Three new hermetic motors for use in scroll and screw compressors have been introduced. Two motor designs are specifically for use in scroll compressors for residential and light commercial air conditioning. The motors are for 7.5- to 15-ton compressors. A new 108-frame motor is for use in screw compressors in commercial air conditioning and industrial chiller applications. The unit combines two existing motor sizes, offering the efficiency of the smaller unit with the increased performance of the larger one, says the company. The motor is three phase, operating at 3,600 rpm, with an output range of 50 to 150 hp.
