Magnetizing

2. ELECTRIC MOTORS - Bureau of Energy Efficiency

However, there is no corresponding reduction in the magnetizing current,which is propor-tional to supply voltage with the result that the motor power factor reduces, with a reduction in applied load. Induction motors, especially those operating below their rated capacity, are the main reason for low power factor in electric systems.

LECTURE 34 HIGH FREQUENCY TRANSFORMER - Walter Scott, …

• Magnetizing inductance, L M , represents energy stored in the magnetic core and in small air gaps which arise when the separate core halves forming a closed magnetic loop core come together. In the equivalent circuit of a real transformer, mutual inductance appears in parallel with the primary windings only. The energy stored in the
