Active temperature control for generator in power train

A system comprising:

• a power train assembly having a generator component and a power train component mounted on a same shaft;
• a temperature sensor configured to monitor a temperature of the generator component;
• a heat exchange circuit in thermal communication with the generator component, wherein the heat exchange circuit is configured to cool the generator component with a cooling fluid;
• and
• a controller coupled to the temperature sensor and the heat exchange circuit, wherein the controller is configured to:
• calculate a target temperature for the generator component based on a target thrust bearing parameter or a target vibration parameter for the power train assembly, and
• adjust a delivery of the cooling fluid to the power train component based on a difference between the monitored temperature and the target temperature.
