The condition monitoring solution presented last year, which can be installed as a retrofit, enables the real-time monitoring of WEG electric motors for the purpose of predictive maintenance. The collected data can now be transmitted to a secure cloud using gateway technology - previously via an intelligent device app and Bluetooth. From there, the user can retrieve it via the app or the WEG IoT Platform web portal. This enables a detailed analysis of the monitored electric motor.

WEG Motor Scan makes predictive maintenance measures possible in a simple and cost-efficient way, which, according to the company, leads to an extended service life of the motors and increased system availability. When WEG Motor Scan was announced, the gateway was already planned and its features were in high demand from users. The gateway extension now enables users to automatically collect data from the WEG Motor Scan sensor, eliminating the previous intermediate step via the mobile app. The gateway, consisting of firmware and hardware, complements the existing mobile app and works as a router that detects all installed sensors within a distance range of around 30 meters in an industrial environment. The integration of WEG Motor Scan and gateway brings significant added value through increased user-friendliness and automation.

Another new feature is the expansion of the CFW500 to include size F with a rated power range of up to 55 kW. The new CFW500 operates in a voltage range from 380 to 480 V. This opens up new possibilities for the user in the higher power range in a variety of industrial applications, especially in general mechanical engineering for conveying, turning, lifting, pumping and ventilation. The new power class rounds off the main areas of application for the CFW500 in small and very small applications. The integrated safety functions STO (Safe Torque Off) and SS1 (Safe Stop 1) provide machine builders with a cost-effective and flexible solution for reducing the risk of unexpected and unforeseen events. This includes the prevention of unexpected machine start-ups, emergency shutdowns and controlled stops.

Frequency inverters, soft starters and contactors

The decentrally designed MW500 frequency inverter has also been updated: it is now also available for lower outputs in the range from 0.37 to 2.2 kW and is available for mains voltage 380-400 V in sizes A and B. The robust housing design in protection class IP66 or Nema 4X allows the frequency inverter to be mounted directly on the motor terminal box frame or on the wall using an adapter plate.

WEG has also further expanded its SSW900 soft starter series. To date, the series has covered output currents from 10 A to 412 A in the wide voltage range 220 - 575V 3AC in four sizes A to D. Size E is now also available for output currents from 480 to 670 A.

The CWBS contactor series, which the company has developed for safety applications from 9 A to 80 A, is completely new. They comply with the IEC 60947-5-1 standard for mechanically connected contacts and mirror contacts (IEC/EN 60947-4-1).
