The difference between stator and rotor stator and rotor are both components of motor. The significant difference between the rotor and the stator is that the rotor is the rotating part of the motor and the stator is the stationary part of the motor. Other differences between the stator and rotor are shown in the following comparison table. In the stator frame, the stator core and stator winding are parts of the stator. The frame supports the core of the stator and protects its three-phase winding. The stator core carries a rotating magnetic field generated by a three-phase power supply. The rotor is located inside the core of the stator. Squirrel Cage and phase-wound rotor are rotor types. The rotor winding is excited by a DC power supply. The magnetic field winding induces a constant magnetic field in the rotor core. The definition of the comparison table stator the stator is the static part of the motor. The main function of the stator is to generate a rotating magnetic field. Stator frame, stator iron core and stator winding are the three parts of the stator. The stator core supports and protects the three-phase winding of the stator. High-grade silicon steel stamping parts make the stator an iron core. Definition of rotor the rotating part of a motor is called a rotor. The rotor core and rotor winding are part of the rotor. The winding of the rotor is excited by a DC power supply. Squirrel Cage and phase winding are rotor types. The iron core of the squirrel cage rotor is made of cylindrical iron core. The core wire has a semicircular groove on its outer surface, on which a copper or aluminum conductor is placed. With the help of aluminum or copper rings, both ends of the wire are short-circuited. The working stator of the rotor and stator generates a rotating magnetic field due to a three-phase power supply. If the rotor is at rest, the electromagnetic force will be induced in the rotor due to the electromagnetic induction phenomenon. Electromagnetic induction is a phenomenon that induces electromotive force in current-carrying conductor due to variable magnetic field. Current is induced in the rotor, causing the rotor to move. The main difference between stator and rotor stator is the fixed part of the machine, while rotor is the movable part of the machine. The stator core, stator winding and outer frame are the three parts of the stator, while the rotor core and excitation winding are part of the rotor. Three-phase power supply is provided to the stator winding. The rotor is excited by a DC power supply. Compared with the rotor, the winding arrangement of the stator is more complicated. The stator winding is highly insulated because it induces high voltage. The insulation of the rotor is low. Compared with the excitation winding, the stator winding has a larger size and can carry large current. The cooling system of the stator is better than that of the rotor because the stator is fixed. Due to the light weight of the rotor, the friction loss of the rotor is smaller than that of the stator. Conclusion The static part of the motor is a known stator. The rotating part of the machine is called the rotor. The rotor is placed inside the stator core. Three phases are supplied to the stator winding, which generates a rotating magnetic field. The rotor rotates in a rotating magnetic field. Therefore, due to the interaction of the magnetic field between the rotor and the stator, electromotive force is generated. TAG Rotor Stator
