Effective voltage induced into any stator winding depends on which two factors?

The effective voltage induced into any stator winding is primarily influenced by the angular position of the rotor and the rotor itself. The angular position refers to the orientation of the magnetic field relative to the winding at any given moment, which is crucial in determining how effectively the magnetic field interacts with the stator winding to induce voltage.

The rotor, which is part of the rotating element in an electric machine, alters the magnetic field's strength and orientation that the stator winding "sees." This interaction between the rotor's magnetic field and the stator winding is integral to electromagnetic induction, following Faraday's law of electromagnetic induction. When the rotor rotates, it creates a changing magnetic field, and the effective voltage induced in the stator winding is maximized based on the precise alignment of the rotor at any instance.

The other options do not accurately identify the primary factors influencing induced voltage in stator windings. Torque and pressure relate more to the mechanical aspects of the motor's performance rather than the electromagnetic induction process, while electrical resistance and inductance are important to the characteristics of electrical circuits but do not directly contribute to the effective voltage induced in the windings. The relationship between angular position and rotor conditions is central to the understanding of how electric machines operate in
