: Run on alternating current and are further divided into:
: 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.
: Convert mechanical energy into electrical energy.
: The rotor rotates at the exact same speed as the stator's magnetic field.
(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
At their most fundamental level, electrical machines rely on the interplay between , magnetic fields , and mechanical motion .
: While static (no moving parts), they are considered electrical machines because they use magnetic fields to change voltage levels. 2. By Power Supply
Electrical machines are broadly classified by their function and the type of power supply they use. 1. By Function
