The rotor/stator assembly is the core electromagnetic part of an electric motor. It converts electrical energy into mechanical rotation by generating torque through the interaction of magnetic fields.
Typical materials include electrical steel (silicon steel) for laminations, copper for windings, permanent magnets (e.g., neodymium) for the rotor, and aluminum for the rotor cage in induction motors.
For industrial motors, rated power ranges from 0.75 to 250 kW, and rated voltage from 220 to 690 V AC, per IEC 60034-1. Frequency is typically 50 or 60 Hz.
Check the balance grade (ISO 21940-11), concentricity (ISO 1101), insulation class (IEC 60085), efficiency class (IEC 60034-30-1), and IP rating (IEC 60529). Always confirm model-specific values with the manufacturer.
