摘要： A dynamoelectric machine is provided with an arrangement in the form of a plurality of cooling tubes disposed in or adjacent the stator core of the machine and through which a coolant is caused to flow. The coolant tubes extend axially with respect to the rotor of the machine and are spaced around the circumference of the stator. In order to regulate the cooling efficiency and reduce the coolant pressure loss in the coolant tubes, a branching arrangement in combination with a valve arrangement is disposed in at least one of the end brackets of the machine to control the flow of coolant in parallel selectively through different combinations of cooling tubes. The branching arrangement includes a plurality of circumferentially disposed chambers which communicate with respective groups of cooling tubes in parallel, and the valve arrangement allows connection of these chambers selectively in different combinations to a coolant supply and a coolant exhaust. Thereby, the coolant tubes can be connected to form different combinations of parallel passages for carrying coolant to cool the stator of the machine.

摘要： A permanent magnet electric machine comprises a stator provided with windings and a rotor disposed with an air gap between the stator and the rotor. A plurality of permanent magnets are arranged along and fixed to the circumference of the rotor. The angular circumferential extent of a surface of each permanent magnet facing the stator is determined so that an induced voltage in the machine has a waveform that approximates a sinusoidal waveform, to suppress the peak of the induced voltage.
