It is pointed out that a new mode of permanent magnet excitation consisting of segments magnetized nonradially, with different directions of magnetization, produces quite new solutions to the critical problems of permanent magnet excited electrical machines. The authors derive analytical formulae to calcu...
to exhibit magnetism. for example, permanent magnets are used as compass needles. example of permanent magnets an everyday example of a permanent magnet is a refrigerator magnet. the image below shows the magnetic field produced by a bar magnet. the magnetic field is the sphere of influence of...
An electrical machine, particularly a permanent magnet motor, having a number of poles and teeth or tooth groups that is divisible by a whole number A around which coil-forming loops of winding wire are arranged such that B coils are arranged in series, the coils having a number of windings...
The electric or electromotive force (EMF) balance equation for a Permanent Magnet Synchronous Motor (PMSM) is a fundamental relationship that describes the voltage, current, and flux linkage in the stator windings. 永磁同步电机(PMSM)的电动势(EMF)平衡方程式是描述定子绕组中的电压、电流和磁通关系的基...
a magnet motor used from a low output region including a no-load region to a high output region, the steel sheet enabling a no-load loss and a loss when being rotated by external force to be reduced, and to provide a permanent magnet motor obtained by using the electrical steel sheet....
German Patent DE19525346 Kind Code: A1 Abstract: The synchronous machine has a modular construction provided by a number of axially stacked discs (1), each having a permanent magnet rotor and a stator with a pair of stator cores (6a,6b) and a multi-strand annular winding (7), formed from...
