Description

This paper reports the study on manufacturing technology of a small and powerful AC servo motor which used for industrial devices. This motor has a linear shaped core which is divided among teeth and connected by thin bridges. In coil winding the linear shaped core is wound by several nozzles. After winding, the linear shaped core is bent as a similar conventional circular stator. This manufacturing method brings the coil density to improvement of 30-40% and the optimization of the width of the slot opening. As a result, it can be realized that 40-60% of the motor capacity has decreased in comparison with before.
