If you are passionate about sewing, you may have a home sewing machine with some extra bells and whistles, other than the basic sewing stitches. You might even have a serger.
But as you get more involved you realize the inadequacies of your simple sewing machine. You want to buy bigger, better. Or maybe you want to turn your hobby into a profession. Now it is another ballgame – you definitely need more. Maybe an industrial sewing machine and a computerized embroidery machine. Different Types of Sewing Machines
But many are surprised to learn that there are many different sewing machines than these obvious ones. Some of these categories overlap and some you may never even consider buying – but you can never say never. So here they are.
A scheme has been developed to reduce the no-load losses of the industrial sewing machine motors used in Ready Made Garments (RMG) industries. The switching arrangement of the machine is such that the supply voltage of the motor is partially dropped across a reactive device which is a capacitor connected in series with the motor while the motor is running at no-load. This reduced voltage to the motor reduces the no-load loss significantly. During load condition the switching mechanism of the motor replaces the reactive component by a wire connection and allows full power to the load. The validity of this mechanism is verified by simulation programs and results are tabulated with proper comparison. It is evident that the use of this motor controller reduces no-load loss of the sewing machines substantially and under load condition the controller improves efficiency of the machines. As the loading increase, the efficiency of the machine also increases.
