The work presents starting, steady-state modelling and simulation studies of single-phase transfer field reluctance motor operating in the asynchronous mode from which the performance indices could be predicted. The machine is made up of two similar motors that are integrally wound and mechanically coupled together, but with their pole axes 0.5 degree out of phase in space. The transfer field machine in general is a low speed machine operating at half the synchronous speed of a normal induction machine. The equivalent circuit of the machine is derived using d-q-o transformation fundamentals. The speed range of the machine unlike the normal induction machine counterpart with slip range 0 < s < 2, has a corresponding slip range 0.5 < s < 1.5. The simulation results reveal a good similarity in its steady state characteristics with that of the existing normal single phase induction motor counterpart. Obviously, all single phase asynchronous motors are not self starting. They suffer the severe problem of getting the rotor rotate when started. The designed value of capacitor necessary for satisfactory starting performance of the machine is also discussed. Due to its inherent half speed characteristics, the possible areas of application are limited and are also suggested in the work.
