Elektricne Masine May 2026

: While static (no moving parts), they are considered electrical machines because they use magnetic fields to change voltage levels. 2. By Power Supply

: 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.

: Run on direct current. They often use a commutator to periodically reverse the current flow in rotor windings to maintain rotation. Elektricne masine

(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

: Electrically, machines are divided into the armature (where the main power is generated or consumed) and the field (which produces the necessary magnetic flux). Classification of Electrical Machines : While static (no moving parts), they are

: Convert electrical energy into mechanical motion.

: The stationary outer part, often containing field magnets or windings. Rotor : The rotating inner part supported by bearings. : Run on direct current

: The rotor rotates slower than the magnetic field (known as slip ). These are the most common industrial motors. Modern Trends in Technology
