The transverse flux motor can achieve high force density at low speed. But the special structure also leads to low utilization of PM materials. In this paper, a novel double-side TFLM is proposed and investigated. The permanent magnets mounted on primary side can provide effective flux linkage both in positive and negative operating period. Then, the optimization process is done to achieve sinusoidal back EMF, high force density and low force ripple. Moreover, the electromagnetic performance of the proposed motor is investigated and compared with other linear motors. The results show that the proposed motor is suitable for direct-drive applications.
