Steady – State Performance of Induction and Transfer Field Motors – A Comparison
Abstract
This paper presents the steady–state performance comparison between polyphase induction motor and polyphase TF motor operating in the asynchronous mode. It is shown graphically that a p-pole TF motor in operation is similar to an induction motor with 2p poles and hence its synchronous speed is limited to one-half (ω/2) of that of an induction motor. Additionally the pull-out torque of TF motor is inferior to that of an induction motor of the same dimensions, being less than ¼ of that of an equivalent induction motor on account of its higher leakage reqactance and in particular, the quadrature axis reactance.
