Eaton enters the enclosed drives market in Europe

21 November, 2017

Eaton is entering the enclosed drives market in the EMEA region and is launching this extended capability at this month’s SPS IPC Drives exhibition in Germany. The company will offer combinations of drives, protection and control equipment built into pre-wired and tested cabinets, which can be configured to user requirements. The range will cover power ratings from 18.5–630kW, 400V.

Customers will be able to specify options such as multi-pump modules, PLCs and Eaton’s SmartWire-DT communications and control system. Other options will include circuit-breakers, fuses, braking resistors, buffered 24V supplies and SIL3 compliance. The enclosures will incorporate a dirty air channel and will be available in low-harmonic versions (active or passive).

According to Rainer Günzel, Eaton’s EMEA product manager for general-purpose and enclosed drives, the company plans to differentiate itself from others in the market by providing smaller systems with options that its rivals don’t offer. “We don’t want to be a me-too product,” he says.

The enclosed drives will be based on Eaton’s DG1 general-purpose drives and can be supplied with sine filters rated up to 90kW. The drives have an active energy control function which, Eaton claims, can reduce energy consumption by 2–10% more than rival drives, without needing any motor tuning. The function adjusts the V/Hz curve dynamically to optimise efficiency.

The drives incorporate DC link chokes, rather than line reactors, which Eaton says will save space and costs as well as reducing total harmonic distortion by more than a line reactor. The DC chokes use input surge protection to provide the same transient protection as line reactors, while avoiding voltage drops.
