Parts
A typical synchronous motor has the following parts:
- A stator winding, connected to the AC supply, which creates a rotating magnetic field.
- A rotor which turns within the stator field. In excited machines this carries a field winding supplied by DC current from the slip rings. This winding is an electromagnet. In non-excited machines, the rotor is a solid cylindrical steel casting, while in permanent magnet motors there are permanent magnets in the rotor.
- In DC excited machines, slip rings on the rotor supply the DC to the field winding from an external supply (some motors have other arrangements).
- The stator frame contains and supports the other parts and may include bearing housings.
Large machines include additional parts for cooling the machine, supporting the rotor, lubricating and cooling the bearings, and various protection and measurement devices.

Famous quotes containing the word parts:
“Even in ordinary speech we call a person unreasonable whose outlook is narrow, who is conscious of one thing only at a time, and who is consequently the prey of his own caprice, whilst we describe a person as reasonable whose outlook is comprehensive, who is capable of looking at more than one side of a question and of grasping a number of details as parts of a whole.”
—G. Dawes Hicks (1862–1941)
“Beauty that shocks you, parts that none will trust,
Wit that can creep, and pride that licks the dust.”
—Alexander Pope (1688–1744)
“Nature seems to have taken a particular Care to disseminate her Blessings among the different Regions of the World, with an Eye to this mutual Intercourse and Traffick among Mankind, that the Natives of the several Parts of the Globe might have a kind of Dependance [sic] upon one another, and be united together by their common Interest.”
—Joseph Addison (1672–1719)
