Rotor assembly is a moving part of an electromagnetic system which is used in an electric motor, generator, or alternator. It rotates as a result of the interplay of magnetic fields and windings, which creates a torque around the rotor's axis. This component has permanent magnets that rotate around the iron plates of the stator to produce alternating current. The rotor assembly is a coil attached on an axle, generates the mechanical energy required for rotation. It is a shaft with mounted impellers, sleeves, sealants, a thrust disc, and a coupling hub. This product is attached at the nondriven end of the shaft can all securely transfer torque via it.
