ELECTRICAL WORLD and ENGINEER. 535 Semi-enclosed Westiiighouse direct-current Type S motors havebeen adopted as standard, though a few of the multipolar open typeare also used. Strong and compact design, high efficiency, largeoverload capacity and cool operation combine to make this type ofmotor peculiarly suited to the requirements of machine driving. The.
