摘要： An electrical motor or generator comprises a rotor 79 without windings, a stator 78 having armature windings comprising at least two coils A1, A2 having active portions positioned within armature winding slots 81 in a stator iron, and field windings F having active portions positioned within field winding slots 80 in the stator iron. An electronic control circuit is provided for controlling the currents in the coils A1, A2 in synchronism with rotation of the rotor such that periods in which a magnetomotive force is generated in one direction by current flow in one of the coils alternate with periods in which a magnetomotive force is generated in the opposite direction by current flow in another of the coils. The armature winding slots and the field winding slots are equal in number and alternate with one another in the stator iron. Furthermore, considering the width of each slot 80, 81 as being the maximum extent of the slot in the direction of rotation of the rotor and considering the depth of each slot as being the maximum extent of the slot radially of the rotor and the thickness of the back iron behind the slot as being the distance between the maximum extent of the slot and the maximum extent of the armature iron along the same radial direction, the width of each armature slot 81 is greater than the width of each field winding slot 80 and the thickness of the back iron behind each armature winding slot 81 is greater than the thickness of the back iron behind each field winding slot 80. Such an arrangement optimises the power efficiency whilst making best use of the magnetic material.

摘要： A mangle magnetic structure is composed of a plurality of transversely magnetized parallel cylindrical rods forming a cylindrical shell defining an interior cavity filled with insulated wires in parallel to the mangle's principal axis. Two semicircular sections composed of the solid copper wires, within the interior cavity, are physically separated and insulated from each other by a barrier. The transversely magnetized parallel cylindrical rods are rotatable around each rod's individual axis, causing an interior magnetic field within interior cavity and the semicircular sections. The transversely magnetized parallel cylindrical rods are rotated so that the lines of force emanating from them produce an Alternating Current axial electromotive force to drive current through the semicircular sections and to an external load. In one embodiment, two sets of concentric transversely magnetized parallel cylindrical rods form the magnetic shell.

摘要： A work unit for automatic machine tools is provided with a spindle that moves in translation and rotates with respect to a work axis. The spindle is housed within a sleeve that is slidable along the work axis, with the spindle being rotatable within. Rotation of the spindle is controlled by a drive unit mounted directly on the spindle and arranged inside the sleeve, which eliminates the need for a separate transmission mechanism and thereby results in a simplified construction of the work unit and an increase in performance.

The width E of the minimum air-gap between teeth of the rotor and of the stator as measured in the direction perpendicular to the degree of freedom is approximately equal to or greater than 0.7 &mgr;0Umax/J where &mgr;0 is the permeability of free space, Umax is the maximum generated magnetic potential difference for causing the magnetic field to pass through the air-gap E, and where J is the maximum polarization of the soft magnetic material used for making the teeth.

摘要： This switched reluctance machine has at least six magnet yokes (11) on the stator side. The yokes are placed circularly and they carry windings (112). These yokes (11) can be placed at the inner side and/or the outer side of the rotor (12). These yokes which are magnetically insulated to each other interact with the salient poles (121) of the rotor (12). The two phases (X, Y) of this machine are push-pull controlled by a Hall sensor (31). This way the electronic circuitry becomes very simple.
