Definitions

  • the invention relates to a permanent magnet element as defined in the preamble of claim 1.
  • Permanent magnet elements are used secured to the rotor of permanent magnet machines, such as elec- trie motors and generators, to provide the required magnetic field.
  • the types of permanent magnet elements used in the permanent magnet machines include both ones embedded in the rotor and ones which are surface- mountable onto the periphery.
  • This disclosure relates to surface-mountable permanent magnet elements.
  • the elements should be magnetable without the risk of breakage and, when magnetized, easily mountable onto the peripheral surface of the rotor in files and/or rows.
  • the permanent magnet element should be protected against corrosion as efficiently as possible by coating and encasing against outside air.
  • the element should hold both tangential and radial mechanical stress, which is why the magnets should be locked, in addition to the magnetic grip, in place as reliably as possible, either mechanically only or mechanically and by gluing.
  • a surface-mountable permanent magnet element which is intended to be mounted onto the pe- riphery of the rotor of a permanent magnet machine as the polar element.
  • the permanent magnet element comprises at least one permanent magnet and a protective case enclosing said at least one permanent magnet.
  • the protective case comprises a base plate which comprises a securing member for securing the base plate to the rotor.
  • the base plate comprises a base surface which can be placed against the periphery of the rotor, a top surface on which said at least one permanent magnet is arranged, and at least one lateral surface which extends substantially perpendicularly between the base surface and the top surface.
  • the lateral surface comprises a recess.
  • the protective case further comprises a housing formed from a metal thin sheet material.
  • the housing comprises a top wall which covers the permanent magnet, and a skirt which extends from the top wall over the lateral wall of the base plate.
  • the skirt comprises a joint member, which in the WO- publication is a projection formed from the ' skirt and pressed inside the recess to secure the housing and the base plate to each other in such manner that the joint is within the outer dimensions of the element, which is preferred so that the elements can be disposed in file and/or row as close to each other as possible.
  • the projection which is pressed inside the recess provides stress resistance which is sufficient in many applications for maintaining the coherence of the element .
  • the radial and tangential stresses applied to the permanent magnet element become quite high, even if the rotating speed was relatively low (in the order of 16 to 20 r/min) . In the course of time, this may weaken the coherence, compactness and corrosion resistance of the parts of the element.
  • the air gap between the stationary stator and the rotating rotor is typically in the order of 1 mm, so it is obvious that the joint between the housing and the base plate cannot be allowed to become loose. In requiring high operational reliability with high confidence coefficient, the strength of the joint is a critical factor.
  • the objective of the invention is to eliminate the drawbacks referred to above.
  • the objective of the invention is to disclose a permanent magnet element in which the joint between the housing and the base plate has been further improved.
  • the objective of the invention is to disclose a strong and compact permanent magnet element with good corrosion resistance.
  • the objective of the invention is to disclose a permanent magnet element which is simple in construction, affordable and easily assembled.
  • the permanent magnet element according to the invention is characterized by what has been presented in claim 1.
  • the recess is a groove which extends substantially over the entire length of the lateral surface of the base plate.
  • the joint member is formed by bending the edge of the skirt of the housing inside the groove over a substantial portion of the total length of the skirt.
  • the edge of the skirt of the housing which is bent inside the groove extending substantially over the entire width of the lateral surface and which is almost equal in length locks the housing and the base plate to each other tightly and efficiently in such manner that they are not able to detach from each other during static and dynamic long-term stress.
  • the permanent magnet element is strong, compact, simple in construction, affordable, easily assembled and has good corrosion resistance.
  • the groove is limited by a first planar surface which is disposed at an angle to the lateral surface of the base plate, the first planar surface facing a first direction.
  • the groove is further limited by a second planar surface facing a second direction which is substantially opposite to the first direction.
  • the bending of the skirt inside the groove comprises a first flange which is parallel to the first planar surface and rests against the first planar sur- face.
  • the bending of the skirt inside the groove comprises a second flange which is disposed at an angle to the first flange.
  • the second flange is prefera- bly held in compressive stress against the second planar surface.
  • the free edge of the second flange rests against the second planar surface, further ensuring the strength of the joint.
  • This is preferably provided in such manner that the bending is formed by compressing, i.e. deep drawing, the edge of the skirt inside the groove.
  • the first planar surface and the second planar surface are parallel to each other and spaced at a distance from each other.
  • the first planar surface and the second planar surface are disposed at a right angle to the lateral surface.
  • the groove is rectangular in cross-section. In one embodiment of the permanent magnet element, the first planar surface and the second planar surface are disposed at such angle to the lateral surface that deviates from the right angle. In one embodiment of the permanent magnet element, the groove is a V-groove.
  • the groove is in the form of a parallelogram or trapezoid in cross-section. In one embodiment of the permanent magnet element, the groove is a dovetail.
  • the point of connection of the second planar surface and the lateral surface comprises a formation inside the groove, such as a ridge, protuberance or the like, fitted to ensure that the bending inside the groove stays in the groove.
  • the base plate and the housing are in the form of a parallelepiped.
  • the base plate is rectangular, whereby it comprises four lateral surfaces with the groove formed in each one of them.
  • the skirt of the housing comprises four planar skirt portions wherein the bendings inside the groove are formed.
  • the base plate is made from a ferromagnetic material and the housing is made from a non-magnetic material.
  • FIG. 1 schematically presents a rotor of a permanent magnet machine with a set of permanent magnet elements according to one embodiment of the invention mounted onto the periphery thereof
  • Fig. 2 presents the rotor of Fig. 1 as seen from direction II-II of Fig. 1,
  • Fig. 3 axonometrically presents a permanent magnet element according to one embodiment of the invention as seen from the top, Fig. 4 shows section IV-IV of Fig. 3,
  • Fig. 5 to 7 present a detail of the permanent magnet element according to one embodiment of the invention and steps of bending the skirt bending into the groove by deep drawing, Fig. 8 to 10 present, correspondingly to Fig.

  • Fig. 3 and 4 present one such surface- mountable permanent magnet element 1. It comprises at least one permanent magnet 3 or a number of permanent magnets 3 side by side, and a protective case 4 enclosing the permanent magnet/s 3.
  • the protective case 4 comprises a base plate 5 made from a ferromagnetic material, such as steel, and having on the base a se- curing member 6, shown in Fig. 4, i.e. in this case a closed hole provided with threading, in which a secur- ing bolt can be threaded to secure the base plate to the rotor 2.
  • the base plate comprises a base surface 7 which can be placed against the periphery of the rotor 2.
  • the base plate 5 further comprises a top surface 8 on which the permanent magnet 3 is arranged.
