Innovative drive configuration improves production in GKN foundry

GKN Sheepbridge Stokes is the UK’s leading manufacturer of cylinder liners for the automotive engine market. GKN has redesigned the control of their 8-head cylinder liner casting machine and is seeing substantial energy and production benefits from the innovative drive configuration used.

Tony Saunders, Electrical Project Manager at GKN " I decided a new approach was called for and carried out a detailed survey of the market for drives which would meet the demanding performance and environmental demands of the Nemesel machine. "
Danfoss VLT drives energy saving ECplus

Increase Efficiency - Save Energy

A key factor for energy savings in building services is the use of variable speed drives for compressors, pumps and fans.

There are two decisive factors here: the efficiency of the motor (and the machine) and the energy efficiency of the application control.

Because of their high efficiency, the use of motors with permanent-magnet rotors is increasing. Motors with this technolocy are know as 'EC motors' in the HVAC sector.

To allow the users to benefit from the high motor efficiency of EC technology in all areas, Danfoss has refined its tried and tested VVC+ algorithm - as used in the VLT frequency drives - and optimised it for operating PM motors.
