A DC machine is an electromechanical device that operates either as a motor or a generator, converting mechanical energy into direct current (DC) electrical energy … Read more
Induction motors are often described as “rotating transformers” due to their fundamental similarities in their operating principles and energy transfer. To understand this analogy, let’s … Read more
Open-circuit and Short-Circuit Tests of transformers are carried out to assess core losses, magnetizing current, impedance, and copper losses. These tests provide essential insights into … Read more
An AC motor is an electrical machine that transforms alternating current into mechanical rotation. AC motors, also known as alternating current motors, are widely used … Read more
The k-factor of the transformer is a weighting of the harmonic load currents based on their effects on transformer heating, derived from ANSI/IEEE C57.110. Transformers … Read more
This article describes two important transformer ratios: turn ratio and voltage transformation ratio. Transformers are fundamental components in electrical engineering, playing a crucial role in … Read more
Definition: A step-up transformer transforms the low voltage on the primary side to the high voltage on its secondary side. The current on the secondary … Read more
What is an Induction Motor? An induction motor, also known as an asynchronous motor, is a type of AC electric motor that is widely used. … Read more
Armature reaction refers to the effect of the magnetic field produced by the armature current on the main magnetic field of the DC machine. A … Read more
This article describes the working and diagram of an auto transformer. The autotransformer transforms voltage and current by changing the ratio of voltage transformation. Auto … Read more
