在PPPL的活动中，我们的大型垂直轴电动发电机提高了运营效率并降低了运营成本，证明是一个富有成效的领域。定子空气冷却回路中的测量损耗在1兆瓦的范围内。减少这些损失是PPPL和GE Hydro最近研究的重点。运行数据用于计算电动发电机的负载循环温度曲线。根据设计限制与运作情况之间的差距，估计每小时可节省约200千瓦的能源。确定了通过发电机定子冷却器的最佳空气速度，并制定了在不影响发电机绝缘极限的情况下减少流量的方法。
In PPPL's campaign to improve operating efficiency and reduce operating costs of our large vertical shaft motor generators proved to be a fruitful area. The measured losses in the stator air cooling loop were in the area of one megawatt. Reducing these losses was the focus of a recent study by PPPL and GE Hydro. Operating data was used to calculate the load cycle temperature profile of the motor generator. Based on the wide margin between design limitation and operating profile, the estimated energy saving is about 200 KW per hour. An optimum air velocity through the generator stator cooler was determined and means were developed to reduce the flow without compromising generator insulation limits.
