KSB SuPremE® in IE5*: the energy diet for your system

Cut your energy costs by up to 70 percent and more ─ with the most efficient magnet-less pump motor in the world. The KSB SuPremE® motor is so energy-efficient that it meets IE5* efficiency requirements. Discover the benefits of synchronous motor technology and familiarise yourself with the way this innovative drive solution works.



Why the KSB SuPremE® IE5 motor* is so efficient is also explained in our interview with experts.

The motors are well suited not only for driving pumps but just as well for powering fans and other rotating equipment.

* IE5 in accordance with IEC/TS 60034-30-2 up to 15/18.5 kW (only for 1500 rpm types rated 0.55 kW,
0.75 kW, 2.2 kW, 3 kW, 4 kW: IE5 in preparation)


Convincing facts

The new KSB SuPremE® motor generation for first-class efficiency and an excellent eco-balance

  • In combination with a PumpDrive speed control system, KSB SuPremE motors save up to 70 percent or more in comparison with fixed speed asynchronous motors. The motor alone can save up to 15 percent.
  • Especially in the part-load range, the motors have major efficiency advantages over speed-controlled asynchronous motors.
  • With KSB SuPremE® you satisfy the IE5 efficiency requirements to IEC/TS 60034-30-2 for electric motors according to the applicable ErP regulation up to 15/18.5 kW (only for 1500 rpm types rated 0.55 kW, 0.75 kW, 2.2 kW, 3 kW, 4 kW: IE5 in preparation).
  • KSB SuPremE® motors have an excellent eco-balance. Their non-use of magnetic materials makes them much more sustainable than permanent-magnet synchronous motors or asynchronous motors.
  • Thanks to the use of non-critical, long-lasting materials, the motors are extremely robust and durable.
  • KSB SuPremE® motors are compatible with IE2 asynchronous motors. Their patented rotor design ensures an extremely low level of torque ripple (one to two per cent) and accordingly quiet operation.

Efficiency comparison

The efficiency advantage of KSB SuPremE® motors is apparent at full load, but even more so at part load. And that is exactly where most pumps' drives operate.

The technology for your efficiency

What makes the KSB SuPremE® motor so efficient is an interplay of numerous technical innovations. Learn more about the slender pump drive for the future.

KSB SuPremE - The technology for your efficiency

1. Quiet rotor blade geometry

The matter-of-fact designation US patent 5.818.140 pertains to the special cut of the laminated rotor core. It is enormously effective, allowing only extremely little torque ripple (1-2%) for extremely quiet operation.

KSB SuPremE: quiet rotor blade geometry

2. Magnet-less and ecological

KSB SuPremE® motors have an outstandingly small total environmental footprint. Their non-use of magnetic materials makes them much more sustainable than permanent-magnet synchronous motors and asynchronous motors.

3. PumpDrive speed control system

KSB's PumpDrive, which has proven to be very effective in combination with an asynchronous motor, adjusts the speed of the motor - and with that the pump's flow rate and head - to match current demand. KSB SuPremE® is the only synchronous reluctance motor with a motor-mounted speed control system.

4. Durable and robust

The reluctance principle is fully matured. Thanks to the use of non-critical, durable materials, KSB SuPremE® motors are as robust as asynchronous motors. Their lack of sensors additionally reduces the probability of failure. And the lower temperature of the rotor has a positive effect on the service life of the bearings.

KSB SuPremE: durable and robust

5. Compatible

Wherever there is room for an IE2 asynchronous motor, a KSB SuPremE® motor with identical connecting dimensions can also get the work done efficiently.
