Abstract
Disclosed herein is a step motor. The step motor includes a casing, a stator disposed in the casing, with a coil being wound around the stator, a rotor disposed in the stator, having a rotor shaft that is rotatably supported at both ends of the casing, and rotated by interaction with the stator, a rotary sensing unit provided in the casing to detect a rotation of the rotor, and a coil connector formed on an outer surface of the stator, with an end of the coil being connected to the coil connector.
Claims9
A step motor, comprising:
- a casing having an opening at first side;
- a stator disposed in the casing, with a coil being wound around the stator;
- a rotor disposed in the stator, having a rotor shaft that is rotatably supported at both ends of the casing, and rotated by interaction with the stator;
- a rotary sensing unit provided in the casing to detect a rotation of the rotor;
- and
- a coil connector integrally formed on an outer surface of the stator, with an end of the coil being connected to the coil connector, and
- wherein
- the coil connector is spaced from an inner circumferential surface of the casing,
- the coil connector is disposed between the opening and the coil,
- the coil is disposed along a same axis in the coil connector,
- the coil connector comprises at least one coil connection terminal,
- the stator comprises on an outer surface thereof a pair of flat surfaces that are symmetrical with respect to a center of the stator and the coil connection terminal is formed on each of the pair of flat surfaces,
- the pair of flat surfaces is formed by cutting a part of the circular circumference of the stator, and
- the coil connection terminal is formed on the pair of flat surfaces or around the circular circumference.
