General Electric 5BC46AB1581B is a double-shaft tachometer generator rated for 100 VDC and 1000 RPM. As a tachometer generator, it produces an electrical output tied to shaft speed in rotating equipment, enabling speed monitoring and feedback in appropriate systems. The part number 5BC46AB1581B identifies this unit, and the dual-shaft design accommodates connections to two shafts or to drive and sensing paths in installations where a DC tachometer signal is required. This configuration and rating specify its use in equipment that relies on a 100 VDC, 1000 RPM tachometer output for speed reference or control purposes.
