Brazilian WEG is one of the world's leading suppliers of electric motors from more than 50 years of tradition. The production program includes generators, asynchronous, synchronous, inductive and DC motors. Another group is their accessories for simple control and control in the form of frequency converters, soft-starters and relays.

WEG Motor Scan® brings new monitoring functions


The sensor automatically sends information to the cloud, which allows immediate monitoring of the performance of various devices remotely.

WEG Motor Scan® Brings New Features for Monitoring

Always in the field of innovation and technology, WEG brings a new WEG Motor Scan® to its portfolio of solutions for industry 4.0, which extends the performance of the electric motor monitoring sensor to various devices. In addition, it also monitors gearboxes, pumps, compressors and other devices driven by electric motors.

How does WEG Motor Scan® work?

The WEG Motor Scan® sensor reads data from the device, sends it to the cloud via smartphone or Bluetooth® or automatically from the gateway. All information collected is stored in a cloud that allows remote access to ensure process efficiency. The solution, originally developed for the electric motor, now includes additional equipment for measuring vibration and temperature. Another evolution of WEG Motor Scan® for Industry 4.0, which is now even more efficient.

Effective as always. Complete like never before.

One of the main benefits of WEG Motor Scan® is the optimization of predictive maintenance, as it allows the accurate identification of devices that may represent future failures, making the maintenance process faster and more efficient with minimal or no production downtime. Based on the data captured and sent to the cloud, it is possible to make faster and more assertive decisions, which ensure higher efficiency and longevity, and therefore guarantee the integrity of the equipment installed in production
