20100182038Setup and method for testing a permanent magnet motor - A test setup for a permanent magnet motor provides a method for identifying symmetry or asymmetry in the magnetic fields of the motor's permanent magnets. The setup comprises a test circuit that includes a fixed reference node that provides a stable reference to which the motor's common node can be compared. Observing the waveform of the voltage between the two nodes while the motor is running helps identify an imbalance in the magnetic fields of the motor's permanent magnets.07-22-2010
20110041533SCREW COMPRESSOR DRIVE CONTROL - An embodiment of method used to control operation of a screw compressor of a refrigeration system may include receiving status signals regarding operation of the screw compressor of the refrigeration system. The method may further include determining an operating point of the screw compressor based upon the received status signals, and selecting a torque profile for the screw compressor based upon the operating point. The method may also include driving the screw compressor per the selected torque profile. Refrigeration systems and compressor systems suitable for implementing the method are also presented.02-24-2011
20110179644System for protecting bearings and seals of refrigerant compressor - To protect the bearings, lubricant and seals of a refrigerant compressor, the compressor includes one or more inductors for mitigating a high frequency common mode current that produces a high frequency shaft voltage. Each inductor is a ring of magnetic material encircling three insulated cables that convey three-phase power from an adjustable frequency drive to the compressor's motor. Without the inductors, the high frequency shaft voltage can become damagingly high due to the length of a cast iron housing that can be particularly long if the housing contains both a motor and several centrifugal impellers. The high frequency shaft voltage is just one component of a composite adverse shaft voltage. Another component, known as an operationally induced shaft voltage, can be reduced by a grounding contact, so instead of using just an inductor or just a contact, both can be used to provide a total solution to the problem.07-28-2011
20120087815CENTRIFUGAL COMPRESSOR ASSEMBLY AND METHOD - A centrifugal compressor assembly for compressing refrigerant in a 250-ton capacity or larger chiller system comprising a motor, preferably a compact, high energy density motor or permanent magnet motor, for driving a shaft at a range of sustained operating speeds under the control of a variable speed drive. Another embodiment of the centrifugal compressor assembly comprises a mixed flow impeller and a vaneless diffuser sized such that a final stage compressor operates with an optimal specific speed range for targeted combinations of head and capacity, while a non-final stage compressor operates above the optimum specific speed of the final stage compressor. Another embodiment of the centrifugal compressor assembly comprises an integrated inlet flow conditioning assembly to condition flow of refrigerant into an impeller to achieve a target approximately constant angle swirl distribution with minimal guide vane turning.04-12-2012

20120125797ORGANIZING STRAP SET - An organizing device is designed to be arranged to surround sides or edges of one or more items to securely hold the items together. The organizing device includes a first strap and a second strap. The first and second straps are held together at an attachment area in the mid-section of each strap. The organizing device also includes connection means located at each end area of the first and second straps. The connection means allow the areas of the first strap and end areas of the second strap to connect together and form an engaged closure around a group of items. The organizing strap device also features a method of identifying the group of items contained within the straps, such as a pre-printed label, a small pocket configured to hold an insert or an area on which may be written the contents of the organizing device.05-24-2012
