Fast and accurate transient response is the main requirement in electric machine position control. Conventional cascade control structure has sluggish response due to the limitation of inner control loop bandwidth. In this paper, in order to decrease the Permanent Magnet Synchronous Motor (PMSM) transient response time it can be used reference model using feed-forward signals. In this structure...

Permanent magnet linear alternators are energy converting devices that have been under research and development for years. This type of alternators have advantages of high efficiency and no need of liner motion to rotation converting, when the driving force is in linear oscillation. Such applications can be found when ocean tide, solar power, and swing motions are used for generating electric p...

The paper presents a detailed calculation of characteristic of five different topology permanent magnet machines for high performance traction including hybrid -electric vehicles using finite element analysis (FEA) method. These machines include V-shape single layer interior PM, W-shape single-layer interior PM, Segment interior PM and surface PM on the rotor and with distributed winding on the...

In this paper, one of the main cogging torque minimization methods, magnet skew, is examined in detail for Axial Flux Permanent Magnet (AFPM) disc motor. Various magnet skewing methods, types, and effects on the machine performance are also investigated using 3D Finite Element Analysis. The results are compared with a reference AFPM motor, and the improvements on cogging torque component are de...

The unique merits of internal permanent magnet synchronous machine (IPMSM) make it a good candidate for automotive industrial applications. This paper presents the design of an internal permanent magnet synchronous machine having fractional slot configuration with single layer concentrated winding arrangement. The electromagnetic analysis has been performed using finite element analysis via ANS...

This paper studies the use of the PMSM (permanent magnet synchronous machine) generators instead of the induction based alternating current generators in renewable energy sources (wind turbines, combined heat and power, etc.). The paper considers the most significant advantages of the novel permanent magnet technology such as increased specific power, high torque, reduced maintenance costs, inc...
