A reciprocating electric motor includes a housing, a stator member disposed in the housing, a reciprocating armature movable relative to the housing, and. controller. The stator member includes first and second. electromagnet units opposite to each other in a longitudinal direction of the housing. The reciprocating armature includes first and second. elongated pole units each of which is moved into register with a corresponding one of the first and second electromagnet units when the corresponding one of the first and second electromagnet units is energized. The controller is configured to alternately energize the first and second electromagnet units to cause reciprocating movement of the reciprocating armature. |
