Problems solved by technology

[0002] At present, the main shaft of the existing sewing machine is linked with the motor shaft through a coupling, and there is always a large coaxiality error in the linkage between the two, which will cause the power transmission of the motor shaft to be unstable and easy to generate vibration. It will inevitably cause damage to the machine and bearings, and at the same time cause a waste of energy. The motor runs hard, so there is power loss

Abstract

The invention discloses a sewing machine and a driving device thereof. The driving device comprises a casing, a driving motor and a controller. The driving motor is provided with a motor rotor and a motor stator. The motor stator is provided with a first through hole. The motor rotor is provided with a second through-hole. A main shaft of the sewing machine serves as a motor shaft, is fixedly arranged in the second through hole to be circumferentially and fixedly connected with the motor rotor, and passes through the second through hole to be connected with an encoder. Compared with the priorart, the sewing machine and the driving device thereof have the advantages that existing technical prejudices are overcome, coaxiality errors are minimized to ensure smooth power transmission of the driving motor, the operating accuracy and output conversion rate are increased, abrasion of the machine during operation is reduced, and the service life of the machine is prolonged.

Description

【Technical field】 [0001] The invention relates to the field of sewing machines, in particular to a driving device for a sewing machine and a sewing machine thereof. 【Background technique】 [0002] At present, the main shaft of the existing sewing machine is linked with the motor shaft through a coupling, and there is always a large coaxiality error in the cooperation between the two, which will cause the power transmission of the motor shaft to be unstable and easy to generate vibration. It will inevitably cause damage to the machine and bearings, as well as waste of energy, and the motor will run hard, resulting in power loss. 【Content of invention】 [0003] In order to solve the above problems, the present invention provides a driving device for a sewing machine and a sewing machine using the driving device. The driving device has the advantages of simple structure, easy manufacture and assembly, stable power transmission, and not easy to cause machine strain. [0004] ...
