The invention discloses a power assembly for a new energy automobile, and relates to the technical field of new energy. The power assembly comprises a casing, a rotor, a stator, a vent hole, a guide cylinder, a blast plate, a reciprocating lead screw, a control mechanism and a rotating speed detection mechanism for driving the control mechanism according to the rotating speed of the rotor. The reciprocating lead screw is coaxial with the rotor, and the rotating speed detection mechanism comprises a sleeve of which one end is fixedly connected to the rotor, a conductive ball connected in the sleeve in a sliding manner and a supporting protrusion which is fixedly connected into the sleeve and is used for supporting the side, close to the rotor, of the conductive ball, a spring which is connected to the conductive ball and applies force towards the rotor to the conductive ball, a conductive piece which is located on the supporting protrusion and is used for making contact with the conductive ball, and a pressure sensor which is used for detecting the pressure between the conductive ball and the supporting protrusion. The invention provides the power assembly for the new energy automobile. The power assembly is good in heat dissipation and enables the energy utilization rate to be improved.
