Pole changing circuit for two speeds with separate windings
Functional description
A different speed can be achieved with three-phase a.c. motors by changing over to a different number of poles. The separate stator windings are changed over to various numbers of poles by a cam-operated switch. Step switches can also be used for random switching of several drives. The respective motor is switched according to the position of the switch.
