Basic Concepts in Rotating Machines topics include: Rreluctance motor, synchronous motors, singly and doubly excited systems, torque production, rotating machines terms and rotating magnetic field. Rotating machines have four main parts: Mechanical stator: The stationary part of the machine Electrical field winding: The rotating magnetic field component Mechanical rotor: The rotating part of the machine Electrical armature winding: The current producing component Windings: All rotating electrical machines have two windings, one on the stator and one on the rotor. The winding that... Show more
