    Abstract: A system and method are provided for a variable speed compressor with a control module that controls an operating frequency of the variable speed compressor. The control module stores a prohibited frequency range that includes a resonant frequency of the variable speed compressor and an allowed upper frequency above the prohibited frequency range and an allowed lower frequency below the prohibited frequency range. The control module determines a requested frequency and operates the variable speed compressor at the allowed upper frequency for an upper frequency operating time and at the allowed lower frequency for a lower frequency operating time when the requested frequency is within the prohibited frequency range. The control module determines the upper frequency operating time and the lower frequency operating time such that a time-averaged frequency output over the upper frequency operating time and the lower frequency operating time corresponds to the requested frequency.

    Abstract: Scroll members for scroll compressors made from one or more near-net shaped powder metal processes, either wholly or partially fabricated together from sections. In certain variations, the involute scroll portion of the scroll member has a modified terminal end region. The terminal end region may include an as-sintered coupling feature comprising a tip component that forms a contact surface for contacting an opposing scroll member during compressor operation. The tip component can be a tip seal or a tip cap received by the as-sintered coupling feature. The tip cap may be sinter-bonded or otherwise coupled to the terminal end region. In other variations, a terminal end region may comprise a second material including a tribological material that forms a contact surface. Methods of making such scroll members for scroll compressors are also provided.

    Abstract: Anti-wear surface coatings and methods for making them are provided. Such anti-wear surface coatings are particularly suitable for use in a compressor, such as a scroll or rotary compressor. A precursor powder material can be applied via spraying to a wear surface of a metal component of the scroll or rotary compressor. The precursor powder material comprises a powderized thermoplastic polymer (e.g., PEEK), a first lubricant particle (e.g., molybdenum disulfide (MoS2)) and a second lubricant particle (e.g., polytetrafluoroethylene (PTFE)), which is heated to form a substantially uniform coating covering the underlying metal component having a thickness of less than or equal to about 0.006 inches (about 152 μm). The anti-wear surface coating can be used on a face seal for a bellows-type shaft seal for compressors.
