Drive
- No. of pumps -- max. 1
- Voltage [V] -- Power supply via PumpDrive only
IEC‐compatible, sensorless, magnetless synchronous reluctance motor of efficiency class IE4 (super premium efficiency) to IEC/CD 60034‐30 Ed. 2.0 (05‐2011) for operation with the KSB PumpDrive S or KSB PumpDrive R variable speed system. Suitable for connection to three‐phase 380‐480 V mains (via PumpDrive). The motor mounting points comply with EN 50347 specifications to ensure compatibility with standardised IEC frame motor applications and full interchangeability with IE2 or IE3 standardised asynchronous motors. Envelope dimensions lie within the limits for IE2 / IE3 motors as recommended in DIN V 42673 (07‐2011). The motor is controlled without rotor position indicators. The efficiency of the motor also exceeds 95 percent of nominal efficiency when the motor runs at 25 percent of its nominal power on a quadratic torque‐speed curve. The motor is magnetless which means that, in particular, so‐called rare earths are not used in production. Drive production is thus sustainable and environmentally friendly.
Applications:
For use with dry‐installed variable speed pumps which can be driven by standardised foot‐mounted and/or flange‐mounted motors.
