A generator has a stator part 11 and rotor part 12 and a controller. The stator part comprises a plurality of stator nodes 13, each node comprising a core 18 extending generally radially, the core being surrounded by a coil 19 and the rotor part comprising a plurality of rotor nodes 22 mounted on a support part 20, the support part being mounted for rotation relative to the stator part. The rotor part further comprising a conductor 25, which may be tubular or formed of copper rods (85 fig 4), disposed between the rotor node(s) and the stator part. An angular position detector detects the position of the rotor relative to the stator, the controller calculating the position of the rotor and controlling the supply of electrical current to one or more stator nodes to as a rotor node passes the stator nodes. The rotor core may carry coils 24 which are supplied via a contactless rotary transformer arrangement 30 comprising stator cores and coils 32,33 connected to the controller and rotor cores and coils 36,37 connected to coils 24. A similar arrangement 40 removes the generated power from the conductor 25. Three phase current may be obtained by using 3 generators or alternatively three arrangements 40 relating to separate equiangular sections of the rotor. The specification also indicates that the generator can be operated as a motor. |
