The running capacitor integrated in the terminal box is the special feature of our Sew Eurodrive single-phase motors of the DRK.. series. This does not only make the motor especially compact, it also enables application areas up to degree of protection IP66.
The compact single-phase motor with built-in running capacitor
Be it in Europe and the USA or in Brazil: you can operate the DRK.. motors in many power supplies because they are available in 50 Hz or 60 Hz with 220 V or 230 V. In total, there are six sizes available in the power range of 0.18 kW to 1.1 kW.
If you do not require a high starting torque in your applications, e.g. for fans, pumps or compactors, we recommend DRK..Sew Eurodrive single-phase motors with integrated running capacitor. The motor becomes more compact as the running capacitor is housed directly in the terminal box. This means that approx. 45% to 50% of the nominal torque is available for start-up.
With an additional start-up capacitor, the motor is suitable for screw conveyors and conveyor belts as well as for agitators and dosers. You can expect a torque of approx. 100% to 150% of the nominal torque.
It goes without saying that everything fits together for single-phase motors and you can use many additional features of the DR.. modular motor system.
