摘要： A magnetic HVIL system for a drive in a transport application includes a Hall effect sensor within at least one housing of the drive that includes terminals and a removable cover. The removable cover includes a magnet having a magnetic field that is detectable by the Hall effect sensor when the removable cover is installed on the housing. The magnetic field of the magnet is not detectable by the Hall effect sensor when the removable cover is removed from the housing. The magnet HVIL system is configured to be operable to enable active operation of the drive when the Hall effect sensor detects the magnetic field of the magnet and is in a closed circuit condition and disable operation of the drive when the Hall effect sensor does not detect the magnetic field of the magnet and is in an open circuit condition.

摘要： A compressor may include a compressor shell, a motor, a compression mechanism, and an assembly that houses an electronic component. The electronic component may control operation of the compressor and/or diagnose compressor faults. The assembly may include a shell, an electronic component, a fan, and an airflow deflector. The shell member may define an enclosure having an internal cavity. The fan and the electronic component may be disposed within the internal cavity. The airflow deflector may include a base portion, a first leg, and a second leg. The first and second legs may be spaced apart from each other and extend from the base portion. The fan may force air against the base portion. A first portion of the air may flow from the base portion along the first leg. A second portion of the air may flow from the base portion along the second leg.

摘要： A compressor according to the principles of the present disclosure includes a shell, a compression mechanism, a driveshaft, a drive bearing cavity, and a drive bearing. The compression mechanism is disposed within the shell and includes an orbiting scroll member and a non-orbiting scroll member. The orbiting scroll member includes a baseplate and a tubular portion extending axially from the baseplate. The driveshaft is drivingly engaged with the orbiting scroll member. The drive bearing cavity is disposed between an outer radial surface of the driveshaft and an inner radial surface of the tubular portion of the orbiting scroll member. The baseplate of the orbiting scroll member defines a first discharge passage in fluid communication with the drive bearing cavity. The drive bearing is disposed in the drive bearing cavity and is disposed about the driveshaft adjacent to the first end of the driveshaft.

摘要： Scroll compressor designs are provided to minimize vibration, sound, and noise transmission. The scroll compressor has a bearing housing, and orbiting and non-orbiting scroll members. The non-orbiting scroll member has a radially extending flanged portion with at least one aperture substantially aligned with the axially extending bore. At least one fastener is disposed within the aperture and the bore. A sound isolation member contacts at least one of the non-orbiting scroll member, the fastener, or the bearing housing, to reduce or eliminate noise transmission. The sound isolation member may be formed of a polymeric composite having an acoustic impedance value greater than the surrounding materials. The sound isolation member may be an annular washer, an O-ring, or a biasing member, by way of non-limiting example. In other variations, fluid passages are provided within the fastener and/or bearing housing to facilitate entry of lubricant oil to further dampen sound and noise.
