2,b shows the electrical equivalent circuit of the furnace as an electrical transformer whose secondary winding
has two short-circuited turns with a common branch III located between nodes 2 and 3 (see Fig.
The leakage inductance test is carried out by shorting the secondary winding
and measuring the primary inductance.
The first geometry, Figure 5a, was an L-L core with the primary and secondary windings
on the same leg.
where [n.sub.Pr] and [n.sub.sec] are number of primary and secondary windings
turns, respectively, [U.sub.D3] is voltage drop across the diode D3.
Vector calculations and trigonometric properties were used to obtain the ratios of the secondary windings
that would allow obtaining five outputs of the same magnitude but phase shifted by 72 degrees.
In selecting the inducting load to the secondary winding
in the circuit of the transformer you muse uncheck the capacitor in the RLC branch of Figure 7 to select the inductive load than write the values of the inductor or capacitor you want of your desired.
Transformers are called for in a simple language and prototype device consists of two sets of primary and secondary windings
and magnetic square around the sheets of iron core transformers.
This is considered as a disadvantage for wave winding, but this may be corrected by connecting capacitors in the secondary winding
. Table 2, presents the values of mechanical force, efficiency, power factor, in the nominal operation of the motor.
Due to the larger inductance from the increased diameter of the windings, the secondary winding
was only a few turns.
When signal current goes through the primary winding, it generates a magnetic field which induces a voltage across the secondary winding
. Connecting a load to the secondary causes an AC current to flow in the load.
Since the channel is a short circuited secondary winding
with a low resistance, a large current exists in and heats the metal in the channel.
The secondary winding
consists of copper rods in an iron core.
