Rotor for multipolar rotating synchronous electrical machine in slow-speed applications, has set of spacers, each creating space between two successive radial layers of field coil for circulating heat transfer fluid between layers

摘要

The rotor (100) has a set of spacers (14, 15a, 15b) i.e. plates, where each spacer creates a space (23) between two successive radial layers (11) of a field coil (3) for circulating the heat transfer fluid between the layers. A set of salient poles (10) is integrated to a crown i.e. rim (4), where the rim includes a recess formed of space (18) situated between two salient poles to cool the rotor. Each salient pole includes a set of removable pole tips (2) situated on both sides of a polar body (1). An independent claim is also included for a method for cooling a rotor of multipolar rotating synchronous electrical machine.
