description The present invention relates to an end shield (10) for a rotary electric machine, including one or more feed channels (12) for feeding a coolant supplied from a channel formed in a rotor lamination stack (8) or in a shaft of the rotor (1) or between the rotor lamination stack and the shaft, wherein at least one feed channel (12) includes a cross-sectional constriction (15), the cross-section of the feed channel decreasing and then increasing in a radial direction relative to the rotational axis (X) of the machine.
