This paper presents a permanent magnet synchronous motor (PMSM) servo drive system for high speed flat industrial sewing machine. In order to satisfy the special function of sewing machine, several approaches are applied in this servo system: Using
ii Integrated EMI/Thermal Design for Switching Power Supplies Wei Zhang (ABSTRACT) This work presents the modeling and analysis of EMI and thermal performance for switch power supply by using the CAD tools. The methodology and design guidelines are
This paper presents a simplified HF injection method for permanent magnet synchronous motor (PMSM) sensorless control. The discussed HF injection scheme utilizes motor magnetic saliency property which contains the information of the rotor position d

2014年5月15日 The purpose of this book is to provide an integrated course in real and complex analysis for those who have already taken a preliminary course in real analysis. It particularly emphasises the interplay between analysis and topology. Begin
The effects of eddy currents in transformer windings are considered, and a method is derived for calculating the variation of winding resistance and leakage inductance with frequency for transformers with single-layer, multilayer and sectionalised w
This is the fifth edition of a one-of-a-kind engineering reference book covering the past, present, and future of mechanisms and mechanical devices. It includes clear illustrations and straightforward descr iptions of specific subjects rather than t
