Abstract
An object of the present invention is to provide a rotating electric machine that is capable of suppressing an increase in the pressure loss of refrigerant flowing through a cooling channel. A refrigerant channel in a statorof the rotating electric machineaccording to the present invention has: a first refrigerant channelthrough which refrigerant flows in the circumferential direction; second refrigerant channelsA,B through which the refrigerant flows in the axial direction; third refrigerant channelsA,B through which the refrigerant flows in the circumferential direction; and a refrigerant supply channel. The refrigerant supply channelfirst supplies the refrigerant to the first refrigerant channel. The first refrigerant channel, the second refrigerant channel, and the third refrigerant channelare configured so that the refrigerant supplied to the first refrigerant channelflows from one second refrigerant channelA to one third refrigerant channelA, and the refrigerant supplied to the first refrigerant channelflows from the other second refrigerant channelB to the other third refrigerant channelB.
