Abstract
A stepping motor includes a bracket, a housing having a first end coupled to the bracket and a second end having a reduced width compared with the first end, a stator disposed in the housing to form electric field, a first supporting unit formed on a first end of the bracket, a magnet fixed corresponding to the stator to provide the electric field, a second supporting unit supported on the second end of the housing, a rotor supported by the first and second supporting units, and a stopper fitted on an opened end of the second end of the housing to support the second supporting unit.
Claims29
A stepping motor comprising:
- a bracket;
- a housing having a first end coupled to the bracket and a second end having a reduced width compared with the first end;
- a stator disposed in the housing to form electric field;
- a first supporting unit formed on a first end of the bracket;
- a magnet fixed corresponding to the stator to provide the magnetic field;
- a second supporting unit supported on the second end of the housing;
- a rotor supported by the first and second supporting units;
- And a stopper fitted on an opened end of the second end of the housing to support the second supporting unit.
(canceled)
A stepping motor comprising:
- a housing provided with a guide portion for guiding a second supporting unit;
- a stator installed in the housing to form electric field;
- a rotor rotatably supported by the second supporting unit and inserted to be spaced away from the stator;
- a magnet fixed on the rotor to correspond to the stator;
- and
- a bracket having a third supporting unit in which a first side of the rotor is inserted, contacting an opening portion of the housing and a first supporting unit on which a second side of the rotor is rotatably supported.
A method for making a stepping motor, comprising the steps of:
- aligning a bracket and a single body housing using a pin;
- coupling the single body housing to the bracket;
- inserting a rotor in the housing and the bracket;
- and
- aligning a supporting unit on an end of the rotor.
