Abstract
An automotive air blower includes an air pump () connected to the output shaft of a transmission system, whose input shaft is connected, in use, to the engine () of a motor vehicle. The input and output shafts are connected to the ring gear () and sun gear (), respectively, of a three-branch epicyclic differential gearset. The planet carrier () of the gearset is connected to the rotor () of an electric motor/generator and the input shaft is connected to the rotor of an electrical machine (), which constitutes at least a generator. The electrical connections of the stators of the two machines are connected together via a controller arranged to control the flow of electrical power between them. A selectively engageable mechanical connection () is provided between two of the branches of the gearset and arranged to connect the two branches together such that the gearset will rotate as a single unit.
