High Voltage Induction Motors

250kW - 20MW Motors, 3kV - 15kV

This series of high voltage induction motors has been developed by an innovative re-engineering programme that defines a new standardised range of medium and large capacity high voltage induction motors, based on proven designs from LS and Brush. Using modular components and subassemblies, LS offer pre-engineered motors with some of the lowest whole-life costs in the industry, with the flexibility to satisfy almost all applications. The result is ATB Laurence Scott quality, at prices to suit the most competitive applications, for industries involved in all aspects of electrical machines, from power generation and water treatment to nuclear plant and defence users. This robust product is matched by the commitment and dedication of LS's engineering team, with after-sales support and service wherever required in the world, on plant or off-shore. All design, manufacture and testing is carried out in-house, by LS engineers at the LS complex in Norwich.
