Permanent magnet synchronous motor thermal analysis

6th IET International Conference on Power Electronics, Machines and Drives (PEMD 2012), 2012
Permanent magnet synchronous motors (PMSM) are used in a great variety of applications such as: electric toys, electric tools, medical/chemical industries, centrifuges at high speed, vehicle applications (motor starters), robot applications etc. All these have in common small size, high energy density, increased torque for a large speed range, high ...

Permanent magnet excited synchronous motors

Electrical Engineering, 1955
FRACTIONAL-HORSEPOWER synchronous motors are generally available for quantity production in only the reluctance or hysteresis types. The reasons for this are: the simplicity of their rotor constructions, because of the omission of d-c excitation; and the possibility of assembling the rotors of either type in standard induction motor frames ...

Sensorless permanent magnet synchronous motor drives

CCECE '97. Canadian Conference on Electrical and Computer Engineering. Engineering Innovation: Voyage of Discovery. Conference Proceedings, 2002
Permanent magnet (PM) synchronous motors are gaining wide recognition over other types of motors in drive systems, mainly due to their inherently advantageous features. For successful operation of PM motor drives, position and speed sensing are of critical importance.

Five-Phase Permanent-Magnet Synchronous Motor

IEEE Latin America Transactions, 2017
This paper presents the mathematical model of a five phase interior permanent magnet synchronous motor (5IPMSM) with sinusoidal back electromotive force in abcde frame. The 5 phase reference frame is transformed into two fictitious orthogonal sets termed as dq and x1y10 reference frame. Also, the develop torque is obtained in dq reference frame.

The Study of Permanent Magnet Demagnetization in Permanent Magnet Synchronous Motor

2021 IEEE International Conference on Advances in Electrical Engineering and Computer Applications (AEECA), 2021
Permanent magnet demagnetization is one of the common faults of permanent magnet synchronous motor, which seriously threatens the safe and reliable operation of the motor and reduces the service life of the motor. Based on the principle of permanent magnet demagnetization, this paper analyzes the causes of irreversible permanent magnet demagnetization.

Modelling of permanent magnet synchronous motors

IEEE Transactions on Magnetics, 1986
A permanent magnet motor with power semiconductor supply and shaft position sensing can be constructed using radially- directed high energy magnets on its rotor. This paper presents equivalent circuit models for such motors. The model parameters are related to the motor structure and dimensions.

Permanent magnet synchronous motor drives

2015
The aim of the chapter is to enable the power electronics community to address emerging (but proven) topics in electrical drives, with special emphasis on permanent magnet synchronous motor (PMSM) drives. Among the many alternatives, the collected material was classified according to the type of control, further detailed when necessary for the specific

Chaos Synchronization Analysis on Permanent Magnet Synchronous Motor

2015 International Conference on Industrial Informatics - Computing Technology, Intelligent Technology, Industrial Information Integration, 2015
This paper deals with different chaos synchronization control of Permanent Magnet Synchronous Motor (PMSM). Based on the theory of finite-time stability theory, a novel controller is designed to control the PMSM. In addition, another kind of controller for the PMSM with uncertain parameters is designed to achieve global asymptotic synchronization goal -

Transient analysis of permanent magnet linear synchronous motors

2005 European Conference on Power Electronics and Applications, 2005
A modified one-dimensional mathematical model based on the space-vectors theory is used to analyse the performance of permanent magnet linear synchronous motors with starting and dumping sheet. The end-effects are taken into account by assuming that the length of the iron core is infinite and the length of the armature winding is finite.
