Abstract
Provided is a rotating electrical machine capable of downsizing. The rotating electrical machine includes: a stator () including an armature winding (); a rotor () provided inside the stator () in a rotatable manner; a power circuit unit () including a power circuit semiconductor switching element, for supplying a current to the armature winding (); and a control board () in which an energization-allowed time corresponding to revolution speed of the rotor () is set, for controlling supply of the current by the power circuit unit (), in which the control board () stops the supply of the current by the power circuit unit () when an integrated time of energization times to the armature winding () is longer than the energization-allowed time.
