摘要： Dual-motor sewing machine with automatic timing adjustment. In some embodiments, a sewing machine may include a frame, a needle bar configured to have a needle, a first motor configured to cause the needle bar to linearly reciprocate the needle with respect to the frame and into and out of a fabric, a first sensor configured to continuously sense a current position of the needle, a bobbin hook configured to function in connection with a bobbin, a second motor configured to cause the bobbin hook to rotate with respect to the frame, a second sensor configured to continuously sense a current position of the bobbin hook, and one or more motor controllers. The one or more motor controllers may be configured, based on the current positions sensed by the first sensor and the second sensor, to continuously and automatically adjust and synchronize timing of the first motor and/or the second motor.
