The matching transformers of different constructive fulfilling, a) a principle scheme of the <<the matching cylindrical transformer)), b) a principle scheme of the <<the matching disk transformer)), 1--the primary winding
, 2--the single turn inductor, 3--the sheet billet; c) the cylindrical and disk constructions photos; d) a single turn inductor with the conical inner bore
The reflected voltage URpri appears in the primary winding
when the diode D3 conducts the current of the secondary winding
The primary windings
are to be connected in the typical fashion (star or delta) since the input is three-phase.
Obtain a test coil designed to encircle the portion of the casting specified for Brinell hardness testing and having a primary winding
inductance of 5-8 milihenries.
However, copper is the primary winding
material in the Indramat design.
[V.sub.g] - [V.sub.b] = [V.sub.lo]' - V' (V' << [V.sub.lo]') Therefore, voltage of the primary winding
is unchanged and P ignores the RF and IF signals.
The replacement circuit of the generator with the lead to the primary winding
of the LPT is shown in Fig.
3(b)) and damps only the magnetomotive force created by the 1 and 7 windings, therefore, the magnetomotive forces developed by the 2,3,8 and 9 windings are not damped, because of this, the leakage inductance and, as a consequence, the voltage spikes in primary winding
According to phasor diagram, the 3-phase voltages are made from ac main phase and line voltages with fractions of the primary winding
turns which are expressed with the following relationships.
The primary winding
turns [N.sub.p] are 18 and the secondary winding turns [N.sub.s] are 50.
We measured the mutual inductance by passing an AC current of 2-5 A through the primary winding
of the test toroidal frame with no ring specimen in the solenoids and the air-flux compensator connected to the coils at the correct polarity.
A WPT system consisting of a U shape pickup on the vehicle and three wires as primary winding
is proposed for supplying movable vehicles .
