How to size a motor & drive system

Proper sizing is a crucial aspect of motor selection. If a motor is undersized, it will not be able to control the load, leading to overshoot and ringing. Over-sizing a system is as bad as under-sizing – it may control the load but it will also be larger and heavier, as well as more expensive in …

What is Overall Equipment Effectiveness and how to calculate it?

The Overall Equipment Effectiveness (OEE) measures the manufacturing productivity by indicating the degree to which a manufacturing plant is truly productive. It can be used to monitor the efficiency of the manufacturing processes and help to identify areas for improvement. This metric allows the identification of losses, benchmarking progress and improving the productivity of the …
