Three-Phase Asynchronous Generators
Asynchronous generators are used to recover braking energy back into the system (“regenerative braking”), as well as to generate electrical energy. Speed and power factor are independent of this. In order to generate energy, the asynchronous generator requires a supply network (grid-excited asynchronous generator) or a parallel-connected capacitor bank in isolated operation (capacitor-excited or self-excited asynchronous generator).

In order to adapt the machines to different applications and for monitoring and documentation purposes, the machines can be equipped with the following additional devices:
- brakes
- incremental encoder for speed measurement
- PTC, KTY and PT 100 for thermal monitoring and the protection of motor windings and bearings
- carbon brush monitoring
- anti-condensation heating for fluctuating ambient temperatures
- voltage regulator
- starting resistors
- leakage sensors
- couplings
- slip ring area lighting
