In SU(3)LXU(1)N gauge models for electroweak interactions, we discuss how to implement a radiative mechanism of generating Majorana neutrino masses by considering the property that the Higgs scalar, which has a coupling to a charged lepton ()-neutrino () pair, is naturally included. The mechanism is shown to work in models with a heavy charged lepton, , in a lepton triplet (, , ) and with a heavy neutral lepton, N, in (, , N). A minimal model with and in (, , ) together with a sextet Higgs scalar suffers from a fine-tuning problem to suppress tree-level neutrino masses.
