Abstract
Stepper drive motor Provided is a stepper drive motor, comprising a coil, a stator, a rotor and a shaft, wherein the coil is wound around the stator; the stator comprises pole pieces, a winding bobbin, a stator housing and a connector, the pole pieces and the stator housing are connected so as to form a magnetic circuit, the winding bobbin is provided with a protrusion, the connector is provided with a positioning and guiding structure which is shaped to match the protrusion, and the protrusion of the winding bobbin cooperates with the positioning and guiding structure of the connector so as to achieve the positioning of the connector; the rotor is arranged between the stator and the shaft; and the shaft extends through an interior of the rotor and a thread on the shaft is engaged with a thread of the rotor, so that the rotational movement of the rotor is transformed into a movement of the shaft. In the stepper drive motor of the present device, the protrusion of the bobbin cooperates with the positioning and guiding structure of the connector so as to position the connector, enabling a simple assembly of the stator connector.
