This paper proposes a back electromotive force estimation error compensation method for accurate rotor position estimation of surface mounted permanent magnet synchronous motors. When estimating the rotor position of surface mounted permanent magnet synchronous motor sensorless drives, a direct current offset error component occurs in the voltage sensor. As a result, the rotor position is disto...

in the permanent magnet linear synchronous motor (pmlsm), force ripple is harmful, useless and disturbing. the force ripple is basically composed of two components: detent force and mutual force ripple. this force is influenced by the geometric parameters of the permanent magnet (pm) motors; such as width, thickness and length of the magnet poles, length and thickness of the rotor and stator, a...

Combining the main advantages of the permanent magnet synchronous motors and pure synchronous reluctance motors (SynRM), permanent magnet assisted synchronous reluctance motor (PMaSynRM) has been considered as a promising alternative to the conventional induction motors. In this paper, utilizing a macroscopic design parameter, called insulation ratio along the q-axis, and based on the magnetic ...

This article presents a performance comparison of an interior mounted permanent magnet synchronous generator (IPMSG) with a synchronous reluctance generator (SynRG) with the same size for a wind application. It is found that using the same geometrical dimensions, a SynRG can convert 74 % of the power that an IPMSG can convert, while it has 80% of the IPMSG weight. Moreover it is found that the ...

Permanent Magnet Synchronous Motor (PMSM) variable-speed drive is widely used in the industry because of its particularly high mechanical power density, simplicity and cost effectiveness. Eliminating the mechanical sensor mounted on the shaft of the motors gives further improvement. These drives are referred to as “sensorless” electrical drives. In this paper a novel sensorless algorithm is pro...

During a long time, permanent magnet synchronous motor (PMSM) were only reserved for some specific applications, however, recently, these machines are becoming more used due to the powerful magnetic characteristic of the rare earth, being used in different areas. Several researchers have proposed implementations combining the use of permanent magnet synchronous motor with the direct torque cont...

In a permanent magnet synchronous motor where inductances vary as a function of rotor angle, the 2 phase (d-q) equivalent circuit model is commonly used for simplicity and intuition. In this article, a two phase model for a PM synchronous motor is derived and the properties of the circuits and variables are discussed in relation to the physical 3 phase entities. Moreover, the paper suggests met...
