Transformer Voltage Ratio
The voltage of the windings in a transformer is directly proportional to the number of turns on the coils. This
Transformer Theory of Operation
A transformer works on the principle that energy can be transferred by magnetic induction from one set of coils to
Transformer Efficiency
Efficiency of a transformer is the ratio of the power output to the power input, as illustrated by Equation. where
Transformer Impedance Ratio
Maximum power is transferred from one circuit to another through a transformer when the impedances are equal, or matched. A
Transformer Turns Ratio
Each winding of a transformer contains a certain number of turns of wire. The turns ratio is defined as the
Transformer Mutual Induction
If flux lines from the expanding and contracting magnetic field of one coil cut the windings of another nearby coil,
Starting a Synchronous Motor
A synchronous motor may be started by a DC motor on a common shaft. When the motor is brought to
Synchronous Motors
Synchronous motors are like induction motors in that they both have stator windings that produce a rotating magnetic field. Unlike
Single Phase AC Induction Motors
If two stator windings of unequal impedance are spaced 90 electrical degrees apart and connected in parallel to a single-phase
Induction Motor
Induction Motor Previous explanations of the operation of an AC motor dealt with induction motors. The induction motor is the
