statorproduced

Statorproduced is a term used to describe outputs, effects, and phenomena that originate in the stator of an electric machine, such as a motor or generator. The term emphasizes that the source of these outputs is the stationary part of the machine—the stator windings, core, and associated circuits—rather than the rotor.

In operation, the stator generates a magnetic field by applying balanced three-phase currents to its windings. This stator-produced field can be a stationary field in a simple sense or a rotating magnetic field in machines designed to produce rotation. In induction machines, the rotating stator field induces currents in the rotor, producing torque. In synchronous machines, the stator field locks to a constant speed set by the supply frequency, defining the machine’s synchronous speed.

Common examples of statorproduced effects include the stator’s electromotive forces (EMFs) and currents, the magnetic flux distribution within the machine, and the resulting torque generated through rotor interaction. The stator also produces losses and heat through copper resistance, core eddy currents, and hysteresis, all of which influence efficiency and thermal performance. Harmonics arising from winding distribution, slotting, and magnetizing effects are additional stator-produced phenomena that can affect torque ripple, noise, and vibration.

Design considerations related to statorproduced behavior focus on optimizing winding arrangement, insulation, and core geometry to achieve uniform flux, minimize losses, and control harmonic content. This includes methods to reduce cogging torque and torque ripple, improve efficiency, and manage thermal limits. Understanding statorproduced effects is essential for analyzing machine performance, control strategies, and reliability in industrial motors and power generators.
