Abstract

The invention discloses a household sewing machine mechanical clutch electromechanical clutch motor, which comprises a motor casing, the bottom plate of the motor casing is fixedly connected with a support base, the motor casing is provided with an installation cavity, and the motor casing is provided with a The first installation groove connected with the cavities, the inner wall of one side of the first installation groove is provided with an installation hole, the first installation groove is provided with a rotating shaft, one end of the rotating shaft is fixedly sleeved with a pulley through the installation hole, and the rotating shaft The end away from the pulley extends into the installation cavity, the extension end of the rotating shaft is threadedly connected to the limit nut, the end of the rotating shaft close to the limit nut is slidably sleeved with a clutch driven disc, and the motor rotor is arranged in the installation cavity. The invention has a reasonable structural design, and the quick start and stop device of the clutch is controlled by the foot pedal, while the rotor speed of the motor is kept stable, the temperature of the motor does not change much, and the service life of the motor is improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a mechanical clutch electromechanical clutch motor of a household sewing machine. Background technique [0002] The nature of the work in the textile and sewing industry determines that the machinery needs to work in gaps. In the mass production line, the sewing machine is required to have a large torque, can start quickly, and stop the needle immediately. Most of the industrial sewing machine motors currently used are single. The single-phase asynchronous motor directly connects the rotor of the single-phase asynchronous motor to the output pulley, and the single-phase asynchronous motor itself starts and stops quickly, thereby increasing the temperature of the motor and greatly reducing the service life of the motor. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a household sewing machin...
