An electric permanent magnet chuck, comprising a casing (1), the casing being provided thereon with at least one open inner cavity; reversible magnetic material (2) is provided at a lower portion of the inner cavity, and a coil (3) is arranged in the inner cavity along an outer wall of the reversible magnetic material; a magnetic pole (4) is superposed and fixed in the inner cavity, an annular groove being provided at a lower surface of the magnetic pole, and permanent magnetic material (5) that matches the annular groove being disposed in the annular groove. The electric permanent magnet chuck has the advantages of a simple structure, low processing difficulty, good sealing performance, small magnetic loss and so on.

An electronic actuator for an elevator safety brake system, the actuator having: an electromagnet assembly; and a first magnet assembly configured for being retracted from engagement with a rail depending on an energized state of the electromagnet assembly, the first magnet assembly including: blocks spaced apart from each other, respectively defining block bodies, and elongated block legs respectively extending aft from the block bodies; and a first magnet is disposed between the block bodies; wherein the electromagnet assembly includes: a core that defines: a core body extending between core ends that are spaced apart from each other; and core stub legs respectively extending forward from the core ends that are positioned adjacent to the elongated block legs when the first magnet assembly is retracted; and a coil winding wound about bobbins that are placed over the core body, the elongated block legs are longer than the core stub legs.

The invention relates to a unitary magnet (1) that has an elongate shape and an at least partially ovoid contour as the unitary magnet (1) comprises a first portion (1a) forming a body of the unitary magnet (1) that has a larger cross-section and extends over a greater portion of the length of the unitary magnet (1) than at least one second longitudinal end portion (1b) that points towards an associated longitudinal end of the magnet and has a decreasing cross-section towards the longitudinal end.

A permanent magnet electric motor for a vehicle comprises a stator comprising a round wire defining N portions and a stator lamination defining an inner surface, N slots, and N/2 alternating, full-slot-width apertures in the inner surface, wherein the N portions of the round wire are disposed in the N slots, respectively, and a rotor comprising M permanent magnet assemblies defining M respective poles, each of the M permanent magnet assemblies comprising a pair or bar magnets arranged in a V-shaped configuration with respect to each other, wherein N equals 6 and M equals 4 or N and M equal respective double multiples thereof, and a rotor lamination having the M permanent magnet assembles disposed therein and defining, for each of the M permanent magnet assemblies, at least three sets of air pockets disposed proximate to the respective permanent magnet assembly.

A magnetic closure device has two complementary magnetic closure elements. Each of the two complementary magnetic closure elements includes an elongated magnet carrier having a single direction of main extension, and a plurality of permanent magnets supported by the magnet carrier in defined positions along the direction of main extension. Each of the permanent magnets is permanently magnetized either longitudinally or diametrically with regard to the direction of main extension. The permanent magnets following to each other in the direction of main extension are arranged in a closure alignment pattern having a magnetic non-repetition length extending over three or more of the permanent magnets. The magnet carrier is bendable in at least one direction orthogonal to the direction of main extension.

A magnetic toy construction block includes an inner shell and an outer shell which are arranged to form a module having a shell-within-a-shell construction. Disc-shaped magnets are rotatably received and maintained in pockets formed in the inner shell of the module. The inner shell is permanently housed within the outer shell such that the magnets lie in close proximity to its sidewalls and hence sidewalls of the module itself.

A magnet structure is a magnet structure for a TMR element which is an MR element. The magnet structure includes a bonded magnet compact that has a first main surface facing the TMR element, and a second main surface on a side opposite to the first main surface; and a tubular member that supports the bonded magnet compact. The bonded magnet compact has a gate portion which is provided on the second main surface and includes a gate mark formed by performing injection molding. The gate portion is provided at a position overlapping a center on the second main surface when seen from the second main surface side.
