The stator is the stationary part of a generator that houses the armature windings. It works with the rotating rotor to induce alternating current through electromagnetic induction, converting mechanical energy into electrical energy.
Common materials include electrical steel laminations for the core, copper winding wire, insulation materials, and a structural steel frame. Specific grades and types must be confirmed with the manufacturer.
Relevant standards include IEC 60034-1 for rating and performance, IEC 60034-2-1 for efficiency, IEC 60085 for insulation class, IEC 60034-27-1 for insulation resistance, ISO 10816-1 for vibration, and IEC 60034-6 for cooling. These are references for verification, not proof of compliance.
Check the rated power, voltage, speed, efficiency, insulation class, temperature rise, and other parameters against your requirements. Always consult the legal manufacturer or supplier to confirm model-specific values and compliance with applicable standards.
