Electronic motor starter increases machine availability and minimises downtime

Written by: Tom Austin-Morgan | Published:

Eaton is helping the industry to increase machine availability and minimise downtime with its new generation of multifunctional electronic motor starter (EMS) with SmartWire-DT connectivity. This is achieved mainly through the advanced communication capability of the switching device. In combination with SmartWire-DT, more relevant motor data is documented and communicated to the EMS than before.

The EMS features direct motor start, reverse motor start, motor protection and safe shutdown. By reducing the overall component count and using tool-free, push-in technology, the wiring costs in comparison with conventional switchgear devices may be reduced by up to 60% and the proportion of hardware components required by up to 70%.

Due to the wide-range overload protection feature of the EMS device, two current range models are needed; the AC-53a (0.18 to 6.5A) and the AC-51 (9A). In addition, the integrated hybrid circuitry operates virtually wear-free, increasing predicted lifespan compared with conventional switchgear devices, providing machine builders with additional reliability.

With a width of 30mm, it also saves valuable space in the control cabinet compared to conventional 45mm models. The main fields of application for the EMS, which achieves outputs of between 0.06 and 3kW, include conveyor systems for machine handling and logistics and packaging equipment.
