PURPOSE:To reduce resilient vibration of rotary shaft to be produced under high speed by making a notch for containing the coil end of stator in main bearing for rotary shaft thereby lowering the rotor and stator thus shortening the rotary shaft. CONSTITUTION:An enclosed motor compressor is supported by a plurality of supporting springs 2 arranged with equi-interval at the lower section of case 1. The compressor section is comprised of a gas chamber having main bearing 3, a sub-bearing 4, a cylinder 5 and a roller 6 and an eccentric rotary shaft 7 where the rotation of the rotary shaft 7 will cause compression/expansion of gas in gas chamber to perform heat-exchange. Here, a notch for containing the coil end 12 of stator 11 is made in main bearing 3. When containing the coil end 12 in main bearing 3 through the notch, the rotor 8 and the stator 11 are lowered to shorten the rotary shaft 7. Consequently, resilient vibration of rotary shaft 7 to be produced under high speed can be reduced.
