Hybrid permanent-magnet synchronous motor.
IEEJ Transactions on Industry Applications, 1990A number of configurations for interior permanent-magnet type synchronous motors have been developed in recent years. This paper describes a form of motor having large output and high efficiency. Use can be made of samarium cobalt magnets, and the volume of the magnets used in the rotor is small compared with that of the conventional permanent-magnet ...

Induction versus permanent magnet motors
IEEE Industry Applications Magazine, 2009It is clear that a premium will continue to be placed on energy efficiency in motors. The circumstances around global warming and the availability of future oil supplies only increase the focus on electric motors as key elements in the efficient utilization of energy resources. PMs offer an important tool in the quest for cost-effective ways to further

Permanent magnet excited synchronous motors
Electrical Engineering, 1955FRACTIONAL-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 ...

Permanent magnet synchronous motor drives
2015The 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

PERMANENT-MAGNETICALLY EXCITED ELECTRICAL MOTOR
2004Disclosed is a permanent-magnetically excited electrical motor comprising a stator part (2), a rotor part (30) movable in relation to the stator part (2), and an air gap (8) between the stator part (2) and the rotor part (30). Either the stator part (2) or the rotor part (30) is provided with a flow path assembly for magnetic flow and coils (6), and ...

Permanent-Magnet DC Linear Motors
1996Abstract No standard work of reference, dealing with dc linear motor in all its aspects has ever been published. However, a considerable amount of literature in the form of published papers dealing with this subject, and also an amount of hitherto unpublished work, particularly of an industrial or applied nature, has been accumulated ...
