2 THEORY OF ELECTROMECHANICAL ENERGY CONVERSION

coupled for the purpose of changing the voltage and current levels. In the case of electric

machines, circuits in relative motion are magnetically coupled for the purpose of trans-

ferring energy between mechanical and electrical systems. Since magnetically coupled

circuits play such an important role in power transmission and conversion, it is impor-

tant to establish the equations that describe their behavior and to express these equations

in a form convenient for analysis. These goals may be achieved by starting with two

stationary electric circuits that are magnetically coupled as shown in Figure 1.2-1. The

two coils consist of turns N

and N

, respectively, and they are wound on a common

core that is generally a ferromagnetic material with permeability large relative to that

of air. The permeability of free space, μ

, is 4π × 10

−7

H/m. The permeability of other

materials is expressed as μ = μ

, where μ

is the relative permeability. In the case of

transformer steel, the relative permeability may be as high as 2000–4000.

In general, the flux produced by each coil can be separated into two components.

A leakage component is denoted with an l subscript and a magnetizing component is

denoted by an m subscript. Each of these components is depicted by a single streamline

with the positive direction determined by applying the right-hand rule to the direction

of current flow in the coil. Often, in transformer analysis, i

is selected positive out of

the top of coil 2 and a dot placed at that terminal.

The flux linking each coil may be expressed

The leakage flux Φ

is produced by current flowing in coil 1, and it links only the turns

of coil 1. Likewise, the leakage flux Φ

is produced by current flowing in coil 2, and

it links only the turns of coil 2. The magnetizing flux Φ

is produced by current flowing

in coil 1, and it links all turns of coils 1 and 2. Similarly, the magnetizing flux Φ

produced by current flowing in coil 2, and it also links all turns of coils 1 and 2. With

the selected positive direction of current flow and the manner in that the coils are wound

(Fig. 1.2-1), magnetizing flux produced by positive current in one coil adds to the

Figure 1.2-1. Magnetically coupled circuits.
