AC or DC – The decision is yours GE has an offering whether you need an AC or DC solution. Our systems approach emphasizes a solution optimized to your application, with high productivity, high availability and drop-in mechanical compatibility with AISE MD motor standards for both AC and DC applications. GE Excavator Solutions The system hardware and software has been specifically engineered to meet the needs for excavator applications: • High performance • Proven reliability AC solutions offer state-of-the-art IGBT variable frequency drives, while our DC solutions offer high performance using...

The AC system is a complete motion solution comprised of an integrated family of power delivery elements, Variable Frequency Drives (VFD), AC motors and controls. Each system is designed for the specific application using motors of various frame sizes and mounting orientations (horizontal and vertical) and drives tailored to the The AC system is designed to use a master PLC to control system functions, maintaining commonality of equipment and control algorithms with existing DC excavator systems. Our newly designed air-cooled AC KD800 series motors are mechanically interchangeable with our existing...

The new family of AC Variable Frequency Drives (VFD) have been developed using a modular approach. GE's system is designed to your specifications using a common set of modules and passive components, improving availability • Four-quadrant control of all motor functions with active power factor correction • An air-cooled drive system designed for minimal maintenance with extended filter change intervals • AFEs and Inverters configured as Master/Slave with an automatic fail-over feature, which allows for reduced-capability operation until • System communication networks use standard The Active...

The DC system uses Ward Leonard controls with synchronous machines driving MG sets, all controlled by field exciters. The field exciters are IGBT chopper technology-based and deliver a high performance, modular control system tailor- The field exciters use digital regulators that provide generator and motor control functions by controlling armature volts and amps to levels that maximize productivity and minimize equipment stress. The field exciters control the synchronous motor excitation to provide system reactive power support during motoring and regeneration as well as line voltage transients....
