Abstract
A rotor (14) includes: a rotor core (24) having rotor salient poles (32) disposed in circumferential directions of the rotor core (24); a rotor coil (28n, 28s, 30n, 30s) which is formed by windings wound around the rotor salient poles (32) and whose external shape is fixed; and a retainer member (36) that retains the rotor coil (28n, 28s, 30n, 30s) on the rotor core (24), and that has a T sectional shape and has a leg portion (50) that is latched to a radially inner-side portion of the rotor core (24), and a beam portion (52a, 52b) which is connected to a connecting portion that includes a radially outer end portion of the leg portion (50) and which extend from the connecting portion in two opposite directions orthogonal to the leg portion (50). The external surface of the rotor coil has a non-contact portion that does not contact the retainer member (36).
