Abstract
A light-weight and small-size electric motor in which linear movement can be obtained without requiring any special movement conversion mechanism. The electric motor includes a rotor (4), a rotary shaft (5, 6, 5a) coupled to the rotor (4), and a screw mechanism (7) for Supporting the rotary shaft (5, 6, 5a), the screw mechanism (7) being configured such that the rotor (4) is moved in an axial direction of the rotary shaft (5, 6, 5a) by movement of the rotary shaft (5, 6, 5a) within the screw mechanism (7) upon rotation of the rotor (4).
Claims16
An electric motor comprising:
- a housing:
- a rotor accommodated in the housing;
- a rotary shaft fixed on the rotor and having a male screw;
- and
- a female screw mechanism affixed to the housing and engageable with the male screw of the rotary shaft;
