For random motor changes (e.g. selecting various drive units or changing the speed of motors with separate hetero-pole windings)
- Can be combined with many options
- Compact design
- Changeover by cam switch
Use in Series

Pole changing circuit for two speeds with separate windings
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.
