335312 Motor and Generator Manufacturing

This U.S. industry comprises establishments primarily engaged in manufacturing electric motors (except internal combustion engine starting motors), power generators (except battery charging alternators for internal combustion engines), and motor generator sets (except turbine generator set units). This industry includes establishments rewinding armatures on a factory basis.

Cross-References. Establishments primarily engaged in--
  • Manufacturing electric outboard motors--are classified in U.S. Industry 333618, Other Engine Equipment Manufacturing;
  • Manufacturing gas, steam, or hydraulic turbine generator set units--are classified in U.S. Industry 333611, Turbine and Turbine Generator Set Units Manufacturing;
  • Manufacturing starting motors and battery charging alternators for internal combustion engines--are classified in Industry 336320, Motor Vehicle Electrical and Electronic Equipment Manufacturing;
  • Rewinding armatures, not on a factory basis--are classified in Industry 811310, Commercial and Industrial Machinery and Equipment (except Automotive and Electronic) Repair and Maintenance; and
  • Manufacturing welding and soldering equipment (except handheld soldering irons)--are classified in U.S. Industry 333992, Welding and Soldering Equipment Manufacturing.
