completely neglected, and the theory consequently underestimates the rate of activation. ii) The unimolecular step fails to take into account that a unimolecular reaction specifically involves one particular form File Size: 26KB. Two Reaction Theory – Salient Pole Synchronous Machine Two Reaction Theory was proposed by Andre Blondel. The theory proposes to resolve the given armature MMFs into two mutually perpendicular components, with one located along the axis of the rotor of the salient pole. It is known as the direct axis or d axis component. Download Full PDF Package. This paper. A short summary of this paper. 30 Full PDFs related to this paper. READ PAPER.
