Emerson Introduces New High Power Modular Drives
Control Techniques, an Emerson business, extends its range of high power modular drives. Unidrive M and Powerdrive F300 variable speed drive ranges are now available in the larger frame size 11. Paralleled together, Unidrive M can reportedly 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, according to the company.
Unidrive M reportedly provides fast current control algorithms and high switching frequencies. Active Front End (AFE) solutions deliver torque precision and power quality, according to the company. The Unidrive M modules can be paralleled into solutions 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 high powered drive products for fan, pump and compressor applications from 90 kW to 2.8 MW. The Powerdrive F300 series features a modular design and can control permanent magnet or standard AC induction motors.
