Hi Greg,

The P/N for the fan motor in the 8640B manual (TM 9-4935-601-14-7&P) shows it to be 1AD3001-OA.

Thanks,
Barry - N4BUQ

Barry,

The fan in the HP 8640B is a simple 2-terminal DC motor. The Siemens device
is a 13-terminal brushless Hall Effect motor that requires external
excitation from a more elaborate switching driver scheme.
