In power engineering, winding factor provides a way to compare of the effectiveness of different designs of stators for alternators.Winding factor is the ratio of electromotive force (EMF) produced by a stator having a short-pitch, distributed, or skewed winding, with a stator having full-pitch, concentrated, and non-skewed, windings.
The winding height can be estimated using the formula: ... Geometry aspects for determining the mechanical fill factor; A= insulated winding space.
Fig. 1 L P σ and L S σ are primary and secondary leakage inductances expressed in terms of inductive coupling coefficient under open-circuited conditions.. The magnetic circuit's flux that does not interlink both windings is the leakage flux corresponding to primary leakage inductance L P σ and secondary leakage inductance L S σ.
This is exactly the value estimated by the formula stated earlier. EXAMPLE: Torque applied at different diameters , K v (rpm/V) {\displaystyle K_{\text{v (rpm/V)}}} = 3600 rpm/V ≈ 377 rad/s/V , K T {\displaystyle K_{\text{T}}} ≈ 0.00265 N.m/A (each calculatable if one is known) , V = 2 v, I a {\displaystyle I_{\text{a}}} = 2 A, P = 4 W ...
The amount of mutual inductance between the two windings, together with the Q factor of the circuit, determine the shape of the frequency response curve. The advantage of the double tuned transformer is that it can have a wider bandwidth than a simple tuned circuit.
In this state the armature flux is pushed completely out of the rotor. The state is very brief, as the current in the damper winding quickly decays allowing the armature flux to enter the rotor poles only. The generator goes into transient state; in the transient state the flux is still out of the field winding of the rotor.
Copper loss is the term often given to heat produced by electrical currents in the conductors of transformer windings, or other electrical devices. Copper losses are an undesirable transfer of energy, as are core losses, which result from induced currents in adjacent components.
In a typical application the term "flux linkage" is used when the flux is created by the electric current flowing through the coil itself. Per Hopkinson's law, =, where MMF is the magnetomotive force and R is the total reluctance of the coil.
