摘要： An arrangement for cooling a rotor of a motor, generator or alternator wherein at least one cold plate element is disposed between a rotor pole and its associated winding. One or more cold plate elements surround each pole and are in substantial contact therewith. In addition, each cold plate element is also in substantial contact with the pole winding. As a result, each cold plate element serves to conduct heat from both the pole and its associated winding. To enhance the cooling capabilities of this arrangement, each cold plate element may incorporate passageways for conducting a cooling medium through the element. Advantageously, the resulting rotor assembly is suitable for retrofit into existing applications having strict rotor size and weight requirements. In addition, this assembly is suitable for use in alternators, generators or motors, whether alternating current or direct current.

摘要： A control scheme for a wound rotor synchronous generator whereby feedback signals corresponding to the exciter field current and the generator output voltage potential combine together to control the generator output voltage in such a way that at lower generator speeds and lower load requirements, exciter field current saturation is eliminated by reducing generator output voltage. The generator control scheme includes a circuit for sensing exciter field current in logic cooperation with a circuit for sensing generator voltage. Both sensing circuits regulate the current applied to the exciter field which corresponds to the rectified current applied to the field windings of the power generator. During steady state operations the generator output voltage is regulated using the generator output voltage as a feedback signal. At lower speeds and reduced loads and as the exciter field current approaches the saturation point, the generator output voltage is regulated using the exciter field current as a feedback signal.
