Abstract: A stator cooling assembly for a linear motor includes a stator and a modular cooling arrangement. The modular cooling arrangement comprises: a U-shaped fluid cooling pipe having first and second linear segments extending along first and second opposite longitudinal sides of the stator; an inlet and outlet port connected to a free end of the first and second linear segments, respectively, for circulating a cooling fluid; a central cooling arrangement comprising primary cooling units mounted into recesses of the stator; and connecting members connecting the central cooling arrangement to the fluid cooling pipe. Each primary cooling unit comprises a heat pipe having first and second portions extending along a recess of the stator and along a portion of the fluid cooling pipe, respectively. The connecting members connect the second portion of the heat pipe of each primary cooling unit to corresponding portions of the fluid cooling pipe.

Abstract: A cooling cage assembly for a rotary electric motor includes a cooling stator arrangement, and a first cylindrical part and a second cylindrical part fixedly mounted against respective opposite sides of the cooling stator arrangement. The cooling stator arrangement includes a stator and cooling tiles mounted against and around the outer circumference of the stator. Each cooling tile includes at least one channel extending from an upper side to a lower side of the cooling tile. The cooling cage assembly further includes a first plurality of fluidic bridges arranged on the upper side of the cooling tiles and a second plurality of fluidic bridges arranged on the lower side of the cooling tiles to form, together with the channel(s) of the cooling tiles, a serpentine flow path, for a cooling fluid, around the outer circumference of the stator.

Abstract: An elastic-locking winding carrier for a preformed coil assembly of a stator of an electric motor, includes a winding portion adapted to receive a winding having a wound electrical conductor to produce a coil. The winding portion includes upper and lower portions, first and second openings arranged on the winding portion, and first and second flexible members located inside respective first and second openings and extending thereacross. The first and second flexible members are arranged such that either of the first and second flexible members cooperates with a tooth of the stator as a function of the magnitude of the gap between the tooth and the lower portion of the winding portion when the preformed coil assembly is mounted on the tooth to fix the preformed coil assembly to the tooth.

Abstract: A support member for a precision device includes a vertical support element and a horizontal support element. The vertical support element extends along a vertical main direction of extent and includes a material with a low thermal expansion coefficient. The horizontal support element horizontally surrounds at least a portion of the vertical support element and is configured to horizontally support the vertical support element against tilting from the main direction of extent. The horizontal support element bounds a thermally insulating interior space in which the vertical support element is partially accommodated.

Abstract: A stator cooling housing for a stator of a rotary electric motor includes a cylindrical frame adapted to be mounted around an iron core and having an outer lateral surface and inlet and outlet channels. A cylindrical jacket is arranged against the outer lateral surface of the cylindrical frame. The cylindrical jacket comprises an inner side having a plurality of cylindrical grooves forming with the outer lateral surface of the cylindrical frame adjacent fluid cooling channels arranged around the cylindrical frame from a frame upper portion to a frame lower portion. Fluid communication portions are arranged such that a cooling fluid is enabled to run from the inlet channel, through the adjacent fluid cooling channels from the frame upper portion to the frame lower portion, and through the outlet channel to form a cooling circuit.

Abstract: A cable shield connecting assembly is arranged to secure and ground a cable to the housing of an electrical device. The cable includes a cable jacket and braided shielding extending from an end portion of the cable jacket. The cable shield connecting assembly includes: a mounting plate having a cavity and an aperture arranged on a bottom side of the cavity; and a grommet having an inner diameter inside which the end portion of the cable jacket is fitted, and upper and lower portions extending on both sides of an edge of the aperture of the mounting plate. The upper portion of the grommet is fitted inside the cavity. The cable shield connecting assembly further includes a clamp pressed-fitted against the upper portion of the grommet inside the cavity to squeeze therebetween the braided shielding.

Abstract: A secondary part of an ironless linear motor includes a spacer and two yoke plates, which are arranged in parallel to each other and carry magnets having an alternating polarity. The yoke plates are maintained at a defined distance by the spacer. The spacer has at least two uninterrupted bore holes. Sleeves having a first screw head and an internal thread are inserted through one of the yoke plates and through a respective uninterrupted bore hole, the first screw heads securing the yoke plate in place on the spacer. A screw, having a second screw head, is screwed through the other yoke plate into each sleeve so that the second screw heads secure the other yoke plate in place on the spacer.
