Cloth feeding driving motor of sewing machine

The invention relates to a cloth feeding driving motor of a sewing machine. The cloth feeding driving motor drives an output shaft in a rotation mode to drive a driving wheel and a synchronous belt to enable a driven wheel and a cloth feeding shaft to swing at a certain angle, so that a cloth feeding dog seat and a cloth feeding dog frame which are mounted on the cloth feeding shaft are promoted to swing at the same angle, and a feed dog obtains a front-and-back feed action. The cloth feeding driving motor is used for driving the synchronous belt to replace a swing seat to operate; the cloth feeding driving motor starts to rotate back and forth in the static state in the mode that the cloth feeding driving motor firstly rotates by 22.5 +/-2.5 degrees in one direction, then swings back by 45 +/-5 degrees and then circularly rotates back and forth at the angle of 45 +/-5 degrees to implement sewing with the stitch length of 5 mm, measurement can be carried out under the situation that the sewing machine is not
