30 Series Aluminium & Cast Iron Motors
Brook Crompton
Brook Crompton’s 30 Series is a comprehensive range of three-phase induction motors built to meet the diverse needs of modern industry. The aluminium variants (frames 80–225 M) serve light to medium-duty applications with outputs from 0.55 to 45 kW, while the cast-iron models (frames 160–355 L) are suited for heavier loads, powering 7.5 to 400 kW. All units are available in 2-, 4-, 6-, and 8-pole configurations and offer energy-efficient ie3 and ie4 options. Designed with a focus on quality and durability, these motors feature standard IP55 protection, inverter compatibility, and versatile mounting options (B3, B5, B14, B35), making them suitable for HVAC, pumps, conveyors, compressors, and OEM machinery.
Features
The 30 Series motors stand out for their robust construction and adaptability. The aluminium versions are light yet strong, ideal for applications that benefit from portability or lower mass. The cast-iron variants offer enhanced durability, making them ideal for demanding industrial or outdoor environments. Both designs support 2–8 pole speeds and come with standard IE3 or optional IE4 efficiency for sustainable operation. With rugged IP55 enclosures, inverter readiness, and flexible terminal box placement, these motors ensure straightforward integration and reliable performance. The range also includes thermal protection for motor safety and maintenance, with comprehensive documentation available.
