III. Synchronous Motors
www.uotechnology.edu.iqSynchronous motors are often direct-coupled to the load and may share a common shaft and bearings with the load. Large synchronous motors are usually started acrossthe - line. Occasionally, reduced voltage starting methods, such as autotransformer or part-winding starting, may be employed.
