Disclosed are a motor for a compressor and a hermetic compressor having the same. An aluminum coil cheaper than a copper coil is used in the motor for the compressor, a ratio between the aluminum coil and a stator core is set, and sectional areas of main and sub slot portions of the stator core and the numbers thereof are adjusted to be suitable for usage conditions, whereby fabricating costs of the motor for the compressor and the hermetic compressor can drastically be reduced and efficiencies thereof can be improved.

Motor for compressor and hermetic compressor having the same

Disclosed are a motor for a compressor and a hermetic compressor having the same. An aluminum coil cheaper than a copper coil is used in the motor for the compressor, to thusly reduce a fabricating cost. Also, a ratio of a height of end coil of a coil to an inner diameter of a stator is appropriately designed or a ratio of an entire area of slot portions to the inner diameter of the stator is appropriately designed, and simultaneously a ratio of the inner diameter of the stator to a width of the tooth portion is appropriately designed, so as to previously prevent a deterioration of damping effect, increase in noise, lowering of efficiency, reduction of driven torque, all caused due to the use of the aluminum coil.

The present invention relates to a discharging noise system of a hermetic compressor. The present invention includes a first discharging noise suppressor () provided at one side end of a cylinder blockto firstly reduce noise and pulsation of work fluid compressed in and discharged from a compressing chamber () formed to be bored through the cylinder block () in a fore and aft direction, a second discharging noise suppressor (') provided at the other side end of the cylinder block () and communicating with the first discharging noise suppressorto secondarily reduce noise and pulsation of the work fluid with noise and pulsation reduced by the first discharging noise suppressor (), a connection pipe () for allowing the first and second discharging noise suppressors () and (&#x2032;) to communicate with each other to form a channel for allowing the work fluid to move, the connection pipe () having a length longer than a shortest straight distance between the discharging noise suppressors (and&#x2032;), and a discharging pipe () provided at the second discharging noise suppressor (&#x2032;) to form a channel through which the work fluid is discharged to the outside. According to the present invention configured as above, the connection pipe is relatively long to reduce pulsation, thereby improving operating characteristics of the hermetic compressor, so that vibration generated by the pulsation is reduced to improve durability of the hermetic compressor.
