Failures driven out
July 1st 2004

WEG distributor, Dorlec, has applied a matched WEG 200kw motor/drive package to solve a recurring problem of motor and inverter failure that was costing thousands of pounds in repair bills and lost production at SCA Hygiene in Chesterfield.

A wet end fan serving a large drying cylinder used to be controlled by a 200kw inverter/motor combination that had proved unreliable. Investigations revealed the problem to be a lack of direct short circuit protection against over currents on the main motor output circuit.

Dorlec advised replacement of the equipment, and a matched 200kw motor/drive package from WEG was installed. WEG backed this with a

3- year warranty and undertook to keep a spare drive and motor in stock at Dorlec.
