Fault on textile mill machine leads to improved efficency

A fault on a textile mill machine has led to improved efficiency for a West Yorkshire company.

​An engineer from Westin Drives was called out to the mill because of a problem with the drive system of a warping machine. 

​Its 45 year-old, oil-filled, variable-speed drive had ground to a halt during busy production.

The unit was removed for repair but our electrical engineer Barrie Harkness suggested an upgrade to the customer – which was accepted.

It was pointed out that this would enable production speed to be increased, so a target value of 50% additional output was established.

Using a WEG inverter, WEG motor and Motovario gearbox from stock, the machine was up and running in record time, with new sprockets replacing the worn originals.

The project also proved worthwhile for saving energy, as the old system ran continuously whether the machine was actually producing or not.

The new system retrofit only runs when required and at an optimum speed to match requirements.
