Design Considerations and Validation of Permanent Magnet Vernier Machine with Consequent Pole Rotor for Low Speed Servo Applications

Abstract

-This paper deals with design consideration and validation of a new pole-slot combination for permanent magnet vernier machine (PMVM) with consequent pole (CP) rotor especially for extremely low speed servo applications. A 136pole-24slot PMVM with CP rotor is introduced and analyzed by 2D and 3D finite element analysis (FEA) and discussion on experimental validation is also included.

Development of a 20-Pole–24-Slot SPMSM With Consequent Pole Rotor for In-Wheel Direct Drive

“…In other words, this topology can serve as a cost-effective solution when considering manufacturing. The rotor structure that are similar to the proposed one in this paper can be found in [29]- [37]. The proposed motor also belongs to a family of doubly salient PM motors and it is known that this kind of motors exhibit magnetic saliency and consequently increase reluctance torque and field weakening operation region.…”

Development and Testing of a Novel Cylindrical Permanent Magnet Linear Generator

“…They may still prove favourable for long stroke machines with an over length translator [6]. Vernier Hybrid Machines (VHMs) have both the PMs and the coils mounted in the stator and have been developed for low-speed high torque directdrive applications, either in rotary [7][8][9] or linear versions [10,11]. Initially, they were also called Flux Reversal Machines due to the nature of their electromagnetic flux production [12,13].…”

Development of a double-sided consequent pole linear vernier hybrid permanent-magnet machine for wave energy converters

“…The consequent pole technique is adopted in the new design which halves the amount of the PM material leading to a significant reduction in the initial cost of the generator. The performance of the machine would not be sacrificed by implementing this topology [14]. This class of machine can offer higher average force, higher no-load back EMF, while it exhibits lower cogging force and force ripple compared to that of the baseline LVHPM machine.…”
