Abstract -This paper treats a novel linear hybrid motor (LHM) by both induction and synchronous operations. The proposed motor consists of one pair of linear synchronous motors (LSMs) and a linear induction motor (LIM). The primary-cores of both LSM and LIM have a common ring winding, and the secondary solid-conductor is arranged in both LIM and the interpole space of LSM. The feature of the motor is that the undesirable vertical force in LSM is offset by the symmetrical double-sided construction and the secondary is capable of selfstarting by induction operation. From the investigation by the three-dimensional finite element analysis and experiment, we derive an optimal exciting condition for starting, and then verify that the proposed LHM is effective for practical use.
