For the use of regenerative energy sources such as wind power or water power, the asynchronous generator is a reliable and cost-efficient alternative to the conventional synchronous generator that is easy to maintain, even in small or medium-sized power generation equipment. Depending on the case of operation, asynchronous generators are operated on an in-house power supply system, or in parallel to an existing power supply system respectively. By now, the previous G21R / G22R type series are supplemented by the GE1R / GE2R type series the design of which is based on the IE-2 type series of asynchronous motors.
