Abstract: A motor includes a frame defining an internal volume in which are housed a rotor and a stator; at least one cooling circuit, which includes a primary inlet and a primary outlet in fluidic communication with the outside of the frame; at least one cooling device outside the frame, which includes a secondary air inlet and a secondary air outlet, and a conduit; at least one secondary cooling circuit, separate from the primary circuit, crossing the rotor and in fluidic communication with the secondary inlet and the secondary outlet of the cooling device. The secondary cooling circuit is crossed by a channel of the primary cooling circuit supplying the stator with the gas fluid from the outside of the frame.
