A novel hybrid linear reluctance motor with series magnetic circuit was presented in this paper. On the basis of the analysis of the magnetic circuit of the motor and using the method of linear analyzing, the thrust characteristic was obtained. Experiments for the prototype indicate that the novel linear motor has bigger thrust force per volume. Further more through optimizing design of the electromagnetic parameter and structural parameter, the motor can obtain higher output trust, lower volume and weight and faster system response characteristic.
