This article systematically investigates the field and force modulation effects on magnetic field, radial force, and electromagnetic vibration behaviors of a dual permanent magnet vernier machine (DPMVM). First, the topology and working principle of the DPMVM are analyzed by artfully decoupling it into a permanent magnet (PM) vernier machine (PMVM) and a PM flux reverse machine. Subsequently, the magnetic field modulation effect of DPMVM with a doubly salient pole structure is investigated. The spatial order, speed, and frequency of the abundant magnetic field harmonics affected by rotor modulation (RM) and stator modulation (SM) are summarized. Afterward, the extraordinary behaviors of radial force harmonics and electromagnetic vibration of the DPMVM are studied, in which the magnetic field and force modulation effects are considered. The result shows that the combined effect of field modulation and force modulation is the trigger for the severe vibration of DPMVM. Finally, a prototype of DPMVM is fabricated, and several experiments are conducted to validate the theoretical analysis.
