AC Motor DRK
The DRK.. motor in the modular DR.. series motor system is a single-phase motor that can be operated on a single-phase power supply (instead of the usual three-phase power supply). The DRK.. motor comes equipped with running capacitor CB.
DRK.. series motors can be operated on the following single-phase power grids:
– 220 V/ 50 Hz, 230 V / 50 Hz, 220 V / 60 Hz or 230 V / 60 Hz
The running capacitor integrated in the terminal box allows for operation under many demanding ambient conditions. SEW-EURODRIVE also offers ET56 and ER63 motors.
