| Systems and methods are provided for cooling bearings or other objects. Such cooling may be accomplished by expanding a compressed gas in a cooling channel surrounding a bearing and allowing the expanded air to come into direct contact with the bearing. Expanding a compressed gas in local proximity of the bearing takes advantage of the Joule-Thompson expansion of gas, resulting in a substantial drop in gas temperature, thereby maximizing the cooling potential of the gas being directly applied to the bearing. Cooling bearings in this manner extends their operational life and enables them to operate at the desired speeds. A housing may be provided for receiving a compressed gas, expanding the compressed gas to a predetermined pressure, enabling the expanded gas to directly contact the bearing, and exhausting the expanded gas. | ||||||

| In an electric vehicle, the traction motor is driven from a battery by way of a controllable electric power switcher. In operation of the switcher, the power losses of the switches depends upon the power being handled; during acceleration the power is high, and at constant speed on level ground the power is small. Thus, the power nulldissipatednull by the switches varies with time. A cooler transfers heat from the switcher. During acceleration, the cooler may not be sufficient to limit the instantaneous switch temperature. A phase-change heat nullsinknull coupled to the switches absorbs heat from the switches during hard acceleration, and returns the heat to the cooler under more constant-speed conditions. | ||||||

Radial slots between the ducts and an air gap between the laminated stator core and a rotor are spaced from one another at an axial distance which decreases toward a turbomachine-distal side of the laminated stator core so as to compensate a temperature gradient caused by the one-sided cooling. | ||||||

| 80 | Electric motor with rotor being a drive wheel | US09212127 | 1998-12-15 | US06703742B1 | 2004-03-09 | Adam K. Brandley; John R. Irwin |
| An electric motor with rotor being a drive wheel. The drive wheel has one or more permanent magnets attached to said drive wheel with opposite magnetic poles adjacent to one another. One or more electromagnets are attached to the structure to which the drive wheel is rotatably connected. A sensor determines the location of the permanent magnets. This information is utilized to assure that the electromagnets are energized only when the resultant magnetic fields will interact with the magnetic fields of the permanent magnet to produce a force on the drive wheel that will cause rotation in the desired direction. Three principal embodiments are employed. In a first embodiment, a computer periodically activates a switch to send pulsed voltage to the electromagnets; the percentage of the period of each pulse during which the voltage is non-zero determines the speed of the drive wheel. In a second embodiment, the computer is replaced with a timing circuit that controls the switch. And in a third embodiment, the output from the sensor directly controls the switch. | ||||||
