These motors are designed to have a high starting torque to overcome the high compressor load with a minimum energy input. The high-rel high-efficiency motor is designed to operate from 336 to 400hz at a constant 208 AC, 3 phase voltage. The motor develops 10.5 Hp at 6,900 rpm with a motor efficiency of 92% yet weighs less than 22 lbs. The very compact size of 5.2 inches in diameter by 7.9 inches long makes it desirable where space is at a premium. 28 volt DC inverter/converter driven models are available as well. The motor's rotor is dynamically balanced and incorporates sealed ball bearings providing for a long quiet life. Their construction, materials and finishes enable them to meet MIL-SPECS and operate in harsh environments. They are class "H" insulated allowing them to operate in high ambient temperatures over a long life. This motor performs a dual purpose in that it also drives the impeller which forces cooling air through the heat exchangers as well as its primary function of driving the compressor.
