Patent number: 8061171Abstract: The present invention provides a method and machine for producing a slotted wound core (50). The machine includes a punch arrangement (16) arranged to punch apertures in a length of material (12a), a mandrel (22) for receiving the punched material, a control means and a mandrel indexing means. The positioning of the punch arrangement (16) and the mandrel (22) is fixed and the mandrel (22) is arranged to be rotated by the mandrel indexing means after each operation of the punch arrangement so that a roll of punched material is formed on the mandrel (22). The mandrel (22) is rotated by an amount (&ggr;) determined by the control means. The control means determines the indexed amount so that selected apertures punched in the length of material align with one another when the material (12a) is rolled onto the mandrel (22) so that the aligned apertures form respective slots (52) of a desired configuration in the core (50).Type: GrantFiled: December 16, 2009Date of Patent: November 22, 2011Assignee: In Motion TechnologiesInventors: Dean James Patterson, Steven Peter Camilleri, Lyell Douglas Embery

Publication number: 20110221297Abstract: A stator 20 for an axial flux machine such as a motor or generator. The stator includes a stator core 32 having a back plane 24 which in use is disposed perpendicularly about a rotational axis of the machine. A plurality of teeth 26 extend axially from the back plane so as to form winding receiving slots 28 between adjacent teeth. The stator also includes an electrical winding 30 including a plurality of coils 32, each coil being located about a tooth of the stator core and being electrically isolated from the stator tooth by means of an insulating former 34 having a shape which closely conforms to the shape of the stator tooth. The coils 32 are interconnected to form the winding 30. A method of constructing a stator is also disclosed.Type: ApplicationFiled: September 29, 2009Publication date: September 15, 2011Inventors: Charles Richard Langford, Steven Peter Camilleri, Rafal Pawel Rohoza

Publication number: 20100164316Abstract: A device for positioning a planar array of magnets within a permanent magnet electrical machine of the type having a rotor and stator with an air gap there between. The device includes a body made of non-ferrous material and having a first side which is attachable to the rotor and a second side which, in an assembled machine, faces the air gap. The first side of the body has a plurality of recesses therein for receiving a corresponding plurality of magnets. The recesses are shaped and arranged to separate the magnets from each other and maintain a consistent spacing between them. When the device is attached to the rotor the magnets are held in a fixed position against the rotor. The electrical machine may be a motor or a generator.Type: ApplicationFiled: April 29, 2008Publication date: July 1, 2010Applicant: IN MOTION TECHNOLOGIES PTY LIMITEDInventors: Charles Richard Langford, Steven Peter Camilleri, Dean James Patterson

Publication number: 20100164313Abstract: An axial flux electrical machine including a housing, a stator located within the housing, a rotatable shaft carried by the housing by means of at least a main bearing, and a rotor fixed to the shaft within the housing. Magnetic attractive forces between the rotor and the stator produce an axial thrust on the main bearing and a biasing means (preferably in the form of a spring) is arranged to urge the shaft in a direction opposite to the axial thrust so as to reduce the net load on the main bearing. This reduction in net load on the main bearing increases bearing life and improves motor efficiency.Type: ApplicationFiled: April 29, 2008Publication date: July 1, 2010Applicant: IN MOTION TECHNOLOGIES PTY LIMITEDInventors: Charles Richard Langford, Steven Peter Camilleri

Patent number: 7708697Abstract: Airway monitoring apparatus 30 includes a driver 6 for applying sound in the audible frequency range to the airway of a subject and a detector 7 for monitoring the response of the airway, e.g. by detecting transmitted sound signal components and/or reflected sound signal components. Variations in the detected sound signal, e.g. energy, due to attenuation of the signal, give an indication of the state of the airway, e.g. airway patency, and can be used to monitor sleep-disordered breathing events, such as apnea and hypopnea, and to provide a breathing event index, e.g. AHI. The apparatus may provide servo-control for a respiratory assist device, such as a positive airway pressure device, so as to provide an appropriate pressure level setting. It may allow for home use of such devices and for home titration. It may also assist in discriminating central and obstructive breathing events, and in providing a measure of airway resistance.Type: GrantFiled: April 15, 2005Date of Patent: May 4, 2010Assignee: Pulmosonix Pty LtdInventors: Malcolm Howard Wilkinson, Clive Andrew Ramsden, Philip John Berger, Peter Camilleri, Jacqueline Anne Wilson, Frank Samuhel

Patent number: 7521834Abstract: A poly-phase electromagnetic device having n winding phases (n>2) wherein each phase is made from a single conductor strand wound in a lap form configuration. The windings are configured such that on assembly to a slotted magnetically conducive base a maximum of n?1 end turns overlapping is achieved so that the slot packing density can be optimized. The preferred configurations also enable neat and compact terminations which facilitates efficient packaging of the completed device. The windings are made either from discrete bobbins which are electrically interconnected upon assembly to the base, or alternatively from strings of continuously formed sub-windings. The latter process in particular enables full or partial automation of the winding and/or assembly process.Type: GrantFiled: November 13, 2003Date of Patent: April 21, 2009Inventors: Dean James Patterson, Byron John Kennedy, Steven Peter Camilleri, Benjamin David Guymer, Matthew Campbell Greaves
