Due to the elasticity of thread and tissue material, the stitches made by a computer program on a CNC sewing machine are shifted from their desired positions. The mismatch leads to a visually inferior appearance of the resulting thread pattern compared to the one intended by the manufacturer. This paper introduces a camera based inspection system that helps to find and evaluate the distortion vector for each individual stitch. These vectors can facilitate the automatic reprogramming of corrected stitch positions in the CNC sewing program to minimize the final distortion. An image processing pipeline is proposed, consisting of thread detection and model-based registration, finding an assignment of thread pixels and model stitch positions. The corresponding distortion vectors are computed for every individual stitch. second hand sewing machine in chennai

As it is known to all, PMSM becomes more and more popular in the field of the production of electric vehicle nowadays. However, the control performance at low speed of the motor is still influenced by ripple torque because of harmonic wave. Space Vector Pulse Width Modulation (SVPWM) is available to improve the quality of the stator currents and reduce the ripple torque remarkably. usha sewing machine service centre in chennai

Speed measurement is supposed as the first step for position determination. In this case we make use of three HALL sensors which are fixed on the surface of the motor with 120 mechanical degree’s phase delay. It is capable of generating such waves demonstrated in  when the motor is running. And from  we can also find that each HALL state indicates an operating sector of the motor. Click Here

The coordinate file will feed into the embroidery machine for the recreation of the design pattern on the surface of the product. Commercial graphic software does not provide the suitable function to transform each stitch point into their respective coordinate values. This drawback is resulted in the transformation process to be done by hand and by means of measuring each stitch point by designer - one point by one point.
