Abstract

1302179 Electric motors JOSEPH LUCAS (INDUSTRIES) Ltd 29 April 1970 [3 Feb 1969] 5610/69 Heading H2A [Also in Divisions B2 and F1] A pump, e.g. for use in aircraft fuel tanks is driven by an electric induction motor, and comprises a rotor formed with one or more helical impeller vanes 16 and carrying windings 34 of the motor. In use, a small portion of the pumped fuel leaving the rotor escapes to lubricate and cool the bearings 20, 21 and 27, 28.
