Publication number: 20080179981Abstract: A high phase order induction machine wound and permitted by coil symmetry to operate at fewer than the magnetically optimal number of poles is constrained by symmetry to be a two pole machine and be capable of operating on odd harmonics only, but with back-iron, end rings, and rotor core optimized for 10 pole operation, might be used normally in ‘5th harmonic’ mode, with ‘7th harmonic’ utilized to engage the ‘mesh effect’. Such a machine thus appears to be operating in the ‘1.4 harmonic’. A high phase order induction machine driven by a second harmonic drive, in which a symmetry imposed by full span windings is broken. This may be most simply accomplished through the use of short pitch windings. Other possible approaches include using non-wound slot drive, and using toroidal windings which localize coils to individual slots.Type: ApplicationFiled: January 9, 2008Publication date: July 31, 2008Inventor: Jonathan Sidney Edelson

Patent number: 7375483Abstract: In the present invention, several polyphase devices are connected together: an inverter, and electrical rotating machine, and a resistive load or braking resistor. The purpose of the resistive load is to dissipate excess electrical power which may be produced when the inverter acts to slow down the rotating machine, causing the rotating machine to act as a generator. In common art, this resistive load is a single DC resistor coupled to the DC link of the inverter via a separate resistor control transistor. In the present invention, the resistive load is a mesh connected array of resistors, and is electrically connected to the same inverter output terminals that the rotating machine is connected to. When it is desired that the resistors absorb energy, for example from a braking operation, then the harmonic content of the inverter output is adjusted, thus placing voltage differences across the resistor array and causing current to flow in the resistors.Type: GrantFiled: October 23, 2006Date of Patent: May 20, 2008Assignee: Borealis Technical LimitedInventor: Jonathan Sidney Edelson

Patent number: 7327105Abstract: An electrical rotating apparatus is provided that has variable impedance. This is achieved by connecting one of the polyphase components of the apparatus in a mesh connection. The spanning value, L, of such a mesh connection may be varied by changing the harmonic content supplied by an inverter component. Also provided is a method for connecting an inverter to a motor, wherein a switching arrangement permits the simple alteration between various mesh connections of different span value, changing thereby the Volts/Hertz ratio of the motor.Type: GrantFiled: September 21, 2006Date of Patent: February 5, 2008Assignee: Borealis Technical LimitedInventor: Jonathan Sidney Edelson
