    Abstract: An electrical motor and drive (10) comprises a motor unit (13) having a stator (32) and a rotor (33) disposed inside a housing (29), the rotor (32) being supported inside the annular stator (33) by a shaft (30) which is rotatably mounted to the housing (29) by bearings (39). A variable speed drive unit (11) of the motor (10) comprises a plurality of electronic components (35), an elongate flow duct (19) and heatsink having elongate fins (17) which extend along the flow duct (19). A fan unit (12) is disposed between the motor and drive units (11, 13), the fan portion comprising a centrifugal fan (25) mounted on the shaft (30) and having a central air intake which faces axially towards the drive unit (11). The flow duct (19) extends to the fan intake so that the fan (25) draws air along the flow duct (19) to efficiently dissipate heat from the fins (17) and is expelled radially.

    Abstract: Disclosed herein are high-power hybrid electric jet propulsion systems and methods for creating thrust using electric propulsion and chemical reaction. Embodiments include powering a Stage1 (6) electric machines (6b) through motor controllers for spinning a shaft (5), which spins a fan (2) to draw in air through the engine cowl (1) into Stage1 (6) where it gets compressed and heated. The air is then passed into a cyclonic combustion chamber (7) for mixing with a fuel to create a medium (X1). The medium (X1) is then passed into the turbine blades (8a) in Stage2 (8) to the spin shaft (5). The shaft (5) is configured to produce the high bypass thrust (10) and the jet exhaust thrust (9).
