Abstract: The aim of the invention is to achieve a high torque yield in synchronous machines excited by permanent magnets. Said aim is achieved by using subharmonic air gap fields. The rotor comprises an induction cage as well as permanent magnets. The number of winding holes of the stator is greater than q=0.5. The number of poles of the rotor is greater than the base number of poles of the air gap field produced by the windings.

Abstract: Stators for harmonic motors are disclosed. The stators are easy to assemble and include a laminated armature made of sheet metal plates. The laminated armature is formed of a substantially cylindrical laminated star armature with a plurality of radially outwardly oriented pole heads distributed along the circumference of the laminated star armature, and a substantially cylindrical laminated yoke armature having radially inwardly oriented pole teeth and arranged radially outside of and concentrically with the laminated star armature. Each of the pole heads is arranged radially adjacent to a corresponding one of the pole teeth. Windings are applied to the pole teeth before the tooth head sleeve or the laminated star armature are inserted in and joined with th laminated yoke armature.

Abstract: A harmonic motor with an increased slot surface and copper fill factor is described. A laminated stator core for an electric machine, in particular for a synchronous machine, has a substantially cylindrical bore and a plurality of pole teeth extending radially inwardly in the bore. Each of the pole teeth have an inner free end, with a fixed tooth head affixed to the inner end of each second pole tooth, as viewed in the circumferential direction. A pole tooth with a removable head is arranged between each two pool teeth with a fixed tooth head. For easy installation, windings can only be wound around those pole teeth that have a removable tooth head.

Abstract: In a cutting insert, cutting edge (9) is formed by the junction of a chip face (21, 22) and a flank (15). The flank is an extension of a straight portion (11) of a side face (5, 6) which begins at the base (2). Rather than remaining straight throughout the side face, straight portion (11) leads into a transitional face (13) used to form a strip (17), the face of which is the flank (15). Thus, the flank (15) is raised relative to an imaginary lengthening of the side face portion (11).

Abstract: The aim of the invention is to provide a cost-effective, easily regulated rotary-linear drive. Therefore, the invention provides for the rotary-linear drive to connect a rotary drive (10) to a linear drive module (11). The linear drive module (11) comprises a rotatable drive-side receiving device for receiving a torque from the rotary drive (10). Additionally, the linear drive module has a linear motor, the armature (15) of which is rotatable, is rotated by a stator (14), and comprises an output element for the purpose of driving the shaft (12) in a rotary-linear fashion. To this end, the linear drive module (11) also comprises a coupling device (16) that couples the receiving device and the armature (15) in a rotationally secure but not linear fashion.

Abstract: A magnetic radial bearing and a bearing system for supporting a rotating shaft are disclosed. The bearing has a number of electromagnets circumferentially arranged around a rotating shaft. Each of the electromagnets has a coil which is electrically connected so as to generate both a magnetic bias and a rotating three-phase field. First terminals of opposing coils are connected in common to a corresponding phase of a three-phase controller for generating the rotating field, whereas second terminals of the coils not connected to the same phase are connected at corresponding star points. The star points are connected to DC power for generating the magnetic bias.
