: Convert mechanical energy into electrical energy.
: Most rotating machines consist of two main parts:
: Run on alternating current and are further divided into: Elektricne masine
: Convert electrical energy into mechanical motion.
(electrical machines) are electromechanical energy converters that use magnetic fields to transform mechanical energy into electrical energy (generators) or electrical energy into mechanical motion (motors). Core Principles and Components : Convert mechanical energy into electrical energy
At their most fundamental level, electrical machines rely on the interplay between , magnetic fields , and mechanical motion .
: The rotor rotates slower than the magnetic field (known as slip ). These are the most common industrial motors. Modern Trends in Technology Core Principles and Components At their most fundamental
: For motors, current in a wire creates a magnetic field that interacts with a second field (usually from a permanent magnet or electromagnet), producing a Lorentz force that turns the rotor.
