CAUSING A STIR
ENGINEERS AT WESTIN DRIVES came up with an innovative solution when they were presented with a paintstirring machine that was only able to run at one speed.

Fraser Lynch, Technical Manager at Westin Drives, explained that the machine’s owners needed to diversify their paint offering, but the bespoke, single-phase agitator was not up to the job. A cost-effective solution was needed to enable them to upgrade the unit so it could run at variable speeds to reduce over-agitation of certain paints and to increase it for others.
Because single-phase motors have limited and expensive variable speed drive controls, a progressive output three-phase motor and single to threephase IP66 inverter from Invertek was offered as a suitable engineering solution. Because it was still perfectly serviceable, the existing gearbox was retained.
The customer was delighted with this neat and effective solution and was able to adapt to present and future requirements with only 24 hours of downtime.
