Direct drive applications have become one of the most exciting research fields recently. Using the modulation effect (already known as the gearing effect), these kinds of machines can work at low speeds and have the low volume at the same time. Permanent magnet Vernier machine (PMVM) is one of these machines which have been the topic of papers during recent years. In order to reducing the quantity of PM material and hence cost, the Consequent pole permanent magnet (CPPM) machine has been proposed. This is why, in this paper, three different proposed structures of VPMs with surface-mounted permanent magnet Vernier (SPMV) machine, consequent pole with the same PM pole and iron pole shapes (CPPMV I) and consequent pole with the different PM pole and iron pole shapes (CPPMV II) are analyzed. First, the structures and operating principles will be explained. Second, all three machines will be designed in the same condition but with different magnet volumes and finally, cogging torque, airgap flux density harmonics and load torque of all machines will be studied. Under the same operation condition, the CPPMV II showed better performance compared with the other ones.
