Control Techniques, an Emerson business, has extended its range of high power modular drives. Both its Unidrive M and Powerdrive F300 variable speed drive ranges are now available in the larger frame size 11, providing a flexible method of building compact, reliable high-power solutions. Paralleled together, Unidrive M can control asynchronous and permanent magnet motors in systems up to 2.8 MW (4,200 hp). The new frame 11 is a 250 kW (400 hp) module that allows system builders to create high power solutions with the smallest number of components, keeping both footprint and costs to a minimum.

Unidrive M differentiates itself on performance with extremely fast current control algorithms and high switching frequencies. Active Front End (AFE) solutions deliver unparalleled torque precision and power quality.

The Unidrive M modules can be paralleled into a wide range of flexible solutions to solve all system needs including Active Front End and multi-pulse rectifier configurations. They can be controlled by Control Techniques’ Unidrive M600, M700, M701 and M702 controllers.

Control Techniques also offers a full range of high powered drive products tailor-made for fan, pump and compressor applications from 90 kW to 2.8 MW. The Powerdrive F300 series also features a modular design and can control permanent magnet or standard AC induction motors. This modular approach to building high power systems also provides the flow industry with flexibility while keeping complexity low.
