Abstract:
1. A motor comprising: a first segment core having a first leg section and a first semicircular-arc teeth section; a second segment core having a second leg section and a second semicircular-arc teeth section; a plate body that bridges a slot open section and is stacked on the first segment core and the second segment core, the slot open section being formed by arranging the first leg section of the first segment core and the second leg section of the second segment core in the same direction and by closely facing both tips of the teeth section of the first segment core to both tips of the teeth section of the second segment core; a third segment core, a first end of the third segment core being bound to the first leg section of the first segment core, a second end of the third segment core being bound to the second leg section of the second segment core; an exciting section formed of a coil bobbin and a winding, the coil bobbin using the third segment core as a magnetic core; a rotor disposed in a rotor insertion hole formed in a facing section of the teeth sections; and a pair of bearing units for supporting an output shaft penetrating the rotor, wherein a main core formed of the plate body, the first segment core, and the second segment core is sandwiched between the pair of bearing units, wherein the motor has a circuit wiring board for electrically inter-coupling the winding of the exciting section and a power supply connecting body, and wherein at least a part of the exciting section, the circuit wiring board, and a part of the power supply connecting body are covered with a resin molded body.
