Patent number: 8581455Abstract: An electric machine (10;100) comprises a rotor (14a), preferably having permanent magnets (24a,b), although other field generation means are available, and a stator (12). The stator has coils (22) wound on stator bars (16) for interaction with the magnetic field of the rotor across an air gap (26a,b) defined between them. The rotor (14) comprises a housing (54) of a chamber (70) containing refrigerant (82). The rotor housing (54) has heat dissipating fins (96) accessible by the open environment whereby air movement relative to the housing caused at least by rotation of the rotor absorbs heat from the fins. The machine may be an axial flux machine, the coils being wound on bars that are disposed circumferentially spaced around a fixed axle of the machine forming a rotational axis (80) of the rotor. The machine may be a wheel motor for a vehicle, wherein the wheel is mounted directly on the rotor housing (14).Type: GrantFiled: April 13, 2010Date of Patent: November 12, 2013Assignee: Isis Innovation Ltd.Inventor: Tim Woolmer

Patent number: 8558487Abstract: A remote controlled circuit breaker for battery powered riding toys and method of using is disclosed. The circuit breaker is capable of being installed into standard electrical systems of battery powered riding toys via complementary connectors. If the child encounters danger while riding, the handler of the remote control can push the “Stop” button to switch the circuit breaker, thus preventing electric current flow through the toy. Once danger is averted, the handler of the remote control can push the “Go” button, which switches the circuit breaker to allow current flow from the battery to the motor, and thus allowing movement of the vehicle.Type: GrantFiled: March 2, 2011Date of Patent: October 15, 2013Inventor: Steven W. Gabbie
