摘要： A method for supplying an excitation current to an excitation winding of a rotor of a three-phase generator of a system for producing a three-phase alternating voltage to be fed into a power network. A pulsed excitation current is supplied to the excitation winding if a rotational frequency of the rotor deviates from a network frequency of the power network.

摘要： A cooling device for an electric motor includes at least one closed capillary tube, within which a cooling fluid is located and which is introduced into an opening of a lamination stack of the electric motor such that the capillary tube is connected to the lamination stack to conduct heat and partially projects out of the lamination stack, such that the capillary tube has a cold end disposed outside and a hot end disposed inside the lamination stack. The cooling fluid and the degree of filling of the capillary tube with the cooling fluid is chosen such that an input of heat from the lamination stack into the capillary tube leads to evaporation of the cooling fluid, and the cold end of the capillary tube is cooled such that vapour produced during the evaporation condenses and heat input into the capillary tube is dissipated out of the capillary tube.

摘要： An electric machine having a stator and a rotor arranged on an axis of rotation and a first fan, which extends in the radial direction on one section of the axis of rotation and delivers a coolant flow into the electric machine during operation. The electric machine further includes a fan directing element, which interacts with the first fan and deflects at least a proportion of the coolant flow. Variable and demand-based cooling of the electric machine can be achieved by the fan directing element, which can in particular be adjustable.
