Magnetic loss in the stator is commonly referred to as "core loss" or "iron loss." This loss occurs due to the alternating magnetic field in the stator, which leads to energy dissipation primarily through hysteresis and eddy currents in the magnetic core material. Hysteresis loss is related to the magnetic properties of the material, while eddy current loss is caused by circulating currents induced in the core. Together, these losses reduce the overall efficiency of electromagnetic devices like motors and Transformers.

What is the name of an electric motor in which rotor and stator fields rotate simultaneously?
The electric motor in which the rotor and stator fields rotate simultaneously is called a "synchronous motor." In synchronous motors, the rotor is designed to rotate in synchrony with the rotating magnetic field produced by the stator. This type of motor is commonly used in applications requiring precise speed control and efficiency.

How energy is transferred from the stator to the rotor?
In an electric motor, energy is transferred from the stator to the rotor through the interaction of magnetic fields. When an electric current flows through the stator windings, it generates a rotating magnetic field. This rotating field induces a current in the rotor, creating a magnetic force that causes the rotor to turn and transfer mechanical energy.
What is stator magnetic axis and rotor magnetic axis?
The stator magnetic axis refers to the orientation of the magnetic field produced by the stator windings in an electric machine, such as a motor or generator. In contrast, the rotor magnetic axis is the orientation of the magnetic field produced by the rotor windings or permanent magnets. The alignment and interaction between these two axes are crucial for the operation of the machine, as they determine the torque and efficiency of electromagnetic energy conversion. Proper alignment ensures optimal performance, minimizing losses and maximizing output.

What is rotor in ac alternator?
A Rotor is a mechanism in the alternator that is driven by the pulley belt from the engine.which creates a magnetic field which causes voltage.Answer.The rotor does not 'create' a magnetic field. The emf induced in the stator winding is due to the residual magnetic flux of the rotor which cuts the stator windings as the rotor rotates.
