This video show a sewing speed test of the Pfaff 230 vintage sewing machine. The speed shown is 1825 stitches per minute. It is a 4 mm wide zig zag stitch with Tex 70 polyester thread on the edge of 2 mm thick cotton webbing.
This high sewing speed is higher than most other household sewing machine can manage. In order to sew this fast, you need to have a more powerful motor, and Pfaff sold these Pfaff 230 sewing machines with a more powerful motor than all other household sewing machines, that I have seen. Normally household sewing machines have got a motor with an input power of about 80 W and an output shaft power of about 30 W. But the motor of this machine got a measured input power of 195 W and a shaft power of 82 W. It makes it able to sew faster, and the sturdy mechanics of this machine can handle it as well.
