Normal force and vibration investigation of linear permanent-magnet vernier machine

Normal force is the dominant source of vibration in the linear permanent-magnet (LPM) machine. In order to investigate vibration of a new LPM vernier machine, normal pressure and their spatial harmonics are calculated by finite element method. Then, the natural vibration modes and transient displace...

Summary:Normal force is the dominant source of vibration in the linear permanent-magnet (LPM) machine. In order to investigate vibration of a new LPM vernier machine, normal pressure and their spatial harmonics are calculated by finite element method. Then, the natural vibration modes and transient displacement of the short mover is predicted. Finally, experimental result is given for verification. Results are instructive for design of a high precision and low vibration LPM machine.
