The asynchronous induction motors are the most commonly used motors in ship electric drives. The investigation of their magnetic fields is an essential part of their working regimes exploring. The magnetic fields of an asynchronous induction motor are studied using an experimental method that enables the screening of the magnitude and the shape of the magnetic fields in the stator and in the rotor, separately and in joint action in different working regimes of the motor.
