Abstract:
1. A rotating electrical machine, comprising: a stator that includes a stator core and a stator coil; a rotor that rotates with respect to the stator; a refrigerant supply port through which a cooling medium is supplied to a coil end protruding from the stator core; and a guide member, disposed along at least a part of the coil end, for causing the cooling medium supplied through the refrigerant supply port to flow along the coil end, wherein: the guide member has a substantially semi-circular first guide member opening downward and a substantially semi-circular second guide member opening upward, the first guide member is disposed along an inner circumference of the upper half portion of the coil end, the second guide member is disposed along an outer circumference of the lower half portion of the coil end, and the width of the first guide member that is substantially equal to the inner circumference diameter of the stator coil is less than the width of the second guide member that is substantially equal to the outer circumference diameter of the stator coil.
