Due to simpler mechanical structure and magnetic gearing effects, Permanent Magnet Vernier Machines (PMVMs) attract researcher interest because of their higher torque density for direct drive applications. However, regular PMVMs utilize more rare earth Permanent Magnet (PM), which increases machine cost and weight. Moreover, the PMs are mounted on the rotor surface, which enhances flux leakage and flux circulation, which degrade electromagnetic performance that ultimately decreases average torque, torque density, power density and efficiency. A new Split Pole PMVM (SP-PMVM) with Halbach PM arrangement in the stator slot opening and consequent pole rotor is proposed to overcome the issues above. The proposed SP-PMVM enhanced flux modulation phenomena to improve electromagnetic performance. Comparing the proposed machine with the existing designs reveals that the proposed design reduces the PM utilization by 22.2&#x0025; and improves the flux linkage by 41.3&#x0025; due to suppression of leakage flux and flux circulation. Moreover, the average torque is boosted by 42.35&#x0025;. Furthermore, torque and power densities are increased by 83.01&#x0025; and 44.84&#x0025;, respectively. In addition, in comparison with the existing conventional design, the efficiency of the proposed model is enhanced by 25.01&#x0025; at the cost of 19.75&#x0025; cogging torque.
