Rotating Magnetic Fields in Induction Motors
Induction motors operate by exploiting the principle of electromagnetic induction. A rotating magnetic field results within the motor's stator windings. This rotating field generates a current in the rotor windings, which in turn exerts more info a magnetic field. The interaction between these two fields leads to a torque that rotates the motor shaft.
Several aspects influence the strength of the rotating magnetic field, including the number of poles, winding configuration, and supply voltage. A higher supply voltage generally leads to a higher rotating magnetic field.
