    Abstract: A bobbin structure of an armature of a three-phase motor having 6N (N is a natural number) slots and 3N coils per phase, the bobbin structure including: a main pole into which a winding bobbin around which a coil is wound is inserted; and an auxiliary pole into which an empty bobbin around which the coil is not wound is inserted. The main pole and the auxiliary pole are placed in a circumferential direction with respect to a rotation axis, and a contact portion where the empty bobbin and the winding bobbin are in contact with each other is formed on each of an outer peripheral side and an inner peripheral side of the slot formed between the main pole and the auxiliary pole.

    Abstract: There is provided an electromagnetic solenoid including: a stator including a stator core; a coil configured to generate an electromagnetic attractive force by energizing the stator core; a mover configured to be attracted toward the stator by the electromagnetic attractive force; and a magnetic elastic admixture including a resin material with soft magnetism and elasticity, wherein the mover is configured to be capable of reciprocating by being released by an elastic body that generates a biasing force in a direction opposite to a direction in which the electromagnetic attractive force acts, a proximal end of the mover is located at a first proximal end position upon the mover being electromagnetically attracted toward the stator during energization of the coil, and is located at a second proximal end position upon the mover being electromagnetically released and moved to a side opposite to the stator during de-energization of the coil, and the magnetic elastic admixture is configured to elastically deform between the mover and the stator and not to be separated from a contact surface with the mover and a contact surface with the stator.
