Appl. No.:

11/655421

Inventors:

Donald Steele - Cohasset MA, US
Edward Lovelace - Arlington MA, US
Roger Dickinson - Torrington CT, US

International Classification:

H02K 1/12

US Classification:

310258000, 310152000, 31004000R

Abstract:

A system for and method of rotating a transfer wheel providing heat and/or moisture exchange between two counter-flowing air streams. The system comprises: a frame; a transfer wheel including a transfer matrix mounted and rotationally secured relative to the frame so that the wheel can rotate through the two counter-flowing air streams and heat and/or moisture can be transferred between the two counter-flowing air streams; and a first plurality of motor components fixedly mounted relative to the wheel so that components of the first plurality function as a rotor of a motor, and a second plurality of motor components fixedly mounted relative to the frame so that components of the second plurality function as a stator of a motor; wherein power supplied to motor components of the second plurality causes the transfer wheel to rotate through the two counter-flowing air streams.

US Classification:

165 9, 310 67 R

Abstract:

The disclosed system provides heat and/or moisture transfer between two counter-flowing air streams. The system comprises: a frame; a transfer wheel having a periphery spaced from the frame so as to form a gap therebetween, and including a transfer matrix mounted and rotationally secured relative to the frame so that the wheel can simultaneously rotate through the two separate, counter-flowing air streams; a sealing arrangement configured so as to seal the transfer wheel to the frame so that as the wheel rotates through the two separate counter-flowing air streams, the two air streams flow through the transfer matrix while remaining sealed from one another; and an electromagnetic actuator including rotational components secured relative to the wheel configured to generate flux across the gap and stationary components secured relative to the frame configured to impart a tractive force to the rotational components in response to polyphase power supplied to the stationary components.

International Classification:

H02K 5/16
H02K 7/08

US Classification:

310090000

Abstract:

An integrated bearing system () for supporting a rotatable shaft journal (). The system () comprises a foil bearing () in combination with a magnetic field generating device () that produces a magnetic bearing capability to the rotatable shaft journal (). The foil bearing () is integrated into the magnetic field generating device (), leaving an air gap between the shaft journal () and the foil bearing (). Under normal operating conditions, the magnetic field generating device () and the foil bearing () each provide a portion of the support to the shaft journal ().

International Classification:

H02K 1/27
H02K 9/06
B64C 11/02

Abstract:

In an example, a rotor for an electric motor includes an inner hub, an outer rim, and a plurality of slats. Each slat of the plurality of slats has a first end at the inner hub and a second end at the outer rim. The rotor is configured to drive a plurality of propeller blades that provide force for an aerial vehicle. Additionally or alternatively, a rotor for an electric motor includes a housing that includes a first retaining structure and a second retaining structure that are configured to apply a force that is directed radially outward against a magnet to hold the magnet against the housing. The rotor is configured to drive a plurality of propeller blades that provide force for an aerial vehicle.

International Classification:

B60W 20/13
H02P 6/182
B60L 15/20

Abstract:

A system includes a computing device with memory configured to store instructions and a processor to execute the instructions for operations that include receiving information that represents when a voltage of an energy storage system of a hybrid vehicle decreases to a pre-determined voltage value, determining a value of a back electromagnetic field (EMF) generated by an electric motor powered by the energy storage system when a commanded torque of the electric motor is zero, and causing a regenerative current to be provided to the energy storage system. The regenerative current provided is configured to maintain the voltage of the energy storage system at or above the pre-determined voltage value responsive to the commanded torque of the electric motor being zero and the voltage of the energy storage system being reduced to the pre-determined voltage value.

Abstract:

A battery cooling system is described, including a thermally conductive cooling plate having a first surface and a second surface opposite the first surface. A first group of battery cells may be disposed on the first surface of the cooling plate, a second group of battery cells may be disposed on the second surface of the cooling plate, and a thermally conductive interstitial layer may be coupled between the cooling plate and the first group of battery cells, and between the cooling plate and the second group of battery cells. The cooling plate is configured to draw heat from the first group and the second group of the battery cells.

Abstract:

A computing device-implemented method includes receiving data representative of one or more operational parameters for a vehicle, calculating the fuel rate required for an internal combustion engine of the vehicle to respond to the operational parameters, determining if the required fuel rate exceeds a threshold which would cause a state change in the performance of the internal combustion engine, if the required fuel rate exceeds the threshold, calculating an amount of assistance required for an electric hybrid traction motor to provide to a drivetrain of the vehicle to implement the received operational parameters of the vehicle, and providing the amount of assistance to the drivetrain of the vehicle, thereby preventing the state change in the performance of the internal combustion engine.
