NORD DRIVESYSTEMS IE5+ synchronous motor

Wednesday, 22 November, 2023 | Supplied by: NORD Drivesystems (Aust) Pty Ltd

The IE5+ permanent magnet synchronous motor from NORD DRIVESYSTEMS exceeds the efficiency class IE5. The compact and energy-efficient motor offers a constant high efficiency of up to 93% over a wide torque range, and thus also develops optimal energy performance in partial load and partial speed ranges. This means the motor not only saves energy, but also emissions.

In comparison to a conventional IE3 asynchronous motor, one single IE5+ synchronous motor is said to reduce emissions by around 0.15 t CO2 per year. In large systems, for example in intralogistics with hundreds or even thousands of drives, this adds up to an even bigger saving.

The product was created as an 8-pole synchronous motor in an IPM design. This reduces the size of the motor’s active components, which not only results in material savings in the sheet metal package but also in the magnet material. In the course of material savings, it was also possible to reduce the proportion of rare earth elements in the magnet material.

With 8-pole synchronous motors, the stator can be manufactured with the so-called single-tooth windings. As a result, valuable material such as copper is only used where it is actually productive, and inefficient use in the winding head is reduced.
