  • Publication number: 20210021162
    Abstract: Provided is a stator core formed by laminating electrical steel sheets to steadily curtail iron loss and a motor equipped with the stator core. A stator core 10 formed by laminating electrical steel sheets 11 having a thickness of from 25 to 80 ?m steadily curtails iron loss. A motor 20 including the stator core 10 formed by laminating electrical steel sheets 11 having a thickness of from 25 to 80 ?m has a steadily improved efficiency.

  • Patent number: 9567303
    Abstract: Provided is a method for producing 5-hydroxy-1H-imidazole-4-carboxamide.3/4 hydrate, including: reacting 2-aminomalonamide with a compound represented by the following formula [1] in the presence of a carboxylic acid to obtain 5-hydroxy-1H-imidazole-4-carboxamide: wherein, in formula [1], each R independently represents a C1-3 alkyl group; reacting the resulting 5-hydroxy-1H-imidazole-4-carboxamide with an acidic compound to obtain a 5-hydroxy-1H-imidazole-4-carboxamide acid salt or a hydrate thereof; and reacting the resulting 5-hydroxy-1H-imidazole-4-carboxamide acid salt or hydrate thereof with a salt in the presence of an acidic solvent to obtain the 5-hydroxy-1H-imidazole-4-carboxamide.3/4 hydrate.

  • Patent number: 8936211
    Abstract: A method of manufacturing a stator includes a first winding step of, with annular conductors of a first coil portion being placed in a coil holding unit, inserting the annular conductors into the respective slots by a coil pushing-out unit; and a second winding step of, after the first coil winding step, with annular conductors of a second coil portion placed in the coil holding unit, moving a positioning unit in an axial direction at least from one end of the stator core to the other end of the stator core in the axial direction, and inserting the annular conductors into the respective slots by the coil pushing-out unit while a part of the first coil portion, which is located in the slots, is pressed in a direction from the opening of the slot toward an inside of the slot by the radial end faces of the projecting teeth.
