Motor device

A motor device comprises a base, an iron core, a coil, a reciprocating motion assembly, a magnet set and an output part, and the iron core is provided with at least one magnetic shoe part; the coil is arranged on the magnetic shoe part; the reciprocating motion assembly comprises a first motion group, a second motion group and an elastic reset part, and the first motion group and the second motion group can reciprocate in opposite directions in a first direction X; the elastic reset part is connected between the first motion group and the second motion group and used for driving the first motion group and the second motion group to reset; the magnet group is fixedly arranged on the reciprocating motion assembly and is spaced from the end part of the magnetic shoe part; the output part is fixedly arranged on the reciprocating motion assembly; when a working current is introduced into the coil, the magnetic shoe part generates virtual magnetic poles with alternately changed polarities and interacts with the mag
