Four tips to select a dimensioned and efficient drive system
Electric motors are the unsung hero of the Fourth Industrial Revolution, bringing to life anything from robots to 3D printers. Unfortunately, they are not unbreakable and, when they do fail, can bring an entire production line to a halt.

Tip 3 – Keep one step ahead of breakdowns       

Changes to a motor’s conditions such as vibration, temperature, current intake and insulation resistance can all be signs of an imminent failure so keeping an eye on them in real time is key. This is exactly what some of the latest IIoT-enabled condition monitoring devices can do.

Omron’s K6CM range of motor monitoring relays, for example, automatically and continuously monitor vibration, temperature, current intake and insulation resistance of up to 10 motors. By displaying a motor’s status on an alarm bar in three colours - green (normal), amber (warning), and red (critical) – they immediately detect and flag up any abnormalities helping prevent breakdowns. Another key component to look for when monitoring a motor’s conditions are controllers. By connecting to monitoring devices such as monitoring relays or sensors, controllers such as Schneider’s Modicon M221 enable immediate access to a motor’s critical data from any location via Ethernet, wireless access and web servers. A maintenance engineer can receive alerts directly on their smartphone or tablet and perform predictive maintenance – for example by changing parameters remotely - to prevent potential failures.

Controller starter kits such as those offered by Siemens, which include power modules and all of the software required for easy setup, are a good way of getting started and there is a variety of options to choose from, from the most basic to the most advanced.
