The IE5+ motor
MOTORING ON A
s the demand for increased automation continues to rise across almost all industrial sectors, the enabling automation
technology must evolve to keep pace with these changes, and motors and drives are no exception. From smaller and custom motor designs to improved drive networking and connectivity, new and unique applications require continual innovation and development from motor and drive system developers. Let’s take a look at some of the latest technological advances from the sector.
SAVING ENERGY AND MATERIAL Pitching itself as a pioneer in saving CO2 and material, Nord Drivesystems has exceeded the highest European standards efficiency class (IE5) with its new IE5+ synchronous motor. Designed to be both compact and energy efficient, the motor offers a constant high efficiency up to 93% and higher over a wide torque range, offering optimal energy performance in partial load and partial speed ranges. Not only saving energy but also emissions, the IE5+ motor reduces emissions by around 0.15t CO2 per year when compared with a conventional

Rounding up the latest product and technology developments in motors and drives
IE3 asynchronous motor, according to a model calculation. In large systems comprised of hundreds or thousands of drives, this adds up to an impressive total saving. In addition, the motor is also hailed for its material efficiency, having been designed as a 9-role synchronous motor in an IPM design. Tis 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. With 8-pole synchronous motors, the stator can also 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. “We were glad that we were able to significantly reduce the use of this material,” says Jörg Niermann, Nord Drivesystem’s Head of Marketing. “Various innovations in the motor design help us to realise significant material savings with our new IE5+ series. Our IE5+ synchronous motor combines energy efficiency with material
efficiency and thus scores twice in terms of sustainability.”
STRAIGHT OUT THE BOX On the drive side, industrial and electronic products supplier RS has launched a range of six ebm-papst drive development kits to help engineers to prototype and test new motor drive designs quickly and easily. Te kits are pitched as ready for use ‘straight out of the box’ by engineers who are looking to switch from other motor technologies to brushless DC (BLDC) motors with integrated controllers. Each kit includes a switch box which
replaces a PLC and enables the engineer to set digital or analogue inputs. Tese inputs dictate the unique parameters for how the motor will operate in a specific application and can control the speed and position. Supported by an intuitive and extensive programming and evaluation software interface suite, the kits include a programming module that can be used to set up operating
