STEPPING MOTOR
PURPOSE:To reduce the size and to increase the torque of a stepping motor by bending a magnetic plate made of a plurality of legs extending radially from an annular base from the outside to form a core. CONSTITUTION:An A-phase stator is formed of a core body made of cores 23, 24 and a coil 25. A B-p...

| Zusammenfassung: | PURPOSE:To reduce the size and to increase the torque of a stepping motor by bending a magnetic plate made of a plurality of legs extending radially from an annular base from the outside to form a core. CONSTITUTION:An A-phase stator is formed of a core body made of cores 23, 24 and a coil 25. A B-phase stator is formed of a core body made of cores 26, 27 and a coil 28. Cores 23, 24, 26, 27 are formed by bending a magnetic plate made of an annular base formed by punching and legs extending radially at an equal interval perpendicularly to the legs with respect to the base in a cup shape. The cores 23, 24, 26, 27 are concentrically disposed to form A-phase and B-phase core bodies to mount coils 25, 26 to form A-phase and B-phase stators. |
