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...

Embodiment Construction

[0022] The present invention can be embodied in many different forms. While the drawings illustrate and the specification describes certain preferred embodiments of the invention, it is to be understood that this disclosure is by way of example only. There is no intention to limit the principles of the invention to the particular embodiments disclosed.

[0023] first reference Figure 1-2 , a digital compressor assembly 20 constructed in accordance with the principles of one embodiment of the present invention is described for various purposes. The digital compressor assembly 20 is configured to provide variable capacity regulation. While the digital compressor assembly 20 may be used in a variety of applications, the illustrated embodiment has particular utility when the digital compressor assembly 20 is configured for use as part of an air conditioning system.

[0024] In a way like regular, specific quick references figure 2 , the digital compressor assembly 20 general...
