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, as is usually the case with fans, pumps or compactors, we recommend the DRK.. 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.

Only half the solution without a gear unit? No problem at all as geared single-phase motors are assembled from an extensive modular concept just like gearmotors.
