Rotex Tachogenerators have been manufactured in Italy by Rotex Ellettromeccanica since the mid 80’s.
The ROTEX D.C. tachogenerators are produced with simple but advanced constructive technologies which, together with an accurate construction, an electrical and mechanical testing with strict quality controls, ensure that the ROTEX D.C. tachogenerators maintain their characteristics constant during time. The special magnetic structure, the large quantity of slots in the rotor and the high number of commutator segments provide an excellent output signal suitable in all those cases where a good linearity between voltaqe and rotation speed over all the operation range is essential. The ROTEX D.C. tachogenerators are available in several different versions, either with flanges and shaft: series FD-FM, or with hallow shaft: series DD-MD-SD
