AI Technical Summary

Problems solved by technology

For example, the two-speed motor is very complex to manufacture and often produces only satisfactory performance results
The fully variable speed motors tend to achieve increased system performance over two speed motors, but require complex and expensive drives to continuously vary the motor speed
The complexity of these existing systems to vary the speed of the motor for the compressor not only entails additional manufacturing costs, but can also cause maintenance and / or reliability issues

Abstract

A digital compressor with a direct-start brushless permanent magnet motor includes a housing, a compression mechanism and a drive structure disposed within the housing. The compression mechanism includes first and second scroll members movable relative to each other between loaded and unloaded conditions. The drive mechanism is in driving engagement with at least one scroll member for orbiting one scroll member relative to the other scroll member in a generally annular path without rotation and includes a direct actuated brushless permanent magnetic motor. The direct start thirty permanent magnet motor includes a plurality of permanent magnets mounted on and generally extending axially along the rotor core body of the motor. The digital compressor package provides improved overall system performance to meet efficiency standards.

Description

technical field [0001] The present invention generally relates to a digital compressor assembly configured to provide variable capacity regulation. More specifically, the present invention relates to a digital compressor comprising a compression mechanism having a mechanical element movable between a loaded state and an unloaded state, wherein the compression mechanism is powered by a direct start brushless permanent magnet motor Driven by the drive mechanism. Background technique [0002] Those of ordinary skill in the art will know that compressors are commonly used in various industrial applications. For example, some conventional air conditioning systems often use compressors that are either operating at maximum capacity or turned off in order to regulate the temperature of a room. A thermostat can be used to measure the temperature of the surrounding atmosphere and start the compressor if the temperature of the surrounding atmosphere deviates far from the desired temp...
