The drive for decarbonization is causing industrial businesses across North America to electrify their operations by switching from diesel-fuelled pumps to systems powered by electric motors. This is especially true in the chemical and energy industries where there is a major trend to deploy heavy-duty horizontal electric pumps. To meet this demand ABB has developed the new ECP5000 series Severe Duty motors to provide exceptional performance and maximum uptime in harsh industrial processing applications.
Until quite recently, operators in North America regarded medium voltage (MV) technology, typically at 4 kilovolt (kV) or above, as essential for their high-power motors. This started to change with the growing adoption of variable frequency drives (VFDs) that offer very significant energy savings. Using a high-power LV motor together with an LV drive provides a more cost-effective solution than MV equipment.
The capability of the ECP5000 series Severe Duty motor to deliver up to 1000 Hp (745 kilowatt) has been achieved by a process of evolution rather than revolution, as Robert Boyce, ABB Local Division Manager, IEC LV Motors – US, explains: “High power, low voltage motors are well established in IEC markets. So, our challenge was to put this wealth of knowledge into a format with mounting dimensions and shaft height to match the existing installed base. To do this we stripped the motor design down to its individual elements and optimized each one. We then used this as a set of building blocks to create our ideal, flexible design.”
Robert continues: “The key success of the ECP5000 motor is that even with the lowered shaft height we have been able to minimize vibration to ensure a long and reliable service life in the most demanding conditions. In essence, we have delivered the virtues of IEC motor design in a NEMA-dimensioned package to meet customer needs.”

Attention to energy efficient design enables the ECP5000 motor to meet IE4 levels in direct online installations. This is equivalent to NEMA Super Premium Efficiency. When used with a VFD, the motor is capable of achieving IE5 according to IEC TS 60034-30-2, the highest level currently recognized.
Other advantages of the ECP5000 motor are its robust cast iron IP66 enclosure combined with a large, left hand side conduit box that can be rotated in 90-degree increments or converted to right hand side or top mounting for ease of connection.
